Simon Levin's True GritSimon Levin's True Grit, a groggy sculptural stoneware with beautiful flashing in a reduction cooled wood kiln. This is a high fire clay (the bowls in the image are from test firing in KU's wood kiln which often reaches Cone 12). This isn't intended to be used in low fire wood applications, but if you want to try it, we won't stop you. Read a beautiful description of woodfiring directly from Simon Levin's website and in his words.
