Does this mean most of you think that the warping issues have more to do with my methods than my firing schedule being above the clays intended cone?
Jim - have any porcelain recommendations for cone 7? The only ones that I could find were cone 5-6 and cone 8-10 - clay makers don't seem to be able to count well, because they completely forgot about 7 />
Thank you to everyone for your help
I'd recommend staying with Frost 5 for cone 7. Try what Chris and others suggested. Frost is so beautiful that it is worth the effort to make it work. It is at its best at 6 1/2 to 7. Test first because it may be a little high for what you make and, unfortunately, some batches of Frost aren't as good as others. Several years ago I tested a lot of cone 6 and cone 10 porcelains but decided that Frost 5 for cone 6 and Southern Ice and Frost 10 for cone 11-12 woodfire were the best and have forgotten most of the others. I rememeber Mile Hi's (in Denver) Aspen was a runner up. One that I didn't test but looks good in the 7th post to the following thread http://ceramicartsda...__fromsearch__1 is Tacoma Clay Arts NZ6.
BTW, I visited your profile gallery which led me to your Etsy site. You're tiles are wonderful!
That's so kind Jim, you just made my day!!
