    White stoneware clay body with 40% impalpable grog (up to 80 Mesh). Formulated for artistic ceramics, it is ideal for wheel-throwing and modeling smooth pieces with fine details.

Its particular ivory color after firing is much appreciated and provides an excellent ware for glazes and coloring oxides, which develop bright and intense tones. Available in extruded body (moist form).
