The tops of library tables, etc. are usually covered with Morocco leather, and ornamented with a gilt border, and are usually sent to the bookbinder for that purpose. The method by which they perform it is as follows: - They first go over that part intended to be gilt with a sponge dipped in the glare of eggs, which is the whites beaten up to a froth, and left to settle; and the longer made or older it is, so much the better; then being provided with a brass roller, on the edge of which the pattern is engraved and fixed as a wheel in a handle, they place it before the fire till heated, so that, by applying a wetted finger, it will just hiss; while it is heating, rub the part with an oiled rag, or clean tallow, where the pattern is intended to be, and lay strips of gold on it. pressing it down with cotton: then with a steady hand run the roller along the edge of the leather, and wipe the superfluous gold off with an oiled rag, and the gold will adhere in those parts where the impression of the roller has been, and the rest will rub off with the oiled rag.
