I know Mel is not saying to add red art to a high fire stoneware clay  
but I'm concerned that some will think that is a good idea.

If you want a body with lots of cristobalite adding red art is an  
excellent way to get that.

Making a dark high fire stoneware body is not easy. Keep in mind you  
will need at east 10% KNaO and best to not have any fine silica.

If anyone is interested in reading Peter Sohngen's article on how to  
avoid cristobalite in high fire stoneware bodies - let me know and  
I'll tell you where to get it.
