2. (White hard.)—a. From gum sandarach (picked), 5 lbs.; camphor, 2 oz.; washed and dried coarsely pounded glass, 3 lbs.; rectified spirit (65 o. p.), 7 quarts; proceed as in making mastic varnish; when strained, add of pure Canada balsam, 1 quart. Very pale, durable, and brilliant.
b. From gum sandarach and gum mastic, of each, picked, 4 oz.; coarsely powdered glass, 8 oz.; rectified spirit, 1 quart; dissolve, and add of pure Strasburg turpentine, 3 oz. Very fine.
3. (Soft brilliant.) From sandarach, 6 oz.; elemi (genuine), 4 oz.; animé, 1 oz.; camphor, 1⁄2 oz.; rectified spirit, 1 quart; as before.
4. (Scented.) To the preceding add some gum benzoin, balsam of Peru, balsam of Tola, oil of lavender, or the essence of musk or ambergris. The first two can only be employed for dark varnishes.
Obs. The above varnishes are chiefly applied to articles of the toilette, as work-boxes, card-cases, &c.; but are also suitable to other articles, whether of paper, wood, linen, or metal, that require a brilliant and quick-drying varnish. They dry almost as soon as applied, and are usually hard enough to polish in 24 hours. They are, however, much less durable, and more liable to crack, than oil varnishes.
