COURT PLASTER

is a considerable object of manufacture. It is made as follows: Black silk is strained and brushed over ten or twelve times with the following preparation:—Di olve 1 ⁄ 2 an ounce of balsam of benzoin in 6 ounces of rectified spirits of wine; and in a separate ve el di olve 1 ounce of isingla in as little water as may be. Strain each solution, mix them, and let the mixture rest, so that any undi olved parts may subside; when the clear liquid is cold it will form a jelly, which must be warmed before it is applied to the silk. When the silk coated with it is quite dry, it must be finished off with a coat of a solution of 4 ounces of China turpentine in 6 ounces of tincture of benzoin, to prevent its cracking.
