Plainsman H570 Cone 8-10 Grey-White Ceramic Clay Body, 4 lb

Plainsman H570 Cone 8-10 Grey-White Ceramic Clay Body, 4 lb

A high temperature, smooth, plastic, semi-vitreous, white to grey-white burning, ball clay:kaolin body for oxidation and reduction fired functional stoneware. 
H570 is less white and less vitreous than Plainsman's porcelains. But it is better drying, less prone to warping in the kiln, easier to fit glazes to and potentially more consistent (because it utilizes three clays to minimize effects of individual changes). The combination of working and firing properties make it a very good choice for functional ware for the majority of people.

Although H570 does burn white and speck-free, it does not reach zero-porosity at cone 10. However it does fire more dense in reduction than in oxidation. H570 has a fired surface and strength more similar to stoneware than porcelain and is thus better suited to firing conditions that are not totally consistent.

H570 will preserve bright glaze colors without the iron-bleeding problems associated with stonewares.

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.
