Linoleum. A variety of floor cloth, consisting of oxidized linseed oil combined with ground cork, treated and masticated in the same manner as Kamptulicon (which see), to which it bears a close resemblence. The process of making linoleum was patented in 1863, by F. Walton, who specifies as the most suitable composition for the "body" of linoleum, 4 per cent of oxidized oil, 11/2 per cent of resin, 1/2 cwt. of kaurie gum and coloring matter, mixed together in a steam heated receptacle, and afterwards mixed with an equal weight of ground cork dust, and spread on and pressed into a woven cloth of jute or hemp, between steam heated rollers. The weight required to press the material into the mesh of the cloth is 4,000 pounds to the square inch. The pattern is printed on the surface by means of blocks. Linoleum has the advantage that it is not cold like tiling or oil cloth; it is made in all widths up to 6 yards.
