  • than any other material. Leather tanned with Chestnut Extract possesses high permanence being closely allied to the pure oak bark tannage. Champion chestnut extracts are produced in four grades, each of which is made available in either liquid or powdered form. These are designated as Standard, Light Standard, Bludtan and Melotan. Standard Extract is used for the tanning of heavy leather. It is also valuable as a re tanning agent for chrome tanned leather. In heavy leather, the glucoside of chestnut extract contributes the excellent qualities of weight, solidity and resistance to water, because of its natural acidity from its fermentable bodies. Light Standard extract offers the added advantage of use for tannages where lighter color is important. Bludtan, as its name implies, is decolorized with blood albumen. In this process the heavier and more insoluble tannins, as well as the darker coloring matters, are precipitated, producing a solution of mellow original tannin having the clearness of old wine. This grade is suitable for tannages which require a light color, or a mellow piece of leather. In either the liquid or powdered form it readily blends with any other tanning material. The powdered form dissolves in either hot water or hot liquid, does not lose any of its good qualities, and has the added advantage of saving freight cost. Melotan is of benefit to the tanner using pickled skins, such as sheep, calf, 8 pig, or even pickled splits. It is a special extract of the pyrogallol group and is produced in both liquid and powdered form. Besides being used alone as a straight tannage, or as a retannage for chrome tanned leathers, it is a fine acid mordant for use with basic dye- stuffs. Melotan can be substituted in any tanning process where quebracho, sumac or gambier are used. It produces a tight plump leather with full flank, excellent break and good tensile strength and will not turn red when exposed to sunlight. To provide the tanning industry with the greatest benefit from the purity and uniformity of Champion extracts the manufacturing processes are under the constant supervision of Champion's large technical control laboratory and well developed chemical production organization. The Champion extract plant is the largest single unit in the industry. Its combination with extensive pulp and paper making facilities makes available to its production of extract the highest degree of technical skill and protection to future production by a well organized research program. The maintenance of operation for the manufacture of extract by the Champion mills is assured for a maximum period of time by the availability of plentiful sources of raw material, and an organization that has the strength and power to continue as a reliable source for high value in all of its products.
