1st. Bath.—Put 2 oz. Madder into 10 quarts of water, heat up to boiling but do not let it boil. Put in thread and stir well for 1 hour.
2nd. Bath.—Put 3 oz. Madder in 10 quarts of water; treat as in first bath, from which the thread should be taken and put straight into the 2nd. bath. Stir for 1 hour. Soak for 24 hours; wash and dry.
3rd. Bath.—Put 3 oz. Madder in 10 quarts water; repeat the process described for 2nd. bath. The thread should be washed in cold water & lastly in warm water in which a little soft soap has been dissolved. When drying do not wring the skeins as this is likely to make the colour uneven.
There are a few other red dyes of minor importance which should be mentioned.
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. They are not fast colours.
Some old dyers used 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.
RED from LADIES BEDSTRAW.
The crushed roots of this plant are used. Mordant the wool with either alum or bichromate of potash. The red with alum is an orange red, with chrome, a crimson red. Make the dye bath with 30 to 50% of bedstraw roots and boil the mordanted wool in it for an hour.
RED for COTTON.
