Abstract

A composition comprises a mixture of lead oxide, boric acid, and alkaline carbonates such as those of sodium, potassium and p barium, to which may be added a small amount of cryolite. The mixture may be fused, run into cold water and thereby granulated, ground into a fine powder, mixed with finely ground mica of about 200 mesh and a small amount of water, and moulded to give the final composition. Alternatively, a mixture of lead oxide and boric acid may be fused and run into cold water, the cooled product being ground to a fine powder and mixed with a powder of cryolite, boric acid and alkaline carbonates and with powdered mica, a small amount of water being added and the composition being formed by moulding.
