SIO-2® Berlin Grey Stoneware Clay with Impalpable Grog, 27.6 lb

SIO-2® Berlin Grey Stoneware Clay with Impalpable Grog

27.6 lb (12.5 kg)

Berline Grey is a 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. Depending on the firing temperature, it develops an interesting range of greys, from cement to dark grey, which satisfies the most avant-garde trends in artistic ceramics.

Suitable for tableware (food-safe), according to ISO 6486:1999. It is available in extruded body (moist form), in a 27.6 lb. package.
