Of the bronze or solitaire style by mandarin ing

—The mandarin ing mixture, is 1 gallon of nitric acid, of 1·17 spec. grav.; mixed with 3 pints of solution of nitrate of iron, of spec. grav. 1·65. If the quantity of nitrate of iron be increased, a darker tint will be obtained. The temperature of the mixture should be 94° F. The pieces, after mandarin ing, are let fall into water, and steeped for an hour. In order to raise the bronze, and clear away the fat resist, the goods must be boiled in a bath of soap and soda, as described for orange. 1. Bronze ground, with white figures. (1.) Print on the fat resist; (2.) dip in the blue vat, and dry; (3.) pad in a decoction of logwood, of 4 libs. per gallon; dry, taking care to turn over the selvages; (4.) mandarine, and steep in water for an hour; (5.) cleanse, and pa through soap. 2. Bronze ground, with blue figures. (1.) Dip in the blue vat, and dry; (2.) print-on the fat resist; (3.) pad in the above decoction of logwood, and dry; (4.) mandarine, and steep an hour; (5.) cleanse, and brighten. 3. Bronze ground, with white and blue. (1.) Print-on the fat resist; (2.) dip in the blue vat, and dry; (3.) ground-in the fat resist; (4.) pad in the logwood liquor, and dry; (5.) mandarine, and steep for an hour; (6.) cleanse, and give the brightening boil with soap. This style of manufacture may be executed on chalys; and is capable of producing beautiful effects, which will in vain be sought for by other means. With silks, advantage may be derived from various metallic solutions which po e the property of staining animal substances; among which are nitrate of silver, nitrate of mercury, and muriate of iron. The solutions of these salts may be thickened with gum, and printed-on.
