Plainsman H555 Cone 8-11 Light Grey Ceramic Clay Body, 20 kg

Plainsman H555 Cone 8-11 Light Grey Ceramic Clay Body, 20 kg

High temperature, smooth, functional, medium plastic, vitreous, light grey-buff burning body made from a mix of refined and clean native clays for reduction and oxidation fired functional stoneware. H555 is a 50:50 blend of our native materials (like those used in H550) and of refined industrial minerals (like ball clay, kaolin, feldspar, silica). It thus features some of the robust drying and working properties of the former while also displaying the more refined and vitreous fired character of the latter.
H555 is one of Plainsman's most pleasant throwing bodies. Although smooth and fine, it is not as slick as bodies made entirely of refined materials. It dries relatively fast and has very high green strength.

H555 fires to a pleasant light grey-buff in reduction and buff-white in oxidation. It is semi-vitreous (burns to about 1% porosity at cone 10). It burns significantly whiter than H550 (our buff burning native stoneware) and the speckle population and size is much lower. By cone 7 porosity is about 4% so we do not recommend this body for middle temperature functional ware.

H555 does not bleed iron or interfere with glaze melts and thus encourages clean results. However if you use earthtone glazes that are at their best on iron or speckled bodies, consider trying H550 or H443. If you use white or transparent glazes there will be some scattered small back speckles, especially if the glaze cover is thin.

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.
