(1 lb.) Mordant with 2-1/2 ozs. Copper Sulphate. Dye with 2 ozs. to 4 ozs. Madder according to depth of colour required. For yellow brown add a small quantity of fustic (1/4 oz. to the lb.)
(4) RED BROWN
Mordant wool with 3% Chrome (see p. [9]), wash well and dye with 5 to 8 ozs. madder, bringing slowly to the boil, and boil for 1 hour.
Various shades of brownish red can be got by a mixture of madder, fustic and logwood with a Chrome mordant in varying proportions such as 28 per cent Madder, 12 per cent Fustic, 1 per cent Logwood for a brownish claret. 5 per cent Madder, 4 per cent Fustic, 1/2 per cent Logwood for tan.
BRAZIL WOODS
Various leguminous trees, including lima, sapan and peach wood, dye red with alum and tartar, and a purplish slate colour with bichromate of potash. Some old dyers use Brazil wood to heighten the red of madder.
CAMWOOD, BARWOOD, SANDALWOOD, or SANDERSWOOD, are chiefly used in wool dyeing, with other dye woods (such as Old Fustic, and logwood) for browns. They dye good but fugitive red with bichromate of potash, or alum.
