1. Give the goods a mixed mordant of acetate of alumina and acetate of iron, followed by a bath of madder or of madder and fustic. Excess of acetate of alumina turns it on the AMARANTH TINT; the acetate of iron darkens it.
2. First ‘gall’ the goods, then turn them for a short time through the black bath; next give them a mordant of sulphate of copper,
then pass them through a decoction of fustic, afterwards through a bath of madder, and again through the solution of sulphate of copper; drain, dry, rinse well, and finish with a boil in soap and water. This gives a CHESTNUT-BROWN.
3. First give the goods a mordant of alum, then a bath of madder, and next a bath of fustic to which a little green copperas has been added. This gives a CINNAMON-BROWN.
b. For Linen:—This varies little from that commonly employed for cotton.
c. For Silk:—
1. One of the above mordants is followed by a bath made by mixing equal parts of the decoctions of logwood, fustic, and Brazil-wood. The shade may be varied by altering the proportions of the decoctions; Brazil-wood reddening, logwood darkening, and fustic yellowing, the tint.
2. Annotta, 4 oz.; and pearlash, 1 lb.; are dissolved in boiling water, q. s.; the silk is passed through it for two hours, then taken out, and squeezed dry; it is next passed through a mordant of alum, and then through a bath of Brazil-wood, followed by another of logwood to which a little green copperas has been added.
d. For Wool:—
1. Boil the cloth in a mixed mordant of alum, common salt, and water, then dye it in a bath of logwood to which a little green copperas has been added. 2 oz. of alum, and 1 oz. of salt, are required for every lb. of wool.
