Thank you very much for your inquiry. The article “Porcelain body for making sulfides.” by Roland Butler in the Independent Glassblower, no. 5, p. 3. states:
Potash feldspar 17.06 oz
Edger's plastic kaolin (EPK) 34.8 oz
Potter's flint 8.0 oz
Colemanite 5.2 oz
Whiting 4.0 oz
Bentonite 2.4 oz
Ball Clay 2.6 oz
"These materials are mixed thoroughly dry and then enough water is added to make a plastic putty. The above quantities will make up about 4-1/2 pounds.
The little pieces molded from this body are air dried and then fired to cone 5 (2200 degrees) in a small kiln.
Of course the pieces should be heated before trying to mount them in the glass. Also simpler models are easier to gather over without including bubbles."
