High Fire Pompeian Ash High Fire (Cone 5-6) Glazes -- LEAD FREE
All colors of the Pompeian Ash series are LEAD FREE.
CL glazes restricted from use K-6 (ASTM D-4236/LHAMA)
Pompeian Ash glazes have a unique formula that produces a wiggly design pattern as they flow on the piece. This series has to be fired to Cone 5-6 in an electric kiln. The result is similar to ash glazes that have to be fired to Cone 10 in reduction. These glazes reduce firing costs and eliminate the exposure to toxic materials that are required with such Cone 10 formulas.
Apply these glazes by brushing or dipping. Taper down the application to one towards the bottom of the piece, to give room for the glaze to run.
Fire with a dry foot, on a kiln shelf which has been well coated with kiln wash. Use stilts or place over a refractory brick to catch any glaze that may overflow. With repeated use of these glazes, you will learn to what extent to taper down to eliminate overflow.
These glazes will work well over stoneware or porcelain clays.
