Kammymckenna Posted December 21, 2019 Report Share Posted December 21, 2019 Has anyone tried it? I searched online and didn't find anything. I have a ^6 celadon glaze I want to use on ^05 bisque. Link to comment Share on other sites More sharing options...
Roberta12 Posted December 21, 2019 Report Share Posted December 21, 2019 Are you going to fire at Cone 6 or 05? Link to comment Share on other sites More sharing options...
neilestrick Posted December 21, 2019 Report Share Posted December 21, 2019 You need your clay and glaze to mature at the same cone. Do not fire earthenware clay to cone 6 or it will melt. Do not fire cone 6 glazes to cone 04 or they won't melt. In general, we bisque to cone 06-04 regardless of the glaze firing temperature. If you bisque hotter than that, the clay will not be porous and it will be difficult to glaze. Link to comment Share on other sites More sharing options...

I have a ^6 celadon glaze I want to use on ^05 bisque. Everything above is spot on! Mid and high fire clay only sinter at low fire temps, they don’t begin to melt into a solid fired clay product. Same with glazes designed for cone six fired to lowfire temperatures. It likely won’t be a decent glass. The only exception I can think of is there are some (not a lot) of glazes that are designed to work from cone 05 through cone six. They generally contain boron to allow them to melt early but are stiff enough to fire to cone six without dripping off your pot. One such commercial glaze is stroke and coat I believe. I mention this because if you are working with low fire clay, there are several glazes out there that are designed to work over a broad range and are available for you to use.
