"* * IRON OXIDE PIGMENTS. [Par. 55, act of 1913.] GENERAL INFORMATION. Spanish brown, venetian red, Indian red, and colcothar or oxide of iron, not specially provided for in this section, 10 per centum ad valorem." DESCRIPTION. The above provision covers a variety of brown and red paint pigments both natural and artificial, whose colors are due primarily to iron oxides or iron hydroxides. The distinction in the pigment industry, however, between iron oxides of natural origin and those obtained artificially is not sharp. Of these pigments those of the red shade are the more important. The nomenclature of these red pigments is involved and the names are descriptive of the shade rather than of origin, method of production, or chemical composition. Venetian red is a term loosely applied to a variety of the red iron oxide pigments, varying in chemical composition. The only distinction the name implies is light red pigment in contrast to darker iron oxide pigments, chiefly Indian red. Some writers state that thoducshould be restricted to pigments composed of a mixture of posits in and calcium sulphate, produced by neutralizing pickling 'ces practilime and calcining the residue. Under this later dom a deposit reds contain 20 to 40 per cent of iron oxide (Fe,O cent of calcium sulphate (CaSO,). On the other s, p. 13). |
