AmateurCeramics Posted December 18, 2021 Report Share Posted December 18, 2021 I recently did a glaze firing to cone 06 and the pieces came out horribly. I am relatively new to firing and was wondering if you could help me figure out what went wrong. I used BMix clay bisque fired to cone 04 then applied the glazes. The glazes used are in the pictures written on a note. I glaze fired to cone 06 and monitored the firing temps and they were as follows (all degrees are in Fahrenheit): Starting temp: 73 2 hours temp: 700 4 hour temp: 1185 6 hour temp: 1560 7 hour temp: 1680 8 hour temp: 1785 Final temp: 1827 at 8.5 hours Any thoughts very much appreciated!!

Chilly Posted December 18, 2021 Report Share Posted December 18, 2021 Hi @AmateurCeramicsand welcome to the forum. Others will chip in and help you more than I can, but first..... 7 minutes ago, AmateurCeramics said: glaze firing to cone 6 7 minutes ago, AmateurCeramics said: glaze fired to cone 06 Your first and third paragraphs contradict. Did you fire to ^6 or ^06? That zero makes a lot of difference. Did you use witness cones to verify the actual cone you fired to? Link to comment Share on other sites More sharing options...
AmateurCeramics Posted December 18, 2021 Author Report Share Posted December 18, 2021 Ah so sorry. Bisque fired to cone 04 and glaze fired to cone 06. Thanks for catching that! Link to comment Share on other sites More sharing options...

Chilly Posted December 18, 2021 Report Share Posted December 18, 2021 Are the glazes Amaco Potter's Choice? If yes, they need firing to ^5 - ^6, much hotter than ^06. Link to comment Share on other sites More sharing options...
