Has anyone else tried Susan Peterson's flameware claybody? I just mixed
10 lbs of it up last night and threw a smallish bowl-pot on the wheel
with it this morning. I'm excited to try it out. I added some
thickish, cavemanish handles to the top sides of the pot. I'll bisque
and fire it to cone 10, and then just try boiling water and making
ramen in it.
Here's the recipe for the claybody:
Petalite 30%
Spodumene 20%
Fire clay 30%
Ball clay 20%
Should be fun! I've got several other flameware recipes I will be trying
out -- including ones from Robbie Lobell when the pyrophillite arrives
at the ceramic store. It's a special order.
If anyone has any other recipes or recommendations, I'm all ears. I
want to make caveman pots with cave art on them and use them. So fun!

Your constant enthusiasm is wonderful!! But flameware bodies are best
approched w/ caution and serious testing.
