Plainsman P300 Cone 4-7 Off-White Ceramic Clay Body, 4 lb

Mid-temperature, medium plastic, vitreous, off-white burning, kaolin-only porcelain.

P300 is a mix of plastic Georgia kaolin, nepheline syenite, 25% silica, raw bentonite (to augment plasicity) and a small amount of talc (for fired maturity control). P300 is not translucent at cone 6. It is the whitest body Plainsman can make without using expensive white plasticizers or overseas kaolins.

P300 is smooth, slick and fine grained. Since it is a kaolin-only porcelain, the pugged material has a distinct feel that many prefer to ball-clay-containing bodies. The added bentonite dramatically improves plasticity (as good or better than M370) and the dry strength is excellent.

P300 fires a little whiter than M370, but not nearly as white as Polar Ice. It is intended to have just a little porosity at cone 6 (for resistance to warping and crazing). It has a fairly high fired shrinkage. To prevent warping, try to make ware of even cross section and avoid profiles prone to the problem.

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.
