Abstract
In the production of fireproof stones particles of a size below 0.25 mms. are removed from sintered magnesia and the residue pressed, with or without subsequent burning, at a pressure suitable to give a porosity substantially free from capillaries. Preferably, the sintered magnesia has a porosity not exceeding 10 per cent. by volume.
