Excerpt from The Chemistry of Mineral Tannages During the last few years the manufacturers of morocco have made great changes in their output. There is little demand at present for the old styles of sumac tannages, "Brush Kid, " "Pebbles, " &c., , but the newer styles of mineral tannages with a glazed finish are largely called for by shoe manufacturers, and gentlemen in the morocco trade are now striving to supply this demand. Although there are about as many different kinds of Glazed Kid on the market as there are manufacturers, still these may be grouped into five classes. 1. Gambia and Alum Tannage. Many manufacturers are devoting their attention to this with success. The skins are placed in a vat, with a wheel, which contains the tanning liquor, where they are allowed to remain about two days. The tan varies in composition very much, some use most all gambia with a little alum, while others use most all alum with a little gambia. The skins after being tanned are fat liquored, dried out, moistened, shaved, staked, blacked, and finished either dull or glazed. 2. India Tanned Stock cleansed, retanned and finished into glazed kid, this is largely turned out in the vicinity of Boston. 3. Sumac Tanned Stock softened, staked, fat liquored and finished into dull and bright stock. This tannage has been brought to great perfection in Wilmington, Del.
