tion of the precipitate, the mass is filter pressed, dried, muflled and processed in the on the market, in that the {covering capacity of the pigment is greatly increased, as well The titanium oxide is peptized or held in as its fastness to light, and ease of working in oils. It is also superior to the so called double strength lithopone made by doubling the zinc sulphide conent, in that it is very neutral to acid vehicles. It is also far superior to other titanium compounds on the market, inasmuch as greater opacities are obtained with a relatively small amount of titanium oxide, than has heretofore been obtained with far greater proportions of titanium oxide, thereby effecting a considerable economy over that of other similar products containing'titanium oxide.

A dense, white, opaque pigment composed of a mixture of Zinc sulfide (30%) and Barium sulfate (70%) with trace amounts of Zinc oxide. Lithopone, first produced in 1874, was called Orr's white. The mixture of the two components is so intimate that it is hard to distinguish microscopically. Lithopone is an inert, transparent pigment which is often used as a filler or as a base for lake pigments. Lithopone was widely used in house paints in the first half of the 20th century. It was also used for some artist grounds, inks and as a filler in Paper, Leather, and Linoleum. Now lithopone has mostly been replaced by Titanium dioxide.
