Abstract

20,070. Thom, T. M. Oct. 4. Stone, artificial.-Relates to the artificial production of building-stones having the exact characteristics of the natural articles, whether they be of compact, magnesian, or oolitic origin. The waste debris of limestone rock, such as Portland or Bath stone, is crushed and screened so as to obtain the grains in their original condition, or, in the case of homogeneous limestones such as the magnesian, the raw material is ground to the degree of fineness exhibited in the natural stone, and the material so obtained is thoroughly mixed with a quantity of lime and slaked. The mixture is then pressed in moulds under a pressure of from “ to ¢ ton to the square inch, dried in a hot chamber, and finally carbonated by a process similar to that described in Specification No. 13,467, A.D. 1900, but in which a much lower pressure is employed. Iron oxide or carbonate may be added to the stone for the purpose of colouring it.
