Black from Logwood.—In the days when our grandmothers made their own ink every one knew how to obtain this dye. Boil the rattan in a decoction of fifty parts of logwood to ten of fustic, for half an hour. Remove the rattan and add four parts of copperas. Return the rattan and boil ten or fifteen minutes. Orange from Annatto.—A bright orange is made from annatto in this way. A short time before it is required for use, it is dissolved by boiling it with a solution of carbonate of soda (washing soda) for twenty minutes. Mordant the rattan with stannous chloride (or tin crystals, which dissolve in a small quantity of water) and dye. |
