Plainsman H441G Cone 8-10 White Buff Grogged Ceramic Clay Body, 4 lb

Plainsman H441G Cone 8-10 White Buff Grogged Ceramic Clay Body, 4 lb

High temperature, grogged but fairly smooth, plastic, non-vitreous, white buff burning, native body for reduction fired handbuilding and sculpture. This is Plainman's most refractory body. It is made from 50% of a high coal very white burning plastic fireclay along with 18% grog and a mix of stoneware and ball clays. H441G is good for sculpture and other types of work where forms are subject to warping in the kiln (i.e. overhung, appendages sticking out, shapes lacking strength).

H441G fires much whiter than typical sculpture clays. It does have some soluble salts discoloration on the surface and these enhance textures and contours on unglazed pieces (in reduction firing). If you need a darker firing material, try H440G. Although H441G does throw quite well, we do not recommend it for functional ware because of its refractory nature. MSculp is an alternative. It is more vitreous and has much more larger particle grog.

It is best to fire larger sculptural forms on a thick slab made from the same clay. This slab will absorb the stresses associated with shrinkage and help prevent cracking and warping.

Storage: Protect ceramic clay bodies from direct sunlight, avoiding excessive temperature changes and protect from frost.

Use: It is recommended to test clay body prior to large scale use in order to verify suitability in both the ceramic process (shaping, drying, firing and decoration) and the final application that is expected to be obtained.
