 | GLAZES FROM ... WELL, ALL OVER THE PLACE
best to test test test . This page will act as a store-house of glazes for those interested. It is also a place that I can place all the glazes that I find, so I don't lose those little pieces of paper. I will post here an ongoing collection of glazes that I have found from books, internet sources, workshops etc. etc. etc. These glazes have not nescessarily been tested by me, so if you have found your way to this page, remember to test test test. from http://finemessblog.blogspot.com/search/label/Glazes%20and%20Glazing

Nicecolonial (bluish slate) over white slip Well I finally got around totyping this thing up...^9-10 Blues Thank you one and all for all thedonated recipes. I only tested 31 out of almost 100 I received. I'llcontinue testing and reporting as the winter DRAGS on. All the glazeswere tested on #900 Miller clay which is a toasty ^10 stoneware. Oneside of the test tile was brushed with a thick coating of CynthiaBringle's wet/dry white slip. Each glaze was dipped in threethicknesses on a heavily textured tile. All tiles were fired to a(hard)^9 (10 tipping)reduction firing. 1 hr. Body reduction at ^08and 1 hr. glaze reduction at ^9 then a quick reox. before shutdown.Any time potash or Custer spar is called for, I used G-200. All ballclay is OM-4 . Many glazes I substituted 75% of the amount of Bariumwith Strontium. All kaolin is EPK. Remember... glazes don't travelwell. Your results will probably be TOTALLY different. Please testbefore use.

Itis best applied by spraying but can be dipped, poured, etc. You haveto work with the thickness to got the desired result. A lightapplication will orange peel like a salt glaze while heavierapplications will run. Too much thickness and you will getblistering. This glaze works well with most oxides. It also worksbest on porcelain or with white slips but don't be afraid to tryanything...you never know. You can get this glaze to work at cone 8and 9 by substituting Ball Clay for Kaolin.

Because it's used by electric kiln potters the light greencolour is given by copper carbonate.

Kevin O'Hara asked about a reliable base formula foran ash glaze. We have been using the glaze base provided by HaroldMcWhinnie in his November 1986 'Ceramics Monthly' article (AMultipurpose Glaze, p. 75). We repeat it below. If you have anyquestions about this glaze, we believe that Harold is now monitoringthe Clayart list regularly. We have experimented with various typesof wood ash. We now use pecan hull ash. Fortunately, we have manypecan trees in the area along with cracking plants that kindly supplyus with the hulls. There is a lot of oil in pecan hulls (includingmany nuts) so they burn hot with very little but fine ash. We do notwash this ash; however, we have found that we must wash other woodash. We experimented with Victoria's Secret ash (burned their ceaselycatalogs) but found it full of trash and required cleaning.

Alittle more inFiring: Some salting is involved in all of the woodfirings I have used this slip in- generally about 1 1/2 - 3 poundsper chamber. These are not super long firings -in the 14-18 hourrange, so a lot of the surface effect comes from the salt rather thanfrom a lot of ash. I have also used it in salt/soda and it lookedgreat-more orange than brown. I haven't used it with a real heavyload of salt but if you try it I'd like yo know how it looks. Mixjust a little on the thin side and its works on bisque just as wellas on geenware I've been working up some variations using Helmerkaolin, but haven't hit one I like yet.

They were fired to cone 10 Ox. buy my wife, LindaOwen, in her trusty Skutt Kiln. Thanx Linda! The two glazes arenearly identical. I didn't expect that, but ya never know. Theoriginal formula with gerstley borate has more calcium-borate-ironcrystals floating in the matrix but you really can't see this withouta hand lens. A customer who has purchased pots with the originalformula would be hard pressed to tell the difference. I feel likeI've just taken the Pepsi Challenge!! The tests were fired onporcelain. Four tiles were made of each glaze, eight in all and theseparate formulas were fired side by side in the top, middle, andbottom of the kiln. No significant differences were seen. I mightalso mention that I used English Bone Ash, and not Tri-Calcium Phos.All the tiles were inspected with a hand lens and no crazing wasevident in either formula. A separate set has been fired to cone 10 Rbut won't be available until tomorrow. That's about it for now,e-mail me or post to clayart if I've forgotten to mention anythin,and I probably have...it's my hobby! The formulas and receipes areposted below.

I think I'd rather have more RIO thanCobalt, due to cost, but it's hard to knock success, and it breaks toa nice blue when white is over it. -- Also, it wouldn't surprise me abit if the bone ash is superfluous The recent posts on foodsafe blackhave prompted me to state my own opinion on black glazes. I thinkblack glazes need not be avoided totally for foodware, but commonsense argues that some blacks are better than others. If the baseglaze doesn't leach harmful chemicals, then one must concentrate oncombinations of oxides to produce the color with the least toxicity.Though I've never seen an authoritative ordered list of nastychemicals, Red Iron Oxide, Cobalt Carb, and Copper Carb seem safer tome than Manganese Dioxide, Nickel, Cadmium, and Chrome. From an oldLaurel's Kitchen cookbook, I read that Iron, Copper, Zinc, Manganese,Cobalt, Chromium, Nickel, Tin, and even Vanadium are all traceminerals essential for animals. I assert that most glazes releasetraces at best of these minerals. However, we are caught in a worldwhich can measure in Parts per Billion, and all kinds of things looksignificant at that level. I sometimes wonder how long the ozoneholes at the poles existed before we had the means to ascertain theirexistence.

Ihave used this glaze for years now with good success but it requirescone 10 flat and 11 tipping to mature. I would like to lower thetemp. to a 9 flat and cone 10 tipping but don't really know where tobegin. I fire a 35 cubic ft. Minnesota Flat Top with natural gas. Ifanyone can get me started, I would be grateful. Also, I have beentrying to paint with stains over this glaze. I use them mixed withwater and gerstly borate but can't get a smooth flow going. I waswondering how mixing the stains right in with some of the Buttermilkwould work. Does anyone have suggestions??? Many thanks for yourtime.

I may havelowered the temperature too much - so - mix this one (500 grams) andtest it in a cool part of your kiln (with large cones beside it. Thenmix equal parts (by volume) with your original. This will give youthe recipe between the two. If it is better than either the new one Iam sending add each ingrediant together (fome my new one and your oldone) to get the recipe for the middle one. Gerstley borate 10.5 +13.0 = 23.5 divided by 2 =11.75 for instance. By the way both glazesare seriously short of Alumina and Silica and oversupplied withMagnesium so don't consider this a durable glaze. There is not atoxicity problem because there are no problematic oxides in the glaze- just be careful what you mix with and put under or over this glazein areas that will come in contact with food.

I have found that my blue celadonglaze, which is very similar to others given to you, likes all thereduction I can give it. I fire blue celadon pieces in the samefirings I go for carbon trapping with my shinos. The extra reductionalong with a good thick application of the blue celadon glaze, Ithink, encourages the bubbles trapped in the glaze which gives it anice softness to the glossy glaze. I introduce a heavy reduction atcone 010 through to cone 06 then lighten up a bit for the rest of thefiring. Also, drips melt out and do not show. Despite the onlyaverage amount of clay in the glaze, but high amount of feldspar andflint, the glaze does not run at all at cone 10 EPK helps and useSpanish Red Iron oxide and do not get any speckling. I feel the blueceladon glaze is much nicer on porcelain. You may need to add asuspender, I don't though. I have substituted Strontium Carbonate forhalf of the Barium and all of the Barium at 1 part Barium to 3/4parts Strontium and received just as nice results. I have theunderstanding from talking with other colleagues that the glazeshould be safe from Barium poisoning because it is a glossy glazewhere enough silica molecules have combined with the Barium moleculesto make it stable. But, I have never had it tested. Does anyone knowif this is true or not? Please reply.

Ionly tested 31 out of almost 100 I received. I'll continue testingand reporting as the winter DRAGS on. All the glazes were tested on#900 Miller clay which is a toasty ^10 stoneware. One side of thetest tile was brushed with a thick coating of Cynthia Bringle'swet/dry white slip. Each glaze was dipped in three thicknesses on aheavily textured tile. All tiles were fired to a (hard)^9 (10tipping)reduction firing. 1 hr. Body reduction at ^08 and 1 hr. glazereduction at ^9 then a quick reox. before shutdown. Any time potashor Custer spar is called for, I used G-200. All ball clay is OM-4 .Many glazes I substituted 75% of the amount of Barium with Strontium.All kaolin is EPK.

So, TC's RCP comesout like this: Firstly, as noted we'd use a different feldspar (stilla K one tho') and we switch from barium carbonate to strontiumcarbonate since Fusion (Ontario Potters Assn) has a campaign going(launched by Ron Roy) to avoid the use of barium over 5% content inthe glaze mix. I fully expect this version to perform like theoriginal. Both might crackle on a tight porcelain. Should be funtrying the three.

It is often said that black iron oxide gives bluerceledons, so you might want to try that. It is important to keep aglaze's content of titanium at a near zero level to develop blueceledons as well. Titanium will encourage green. I ran your Neph Syceledon through Insight and you could reduce the crazing and maybeeliminate it by the direct substitution of potash feldspar for theNeph Sy. You might want to try both Custer and G-200. Custer ishigher in silica and would be the most effective one to lower theglazes expansion. G-200 will give a bit better melt Ithink..........Craig craig martell <ashglaze@teleport.com>Glaze name: Charlie D ManganeseCone: 10Color: blackTesting: UntestedSurface: satinFiring: reductionRecipe:Custer spar 20.00Kona F-4 feldspar 20.00Whiting 2.00Dolomite 15.00Talc 13.00Ball clay 10.00Flint 20.00Bentonite 2.00Manganese dioxide 4.00Comments:then add 2% Bentonite and 4% Manganese (In particular, lately I'vewanted to use a reliable cone 10 black satin/waxy glaze, in case youknow of one.)

It is smooth to the touch, pleasing to feel. Very tolerant andforgiving. It is somewhat uninteresting by itself although it is as stable asyou can imagine. Add colorants for the real action!*How long have you been using this glaze? 8-10 years*Where is it used? Bob Kavanagh's studio.*Where did this recipe come from? I developed it over a few years.*What do you like most about this glaze? It is stable, adaptable, accepts diversecolors well, applies easily, is virtually fault free - a good friend.*Does this glaze tend to craze/crawl/pinhole/etc.? With the majolica, it may crawl if the glaze is applied VERY thickly.*How do different firing temperatures/atmospheres affect the glaze? It may be used in reduction as well as in oxidation, although I nowuse it only in oxidation. I developed it while I was working in areducing atmosphere. The differences between oxidation and reductionlie in the clarity of the glaze (much clearer in oxidation) and ofcourse the impact of reduction on iron bearing oxides.*How does the glaze behave on different clay bodies? Very adaptable to stoneware, porcelain, rough, smooth, etc.*What consistency should the glaze be for pouring/dipping? Dip hand into bucket; can hardly see skin under glaze on hand: thickcream.*How thickly should the glaze be applied to the pot? Varies with oxide addition. Likes to be moderately thick forrichest results.*How does this glaze interact with other glazes? I had not been happy with combining it with others, so I stopped. Itcan be layered with itself with different colorants in each layer.*What is your kiln type and size? 10 cubic foot, Tucker's Cone Art, electric*How do you typically fire? 0 to 212 in two hours: hold 10 minutes. 212 to 1040 at about 300 degrees an hour. very slowly from 1040 to 1070. as quickly as possible from 1070 to 2100. about 150 degrees an hour until cone 7-8.*Do you experience problems with the raw glaze? no problems*GlazeBase recipe* Submitted by: bob kavanagh (bkav@vax2.concordia.ca) ------------------------------------------------------------------------Variations --*Variations: berry rust: 10% red iron oxide deep river red: 20% RIO midnight blue: 5% cobalt carb., 2% RIO, 1% copper carb. silver yellow: 6% vanadium oxide, touch of rutile majolica: 7% tin oxideGlaze name: Clear Buttery Matt #415Cone: 10Color: translucent clearTesting: UntestedSurface: semi matteFiring: Ox. or Red.Recipe:Cornwall Stone 85.00Whiting 10.00Magnesium carbonate 5.00Comments:cone 10 clear matt.

On all our cone 10+firings, in ox or red., we have a great clear. In salt fire, however,if the vapor hits the inside of, say a bowl, or if the clear is onthe outside of the pot, then it crazes horribly. If we prevent thevapor from hitting the surface of the clear, it does well. (or if itis very thin on the outside of the pot). This glaze does very well inour wood fire kiln-no crazing at all. It will be matt if it doesn'tget a good cone 10 if that helps any.

Likes a fast cooling to developthat electric blue. One dip gives you brown, two dips a deep blue.Tends to break on ridges. Where real heavy you get white. Flows quitea bit, especially combined with other glazes. Watch your bottomfeet,try to give it a good foot or a strong ridge to stop flow.Tapering the bottom edge with a straight edge helps too. Otherwiseyour shelf will be a beautiful shade of blue. If thick, tends topinhole, likes to dry and be rubbed out before firing. Tempermentalglaze---can crawl just enough to make you crazy generally under rimsand on the inside of rims....probably is thicker there and shrinkswhen drying. To Mix, we've found it best to dissolve the Cornwallfirst and let set a bit, then add everything else. Screen through a40 once and an 80mesh twice for finest crystalization. This is acompilation of several background messages re: the Conrad Moonlight.We use Conrads Moonlight (which was discussed about 6 months agohere) with about 1/2%cobalt Carb. added. It's a cone 10 glaze. Ifirst started using it in electric firing, and a year ago switched togas. At first in the gas, it was muddier and tended toward rutileblue-green. Then, experimenting, we cooled the kiln faster to matchthe curve of the electrics. Voila, nice sharp crystals and blue. Italso seems to be quite sensitive to temperature, over fire it and itgrabs iron from anywhere and goes blue green or brownish. I alsomight note that it is quite sensitive to application. It must go onthick to develop a good blue. (even sometimes giving almost purple).Thick in the bucket, double dip as soon as the sheen leaves, drycompletely, then rub lightly everywhere and especially on compundcurves. This is a Cornwall recipe and tends to crawl if not thorughlybonded to the clay surface. The thickness required doesn't help.Don't know what it might do at c6 but if you can get it there, theabove notes might help. One note, I mentioned that it's sensitive totemp. It's happiest between 9-1/2 and 10-1/2. Also we use it on awhite stoneware. On iron body clays, it tends toward blue green orbrown-green...not too pretty. Joyce brought up a good pointThe rutileblue Moonlight from Conrad (G375) is r understand, most rutile bluesare. The way we work around this is to provide a ridge at the footand, when Betsy applies the glaze, she takes a stainless rib andcarves a taper into the ridge. Sounds time consuming, and is, but itgoes pretty fast after you've done (not had) a few. The main time welose pieces from running now is where there's an overlap with anotherglaze, especially Temmoku. But by keeping it high on the pot, it canbe controlled. Good Luck. It can be a fantastic rutile blue, bestI've seen. I'll be off the list for a week, at Rosen, but will pulldigests during the week.

A heavy reduction at the end is recommended. Firingtime should be between 12 and 20 hours. Not enough reduction duringthe firing will cause the glaze to be clear.*How long have you been using this glaze? I've used this glaze off and on for 2 years.*Where is it used? University of Houston*Where did this recipe come from? This could be a Carlton Ball glaze, but I'm not sure.*Is this glaze reliable? The firing process is what's difficult about this glaze. You shouldstart reducing around cone 5 and do a heavy reduction at the end.*Does this glaze tend to craze/crawl/pinhole/etc.? You should make sure the surface of the pot is clean of dust.*How do different firing temperatures/atmospheres affect the glaze? Too muddy of a reduction will cause the copper to burn out. Toolittle will cause the glaze to run clear.*How does the glaze behave on different clay bodies? White or light bodies are best, but it does work on red clay bodies.*What consistency should the glaze be for pouring/dipping? Once you have mixed the glaze with water, you need to use it thatday. A thick application is best. Dipped if possible. Once mixed theelements settle out and will not work if remixed.*How thickly should the glaze be applied to the pot? The thicker the better, but the glaze will run.*How does this glaze interact with other glazes? It works great with rutile glazes.*What is your kiln type and size? I used an updraft reduction kiln about 9 cubic feet.*How do you typically fire? I build temperature up to a cone 6 then reduce there for an hour,then go the rest of the way up reducing all the way. With a heavyreduction at the end. Then let it cool completely with all holesplugged and dampers shut tight.*Do you experience problems with the raw glaze? Keep materials dry until you are ready to use. It will not staymixed and the chemicals alter if left wet for more than 48 hours.*GlazeBase recipe* Submitted by: Suzanne (SuzZim@swbell.com) ------------------------------------------------------------------------Glaze name: Copper Red (Walter Donald Kring)Cone: 9 - 10 - 11Color: copper redTesting: UntestedSurface: glossy, shinyFiring: reductionRecipe:Gerstley borate 9.10Whiting 14.30Nepheline syenite 44.30Potash feldspar 6.20Kaolin 2.60Flint 23.60Copper carbonate 0.40Tin oxide 1.00Comments:The following two glazes are the copper red recipe's I've had themost success with from rafael molina-rodriguez (rafaelmolina-rodriguez)Glaze name: Copper Red 2Cone: 10Color: redTesting: UntestedSurface: Firing: reductionRecipe:Nepheline syenite 12.50Custer feldspar 22.40Silica 32.90Colemanite 15.80Zinc oxide 9.30Barium carbonate 7.00Copper carbonate 2.20Tin oxide 1.70Comments:submitted by: June M.

I fire this glaze to cone 10 just tipping.If over-fired the red starts to burn out. The glaze is a strong RED,which under heavy reduction and where it is thick tends toward an oilspot effect. Be careful with thick pplication at the bottom of thepiece, as there is a fine point at the end of the firing where theglaze tends to run. Presistance with this glaze is well worthwhile.submitted by: David Stuchbery. e-mail:stuchber@redgum.bendigo.latrobe.edu.auGlaze name: Copper Red COLEMAN'SCone: 10Color: RedTesting: Surface: shiny, glossyFiring: ReductionGlaze type: Copper redTransparency: Semi-opaqueRecipe:Silica 36.00Nepheline syenite 20.43Custer feldspar 15.57Whiting 15.73Colemanite 10.80EPK 1.48Tin oxide 1.72Copper carbonate 0.43Comments:from David Cuzick- (Silica -the finer the better to reduce crazing)note the very small percentage of copper carb. this glaze does not need toomuch reduction, it is a purple red.

I use it on porcelainmost of the time. Dear fellow potters, Here are two CONE 10 reductioncopper red glazes. I have used these glazes for years, they do work,but must be fired correctly to get the red. I will not go into thecorrect firing of copper reds because it depens so much on the kilnand burner set up you have. I have found that some kilns simply donot produce good copper reds by any method I was able to fire themwhile others produced reds easly. I fire in an Olsen 36 cu. ft. updraft soft brick kiln with only moderate reduction and get goodconsistant bright copper reds t hroughout the kiln. Good luck andgood potting.

But first letme tell you a bit about your current recipe. As you gave it, thisglaze is a high alkaline earth glaze, a bit low in alumina, butotherwise smack in the midfire range c4-c7. It's unusual in the factthat it has 5.2% Titanium oxide and this will cause problems,pinholing being one of them. The glaze is prone to pinholing becausethere's too much carbonate in the raw materials. The COE at 7.2 is abit high but it could well fit a stoneware of 6.+ COE. Ok. Here's thenew version. This version closely matches the Unity Formula of youroriginal. I have switched to Wollastonite and Talc to reduce thecarbonate level. You could also use copper oxide black 40 units, orcopper oxide red, 35 units and reduce the carbonate a bit more butthe copper oxides are very hard to disperse and you may get specklingif you do not thoroughly screen the mix. The gerstley borate ishigher than I'd wish but if I use Ferro frit 3134 (or 3195) in itsplace the alumina goes up almost 50% and the KNaO content goes uptoo, increasing the COE to 7.7 or higher; the glaze could crazemarkedly. The best course would be to try this mix first and see ifit gives you the blue-green you want without pinholes. If out-gassingis still a problem, then perhaps one could use half Gerstley B andhalf 3195. I suggest, if this sits ok with you, that you go thisroute and see what happens and only make a further revision ifneeded. Tom Buck <aa563@main.freenet.hamilton.on.ca> Sana's Green isactually a C10R recipe that I posted here a while back because I washaving pinhole problems with it.

I'll continue testing andreporting as the winter DRAGS on. All the glazes were tested on #900Miller clay which is a toasty ^10 stoneware. One side of the testtile was brushed with a thick coating of Cynthia Bringle's wet/drywhite slip. Each glaze was dipped in three thicknesses on a heavilytextured tile. All tiles were fired to a (hard)^9 (10tipping)reduction firing. 1 hr. Body reduction at ^08 and 1 hr. glazereduction at ^9 then a quick reox. before shutdown. Any time potashor Custer spar is called for, I used G-200. All ball clay is OM-4 .Many glazes I substituted 75% of the amount of Barium with Strontium.All kaolin is EPK.

As I previously mentioned, in OX put it overPORCELAIN SHINO & you get a funky rough surface in solid copper w/fine rusty flecks - this is thin. Thick edges are unattractive (?)white. If firing in REDTN, slow cool for max. orange. This is avariant of the famous Mamo glaze. If you want to try other colorants,drop out the tin (it's incl. to promote ornage) from the base as wellas dropping the RIO & bone ash. But BE CAREFUL - this glaze pullsapart if too thick in big fatal crawls. I abandoned it as a white forthis reason & I swear it once pulled so badly it broke (?) the pot itwas on.

Some firings are ok, thenwe'll have a terrible load even tho we fire the same schedule eachtime. We thot it might be the new water (it's softer, so we wonderedif it might have more sodium), but tried the 'old' water, got thesame blisters, altho not as bad (for a load or 2). We typically fire(propane) to ^10 tip touching, in about 11-12 hours) start reductionat ^012 at the coolest spot in the kiln. We take an hour from ^9 to^10, then usually leave the damper open for an hour to quick coolbefore we close it. We tried closing it immediately for a slow cool,hoping to smooth out the glaze, but still had blisters and had lostall our great blues. The temp is within 1/2 cone throughout the kiln,and reduction seems fairly even. The other thing is that it isn'tevery pot in that glaze. On one shelf, the pots on one side might beblistered and the other side fine, and one shelf up or down theopposite side is affected. It seems worse when the glaze is thin.Sometimes a re-fire helps smooth them out. Our 2 claybodies arePlainsman H443 (brown) and H551 (white). Could it be the clay? Wehave some blisters in other glazes too, altho not as bad. The onlycommon ingredient in custer spar. I hope I've given you enough infoto help me.

Continue moderate to lightreduction until cone 10 then a brief oxidation peroid of about 10minutes. If you over reduce it will be liver brown and under reducedwill be celadon. One solution to a problem (uneven, spotty reductionand under reduced)we had was to turn down the gas and air. To slow itdown and reduce at the above schedule. We were firing in an Alpineupdraft with blowers and just running the same schedule as the peoplewho fired before us. (It was a community center). They were firing at4 pounds pressure (natural gas) with the blowers at 70. Somethinglike that. But we reduced the gas and the air and the firing was 100%better. No more spotty reduction or unreduced pots.

It must be very thin on porcelain to turn orange,or try putting a wash of an iron rich glaze (I use temmoku) beforeapplying the shino.

One is probably wellknown, Shaner's shino, it is the one we use at Mohawk C's 'ceramicslab' stoney creek. As quoted this is a high alkali glaze (sodium andlithium) and unusually high alumina 1.6 moles (29.5% by weight). Thisglaze doesn't fit the pattern of C10R glazes but works if one appliesit carefully. (The iron comes from the raw materials and totals 0.01moles, 0.35%) A thin singlecoat yeilds variegated organge especiallyon a embossed surface. If a second coat is applied, one gets a greyedwhite, and if the glaze is even thicker it will crawl.

I've beenusing one for a few firings now that I like pretty well; it respondsin an interesting way to different atmospheres and clay bodies. Alittle more inFiring: Some salting is involved in all of the woodfirings I have used this slip in- generally about 1 1/2 - 3 poundsper chamber. These are not super long firings -in the 14-18 hourrange, so a lot of the surface effect comes from the salt rather thanfrom a lot of ash. I have also used it in salt/soda and it lookedgreat-more orange than brown. I haven't used it with a real heavyload of salt but if you try it I'd like yo know how it looks. Mixjust a little on the thin side and its works on bisque just as wellas on geenware I've been working up some variations using Helmerkaolin, but haven't hit one I like yet.

I put it on some test bowls madefrom Miller 510, which is a packaged cone 10 white stoneware, themakeup of which I don't know. The slip was a little thin when I mixedit , so I used a little epsom salts to thicken to what I am used towith an Avery slip going on leather hard. Fired to ^10, it flashedgorgeously, but also cracked and jumped off the pots. Any suggestionsfor a better fit? Bentonite?

My clay body is an APGreen based stoneware with no added ironand lightened up with some EPK, It has some pyrophillite grog fromCedar Heights, and some fine silica sand. Clay body used by MakenzieSmith at TAMUCC workshop 1995. The firing was done in oxidation. Someof my students had some darker clays in the kiln and reduction givesa form of boredom brown to them. As the kiln was cone 9 ish I startedto spray in the 1 gallon of water with 5 pounds of soda ash(approximate). A nice variety of residual soda effects resulted withorange peel on some rims and dry surfaces where pots were tightlystacked. When the hot spot in the kiln showed a little warping of thepots the kiln was turned off. The firing from dull red heat tookabout 16 hours. It could have been done quicker, but there werenumerous orifice adjustments and I like to go slow in a new kiln. Ido my best to have the kiln going slower than 1 cone per hour abovecone 8. I think it produces more lively glaze surfaces. submitted by:Louis Katz e-mail: lkatz@falcon.tamucc.eduGlaze name: Slip McKenzie's Yellow for SodaCone: 9-10Color: YellowTesting: Surface: unglazedFiring: Salt - SodaGlaze type: SlipTransparency: OpaqueRecipe:Nepheline syenite 31.60Ball clay 63.20Flint 5.30Zircopax Plus 5.30Titanium dioxide 7.00Comments:From McKenzie Smith, who says, "She's a honey in soda Not sure about porcelain buton stoneware it sure is nice."Glaze name: slip Mills BisqueCone: 8 - 10Color: white as baseTesting: Surface: slip or engobeFiring: Glaze type: SlipRecipe:Calcined kaolin 25.00Ball clay 25.00Potash feldspar 45.00Ferro frit 3124 5.00Comments:originally specified Calcium Borate Frit - almost any calcium boronfrit should work.

My experience with copper red is that whatmatters most is to begin reduction at cone 012 fairly heavy and thengo into moderate reduction after cone 05 drops. Continue moderate tolight reduction until cone 10 then a brief oxidation peroid of about10 minutes. If you over reduce it will be liver brown and underreduced will be celadon. One solution to a problem (uneven, spottyreduction and under reduced)we had was to turn down the gas and air.To slow it down and reduce at the above schedule. We were firing inan Alpine updraft with blowers and just running the same schedule asthe people who fired before us. (It was a community center). Theywere firing at 4 pounds pressure (natural gas) with the blowers at70. Something like that. But we reduced the gas and the air and thefiring was 100% better. No more spotty reduction or unreduced pots.(I kind of miss those unwanted interesting results though.) submittedby: John Britt e-mail: claydude@erinet.comGlaze name: Spodumene 1 V.C.Cone: 9 - 10Color: Buff to brownTesting: UntestedSurface: Smooth MattFiring: ReductionGlaze type: Ca Mg AlMattRecipe:Custer spar 30.00EPK 24.00Spodumene 20.00Dolomite 22.00Whiting 4.00Zircopax 6.00Comments:Similar to T.S.

Works well with PenlandPurple overlapped as a "chun". Must be fired to hard ^10 for colour to develop - at 9 it is boringbrown. Use 1/4 to 1/2% macaloid as as suspender*How long have you been using this glaze? Over 7 years*Where is it used? My studio*Where did this recipe come from? CM compilation of glazes. Sorry, date unknown, but older than 10years.*What do you like most about this glaze? Consistency - apply thickly and it stays put. Good for tableware.*Is this glaze reliable? ABSOLUTELY*Does this glaze tend to craze/crawl/pinhole/etc.? Rub any pinholes on dry glaze to avoid pinholing in final product.Wear gloves as this glaze will stain your hands - and your clothing.*How do different firing temperatures/atmospheres affect the glaze? Will fire to ^9 (gets glossy) but the colour is awful! Firing to ^10at 4 o'clock for best results.*How does the glaze behave on different clay bodies? Have used on 3 different clay bodies with identical results.*What consistency should the glaze be for pouring/dipping? Medium thick*How thickly should the glaze be applied to the pot? Medium thick - if applied thinly, you can get some red flashes - butunless clay is extremely smooth (non-stoneware) the end product isnon-functional.*How does this glaze interact with other glazes? Overlapping with Penland opal gives a wonderful "chun" effect in ox.*What is your kiln type and size? PSH CRT 180 - 6.5 cubic ft.*How do you typically fire? I "candle" overnight. 20-24 hours depending on electricity demands.*Do you experience problems with the raw glaze? Rapid settling!! I use .25 - .5% macaloid as a suspender - or itbecomes a cement lump. Also, takes a long time to dry. Be patient!*What is your water pH? I use R/O water*GlazeBase recipe* Submitted by: Sam Cuttell - alias the cat lady (scuttell@wwdc.com) Ice Cream Flavor: Mowie Cowie ------------------------------------------------------------------------Glaze name: TenmokuCone: 9Color: brown to blackTesting: UntestedSurface: shiny, glossyFiring: reductionRecipe:Custer feldspar 56.00Silica 20.50Whiting 16.00Ball clay 7.50Red iron oxide 8.00Bentonite 2.16Comments:This is a fluid but not necessarily runny glaze.

I have used it over colored slip, with sgraffito into theslip and with oxides and stains brushed over it and the decorationsdon't move. This glaze can be brought to the VERY edge of the footwithout moving. I use it inside of all my functional work and whendecorating with colored slips I use it over the whole surface of thepot. It is an excellent glaze that will always perform well especiallywhen you are in a hurry to get things fired. No surprises. Food-safe.*Variations: Can add 1/4 % Copper Carbonate for Light Green in Oxidation ^9-10firing.*How long have you been using this glaze? Almost 20 years*Where is it used? In my studio*Where did this recipe come from? I got this recipe from Kieth Campbell from Ontario, Canada butbelieve that it is an Alfred Univ. glaze originally*What do you like most about this glaze? There are no surprises and I can count on it every time. Its foodsafe.*Is this glaze reliable? Very*Does this glaze tend to craze/crawl/pinhole/etc.? Crazes if applied TOO THICK.*How do different firing temperatures/atmospheres affect the glaze? Electric/Oxidation or Gas fired/Reduction or neutral fire are allequally as good.*How does the glaze behave on different clay bodies? On porcelain and white stoneware it is clear white. On buff and orred bodies it goes somewhat grey because of the iron in the clays.Very pleasent on all clays. I have tested and used on all the aboveclays.*What consistency should the glaze be for pouring/dipping? The consistancy of my glazes is like homo milk. The normalconsistancy. I dip to the count of 5 - 10.*How thickly should the glaze be applied to the pot? Normal. I spray this glaze as well to 1/16th of an inch or better.*How does this glaze interact with other glazes? I like it the way it is for my work. Test your glazes and see whathappens. I have sprayed other glazes on rims etc. and all worked fine.*What is your kiln type and size? 30 cu.ft. downdraft gas kiln.*How do you typically fire? Heating...pilots (4) on over night or at least a 9 hour period.Burners (4) on low over night or till cone 07 is down. Turn up theburners to 1/2 way mid. reduce kiln for 30 to 45 mins. depending onthe weather. Cut the reduction (open dampers to almost open and alight reduction till cone 10 falls. Clear kiln, shut off and seal. Slow 36 hour cool before cracking the door and work comes out inabout 48 hours.*Do you experience problems with the raw glaze? NO....this glaze can be stirred easily even after 8 weeks of non useand stays stirred for long periods of time while glazing. I make alarge green garbage pail of my well used glazes and they last me fora yr. or more. No smells etc.*What is your water pH? City water.*Any other comments?

I'll continue testingand reporting as the winter DRAGS on. All the glazes were tested on#900 Miller clay which is a toasty ^10 stoneware. One side of thetest tile was brushed with a thick coating of Cynthia Bringle'swet/dry white slip. Each glaze was dipped in three thicknesses on aheavily textured tile. All tiles were fired to a (hard)^9 (10tipping)reduction firing. 1 hr. Body reduction at ^08 and 1 hr. glazereduction at ^9 then a quick reox. before shutdown. Any time potashor Custer spar is called for, I used G-200. All ball clay is OM-4 .Many glazes I substituted 75% of the amount of Barium with Strontium.All kaolin is EPK.

Hum!*How long have you been using this glaze? 3years*Where is it used? Studio*Where did this recipe come from? From our own experimentation using the base recipe of our glazenamed Mag as a starting point.*What do you like most about this glaze? The color is very appealing and conservative-like. The surface issemi-gloss with a few speckles and nice to the touch; a very smoothsurface.*Is this glaze reliable? Yes*Does this glaze tend to craze/crawl/pinhole/etc.? No surface flaws.*How do different firing temperatures/atmospheres affect the glaze? Not tested.*How does the glaze behave on different clay bodies? Well.*What consistency should the glaze be for pouring/dipping? Medium*How thickly should the glaze be applied to the pot? Medium*How does this glaze interact with other glazes? Not tested*What is your kiln type and size? Downdraft, propane and atmospheric,60 cubic feet.*How do you typically fire? Oxidation until clay reduction at cone 08, then a light reductionincreasing with time until the final and total reduction of 20minutes followed by a 20 minute period of reoxidation*Do you experience problems with the raw glaze? No*What is your water pH? 7.2*Any other comments?

ALberta slip: At cone 9 Alberta byitself it makes a rich chocolate brown. It's too refractory to workat cone 6 by itself, I was told, so I didn't test it.I added 30%Gerstley borate which was the wrong thing to do, as Alberta is veryglassy to begin with, but I had intended to test at cone 6 as well soI tested for both 6 and 9. I didn't really like the result at cone 6with the gerstley, as it was a frosty transparent olive green (atcone 9 it was a RUNNY transparent olive green. Adding Manganese orcobalt to the Alberta slip would probably give a really nice black.What I left out in making this one was Gerstley 10 (Rob usesColemanite), but what I ended up with was a stony black with verytiny brown specks. Tends to crawl if too thick. Rob's recipe wasgreat too, and that one SHOULD be thick, he says.

(There's thatingredient again, I haven't tried the .75 Strontium Carb actor butdon't think it would make much difference, if you try it I'd like toknow the results) The following glaze meets all your specs except theone about crazing. It's a good glaze that I formulated in my CeramicsI class at University of Central Oklahoma way back there. It is verydependable, doesn't run, you can use a brush over it or under it(with a bit of understandable muting), colors stay in place, it'sglossy, I use it in reduction but in oxidation it loses a bit ofcharacter due to the really white look, You can use it as a base forwax resist with glazes or oxides over. It's the only glaze I've usedcontinually for the past 30 years and on many different bodies. Ilike it and like what it does. If you try it I hope that you like ittoo! Enjoy>>>>>>>>>>> PS...Take Rhodes 32, color it with 1% cobaltoxide and 4% red iron, apply it over this glaze and get a really neatsemi-mat blue. The white sort of bubbles through the blue and it'spretty.

The phosphorus contributes anumber of qualifies to the glaze. It is a glass-former (like the silica), but thephosphorus and silica don't like to mix together (sort of like oil and water).This means that in the firing, the phosphorus tends to separate out and form acloudy, slightly opalescent milkiness that I find very interesting. It also has astrong tendency to re-oxidize colorants in a glaze, which can result in unusual,vivid colors that have the richness of reduction firing, combined with theintensity of oxidation colors. A side effect of the phosphorus is that the glazenow resists going matte. It will if pushed?that is, if the cooling is slow enough,or if the piece is refired in a bisque kiln to allow enough time for the mattingcrystals to grow. Otherwise, it is a glossy glaze. The next step (after coming upwith the base glaze) was to try out all the common glaze colorants and see whatthey did in this glaze. The results are fascinating, and many are beautiful. I'mcurrently in the process of developing more complex colors involving multipleoxides, and I'll pass those along in a future column.If you've ever mixed a tomato red glaze, you'll notice that it always includes asource of magnesium (such as talc or dolomite) and either natural or syntheticbone ash (a source of phosphorus). Together with iron and the other components,these create iron crystals, and push them into an oxidized state. As I suspectedit would, Pete's CIA produces a bright tomato red with 7 or 8% red iron oxide. Asthe amount of iron increases to 10 or 11%, the glaze becomes quite crystalline,but just a bit more brown. The red can be made brighter by refiring it (after theglaze firing) in a bisque firing, or in any low-fire oxidation firing.2 Manganesedioxide makes a beautiful yellow (really!) in small percentages, becoming a creamyred-amber at higher percentages. Copper carbonate, which normally wants to turn apink or red color in reduction, instead produces light blue-green to emeraldgreen. It works from 1 to 9%. Titanium dioxide or ruffle produce very nicebreaking and mottling, working best at 4 and 5%. The effect shows up best onstoneware, but also works well on porcelain with the addition of a small amount ofanother oxide (iron or copper, for instance) in addition to the titania. Tin oxideproduces white at smaller percent-ages, which begins to break rust on edges (evenon porcelain) as it nears 10%, with very pronounced cream and orange colors pro-duced on stoneware at 10% and 12%. Like the iron colors I mentioned above, it willbecome more orange when refired in a bisque or other low-fire oxidation firing.Frankly, I thought the results from cobalt and chrome were very boring, but thatmight be my taste in colors. Cobalt produced pasty, pastel blues. Chrome was nicein very tiny amounts?0.3% made a nice, very light blue-green, but larger amountsproduced dull greenish browns. Please keep in mind that this is a new glaze, and Idon't have extensive experience with it. I've used it (in several colorvariations) in a half dozen or so firings, and it is very promising, but I haveyet to work out all the bugs of application and firing.Glaze name: White PVCone: 8 - 10Color: WhiteTesting: Surface: shiny glossyFiring: Transparency: OpaqueRecipe:Plastic vitrox 50.00Colemanite 50.00Zircopax 15.00Comments:a friend of mine used only this glaze in a lamp factory for years andfired to cone 10. bob chance <chance_bob/furman@furman.edu>Glaze name: White Satin Matt OriellyCone: 9 - 10Color: WhiteTesting: Surface: SatinFiring: Ox. or Red.Glaze type: Magnesium mattTransparency: OpaqueSource: Val Cushing VC ed. via GlazeBaseRecipe:Custer feldspar 56.00Barium carbonate 2.00Dolomite 8.00Whiting 10.00EPK 6.00Zinc oxide 4.00Petalite 3.00Flint 11.00Zircopax 6.00Comments:This glaze comes from Kansas City.
