I'm curious about what schedule people are using for cone 6 in automatic kilns? I recently bought one, and am trying to fine-tune my firing. Some of my glazes are gloss, some are matte and my studio partner uses Coyote commercial glazes. Do we need a different schedule for each type?

Thanks,

Sylvia

Good question - I like to fire to cone 6 from stone cold in about 6 hours but realistically it takes me about 7-8 to get there. I cut the power, shut everything off but it will be longer than 7-8 hours before farenheit 451 (testing with a twisted piece of newsprint) then I open up the ports, plugs, and prope the lid 1/2 inch open. etc. Glaze and matte is a function of glaze chemistry not maturing point. But since you want to do Coyote's glazes what do they recommend???

That sounds a lot like the schedule I used with my old manual kiln. The Skutt rep gave me a 6 stage schedule for slow cooling to allow tiny crystals to develop for matte glazes, but I was just wondering what other people used. I have no idea what Coyote recommends, since I don't use their glazes myself.

Thanks for the response.

Well there is a school of thought that the bell shaped curve is the best to avoid defects, although there are those who crash cool for other reasons... then there is the peak & soak school, as well as the fire and re-fire people. So much depends on the glazes actually.
