Hi everyone, Quick question: we use calcite alumina, or alumina calcined (in South Africa) under ware when glaze firing to provide a surface allowing movement to avoid cracking, what name does the rest of the world use? TIA Andrea
Hello, I fired my first glaze kiln (electric) last night and it was finished around 6am this morning. Once the temperature started to go down after it got to temp I turned my kiln off and left everything shut. I have been coming down to check the temperature every so often and I have noticed a very faint crackling noise kind of like Velcro being taken apart or electrical crackling.. All of the glazes are supposed to be guaranteed to fit my clay body (I have friends that work at a distribution center making both clay and glaze). My clay is a buff stoneware that fires between cone 2-7 and I am using Amaco PC cone 5-6, I fired to cone 6. I know what the pinging sounds like when a kiln is opened too hot, but this isn’t a ping noise. I haven’t opened the kiln at all and have left the peep holes shut, could it be cooling too fast still? This is my first time firing a kiln on my own (with instruction from the clay friends). I’m afraid to see what my pieces look like when they’re finally cooled..
