Abstract
702. Seemen, E. von. Jan. 11, 1907, [date applied for under Section 91 of Patents &c. Act, 1907]. Pottery.-Refractory, ceramic, and abrasive products are obtained by fusing natural earths such as bauxite, potter's clay, &c., preferably in the electric furnace, in the presence of sufficient quantities of free oxygen, or with substances, such as saltpetre or manganese dioxide, that yield oxygen. The oxides present are consequently not reduced while the carbon is burnt. Coloured products are obtained by adding suitable metallic oxides to the fused mass. Basic material, such as magnesia, is added to neutralize the silica when it constitutes less than 15 per cent of the whole mass. To raw material containing more than 15 per cent of silica, more silica is added until the product has the composition of ideal Bischoff clay which is composed of one molecule of alumina and one molecule of silica.
