Steam pink

—A decoction of Brazil-wood with a small quantity of the solution of muriate of tin, called, at Manchester, new tin crystals [15] , and a little nitrate of copper to a ist in fixing the colour; properly thickened, dried, and steamed for not more than 20 minutes, on account of the corrosive action of muriate of tin when the heat is too strong. [15] This preparation is made by adding 3 libs. of sal ammoniac to 1 gallon of solution of tin ( see Scarlet Dye , and Tin ), evaporating, and crystallizing. The sal ammoniac seems to counteract the separation of the tin by peroxidize ment.
