16.—Alcohol, of the highest proof. This is used in laying the gold leaf which is to be burnished.
17.—Japan gold size.
18.—Shellac Varnish, both the brown and the white.
19.—Burnish-size Strainer.
20.—Several Cups, for mixing the different preparations. It is well to have covers for them, as all the preparations should be effectually protected from dust.
21.—A Graduated Glass Measure; one of four ounces capacity is the most useful.
22.—Spoons, for mixing with. The tea size is the best for general use.
II.
The burnish-size should be always kept in a china or earthenware jar. If kept in a tin vessel, its moisture causes the tin to rust, and the deposit caused by the rust is highly injurious to the size. The oil-size may be kept in a tin vessel provided with a cover. When this size is required for use, it should be thoroughly stirred up, as the coloring matter of which it is in part composed, being the heaviest, has a tendency to settle and to leave the pure oil on the surface. Take out only a sufficient quantity for immediate use, as it sets quite rapidly, particularly in warm weather; and do not return any that may be left, back to the original vessel containing the size. Pay no attention to the skin which from time to time forms on the surface, when not in use.
