H-555

High temperature, smooth, functional, medium plastic, vitreous, body for reduction and oxidation fired functional stoneware. H555 is a 50:50 blend of native materials 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.
