6256. Sundell, F. R. A. March 20. Slabs; moulding artificial stone.-Artificial stone slabs and the like are made on a suitable support such as a glass plate, and after removal the face is ground to a substantial extent. A thin layer of stone composition such as that described in Specification No. 7976, A.D. 1903, [Abridgment Class Cements &c.], of the desired ground colour, is applied to the glass, and into this layer is thrown, for example with a paint brush, wet stone masses of different colours, such masses completely or partly penetrating the bottom mass. A layer of marmorit is applied to the upper surface, and dry marmorit is sifted on to absorb moisture. The back surface is scraped away to leave a slab of any required thickness. To the back of this may be applied a piece of soaked fabric such as entrenne, or several pieces in the case of a table top, which unite with the slab on drying, dry marmorit being again sifted on. The slab is removed from the support by raising one corner and injecting water. A substantial thickness is ground off the face of the slab, which may then be polished. By using suitably shaped supports, lists or other shapes may be made.
