All the little colourful ducks in a row. do you know what these are????? Each kiln load needs to have witness cones to be able to "read" the kiln during each firing. Reaching temperature is one thing, but these cones don't lie and will tell me what is going on on an individual kiln or In an individual zone. I use the cone I am firing to in the centre and I flag it with a higher and lower cone just to see if the kiln underfired or over fired. Just one cone won't suffice #diditoverfire #cone6 #pottersofperiscope #pottery #ceramics #process #witnesscones #orton #handmade #putthemineverykiln #canadianceramics #makersgonnamake #creativeprocess
