I’. having a problem with kiln wash also. I don’t know what brand it is but it sticks to the back of my jewelry. I fire fast to 1425 for 10 minutes and then do a fast cool. Should I fire up slower? or cool down slower? I mix the kiln wash 4:1 which was what I was told when I bought my kiln. It worked great the first time but I’ve been having trouble ever since. I am just firing small pieces right now and I have to take a brillo pad to the back of my pieces to get the kiln wash off. I would love to start firing bigger pieces but want to work through this problem first. Any suggestions?
