Nancy Hartzenbusch Posted September 17, 2023 Report Share Posted September 17, 2023 So… I bisque fired my pots— Highwater Phoenix clay— to cone 08 as I was planning to Raku them. After bisque firing, I changed my mind and decided to glaze them with regular Amaco glaze suitable for cone 6 firing. Will the low bisque temperature result in my pots exploding or disintegrating in my kiln when I glaze firing them to cone 6??? Quote Link to comment Share on other sites More sharing options...
Min Posted September 17, 2023 Report Share Posted September 17, 2023 Hi Nancy and welcome to the forum! Nope the pots won't explode or disintegrate if you now fire them to cone 6. I don't know how prone to pinhole issues Highwater Phoneix clay is if it's bisqued to cone 08 rather than a hotter cone 06 - 04, might be fine. Are you using the pots for functional ware once fired to cone 6? If this is the clay you are using it has a posted absorption of nearly 4% when fired to cone 6, as it really is a highfire clay so it will be immature at cone 6 and likely to weep without a really well fitting glaze.
