Mayco's Stoneware Glazes have been formulated for mid-range (cone 4/6) and high fired (cone 9/10) clay bodies. Fired finishes include variegating gloss and matte. These 22 glazes provide consistent and reliable results and do not run during the firing process making them friendly to the user and the kiln. Try them at various temperatures and in both reduction and oxidation for extraordinary looks. We have done extensive testing using popular clay bodies sold in the market to insure compatibility. The Stoneware Glazes are sold in squatty, wide-mouthed pints.
