Very well endowed with elements. From the back view you can see how simple the wiring is on a kiln like this.
Are you a potter that depends on glazes made by others? Do you have your ware fired in someone else's kiln? Cannot mix clay body tests? Then the evolution of the quality and aesthetics of your work is being stunted. This mug is a good example of why. This is G3933, made by adding iron, rutile and tin to a 75:25 blend of our base matte and glossy glazes. It is crawling at a few sharp angles of the incised decoration, which means it needs a little CMC gum. I need to switch to an 80:20 blend for more matteness. Third, our red-burning body gives better color at cone 5, I need to test this glaze in the C5DHSC slow cool firing schedule. Finally, I would like the glaze a little darker so I will test increases in the rutile and iron. All of these changes are on my radar because I have my own test kiln and an account at insight-live.com to document them.
A test kiln is a must for all potters and small manufacturers, even serious hobbyists. Here is why.
