Hi,
I make smoke fired pottery and have always bisque them at a low bisque temperature but I'm looking for alternatives for people that I know do not own a kiln. I'm planning on doing some smoke-fired burnished pottery pieces and I'm wondering what I should start to look for in a clay if I am NOT going to pre-bisque the pieces. Should I look for a clay that contains grog, sand or a combination? If so what should the mesh size be and what percentage should be in the clay? Should it be earthenware or stoneware or does that matter? Would my best bet be for a raku clay? If someone out there only knows the name brand of the clay I could probably look the information up but I only have a couple brands available in my area. I know I could contact them but I would prefer information from people that know about it first hand.
I know that I have to worry about thermal shock and pieces breaking but I do have some ideas on how to remedy that if it does happen. This will be an experimentation in itself, but my thinking is if I start with the best clay for this type of work the breakage should be reduced. Any and all information would be greatly appreciated. Feel free to reply to me directly.
Thanks, Crystal
