15,667. Thom, T. M. July 8. Facing-blocks; slabs. - The face is of ornamental artificial stone or marble and the interior of rough, inexpensive, and light material, the whole being moulded and then hardened by treatment with carbon dioxide. The mould is first lined with a plastic mixture of lime and granular stone, and is then filled with coarse material, such as a mixture of limestone and lime ashes. A core, removable or otherwise, may be inserted. Pressure is applied, and the moulded block is finally carbonated. Slag may be employed in the facing-mixture.
