Grain′ing.
1. (Leather-manufacture.) a. The process of rubbing leather with a board to raise the grain. The leather having been shaved to a thickness at the beam, and daubed, is hung up to dry, and is then folded, grain side in, and rubbed on the flesh side with a pommel or crippler to give the leather a granular appearance and render it supple. See Crippler.
The hide is then extended and rubbed on the grain side. This is termed bruising.
b. A process for giving markings to a surface of leather to imitate the wrinkled appearance of morocco, hog-skin, and some other leathers.
2. (Painting.) The imitation of the natural grain of wood by means of tools. Combs, brushes, and the corner of a folded rag, are used in making the various patterns.
3.(Lithography.) A mode of giving a certain texture to the face of a stone. One stone is laid upon another with a quantity of sifted sand of a given fineness, and, by a peculiar oscillation and gradual progression, the surface is cut into a set of fine prominences more or less deep and distant, according to the character of the work to be placed upon the stone.
