Dissolve one ounce of seedlac, and half an ounce of stick-lac in a quart of the best alcohol. For this purpose the seedlac should be first pulverized, and being well mixed with the alcohol, the whole, including the stick-lac, may be put into a glass bottle or flask, and suspended near a fire, or set on a stove where it will be kept warm for 24 hours, during which lime it may be occasionally shaken, or stirred up with a rod. Afterward the solution may be strained through a close flannel, when it will be ready for use. The stick-lac may be omitted, unless an orange tinge is required; or a little of the tincture of red saunders may be substituted in place of it. When this is applied, the work must be warmed as much as the hand can bear, and the lacquer is to be quickly laid on, with a camel-hair brush.
