I don't know how you do it but each time I've tired the final result is cracked. I'm firing at 1000 dph from cold start to 1650 and holding for 60 minutes. Then I flash to 1500 and hold for 60 minutes. Then flash again to 960 and hold for 2.5 hours. From there I bring it down to 760 at the rate of 200/hr and hold for 30 then down to room temp. I know the first time I did it the glass stuck to the saucer I was melting into. I guess I didn't use enough kiln wash. the second time I tried kiln wash (6 layers), then thinfire cut to the shape of the saucer then a clear disk. This time it only broke in one place not like the other one that was in 100 pieces. So I'm still at a loss.... Would you mind sharing your firing schedule with me?
