> I am looking for a Cone 6 vitreous clay body formula for throwing.
I would start with 25% ball clay, 25% kaolin and 50% feldspar.
If this is too vitreous, reduce the feldspar. Use a plastic kaolin
If it is not plastic enough, increase the ball clay and reduce the
If it is not white enough, increase the kaolin, reduce the ball clay
and add a little bentonite to restore plasticity.
If your glazes craze, then add flint and reduce the thermal expansion
of your glazes.
