SIO-2® PRAI - White Stoneware Clay with Impalpable Grog, 4 lb Sample

SIO-2® PRAI - White Stoneware Clay with Impalpable Grog

4 lb (1.8 kg) Sample

PRAI is a 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.

The high content of grog confers an excellent behavior during drying and firing. Its particular ivory color after firing provides an excellent ware for glazes and coloring oxides, which develop bright and intense tones.

PRAI is available in extruded body (moist form).
