I got a bit of glaze bug recently. I am trying to get the no craze celadon. Celadon glaze is traditionally preferred to have the crazing, but I want to try one without. So far, all crazed. Steven Hill's celadon recipe found in the web turned out really nice celadon green, but crazed nicely.

Craze free celadons are really hard. I have a little bit of success by using 10-20% spodumene in place of some of your Custer (or whatever feldspar you use), and by increasing the clay content a bit, which I balance by adding some boron.
Maybe you've already tried this? Anyway first thing I would try is a line blend replacing KNa (in custer) with Lithium (in Spodumene) in your current celadon recipe. it is a bit more complicated that just replacing Custer with Spodumene. I have a copy of Insight which I can use to help you design a good line blend if you like. E-mail me.

Thank you. I will try a line blend with spodumene.
