Mayco formulated their new line of stoneware glazes for mid-range (cone 4-6) and highfire (cone 9-10) clay bodies. Fired finishes include gloss, variegating gloss and matte. These glazes provide consistent and reliable results, and do not run during the firing process. They're friendly for both you and your kiln! Try them at various temperatures and in both oxidation and reduction for great color looks.
