This term is applied to various greasy compounds employed by curriers and shoemakers for softening and preserving leather.
1. Cuttings of sheepskins boiled in cod-oil. Said to be used by curriers.
2. Black resin, 2 oz.; tallow, 1 lb.; crude cod-oil or train-oh, 1 gallon. Boil until the tallow and resin are thoroughly dissolved and mixed.
3. Any good fish-oil or tallow.
The leather or hides to be greased are first moistened; and having been rubbed with the greasy matter are dried in heated rooms, so that the hides, by actually combining with the fatty materials, become, as it were, tanned and tawed at the same time. In the case of hides, therefore, the greasing is not simply an operation of dressing, but in reality a second tanning (technically tawing) process. - Wagner.
