Wood (To Give A Fine Black Colour To). Steep the wood for two or three days in luke-warm water, in which a little alum has been dissolved; then put a handful of logwood, cut small, into a pint of water, and boil it down to less than half a pint. If you then add a little indigo, the colour will be more beautiful. Spread a layer of this liquor quite hot on your wood, with a pencil, which will give it a violet colour. When it is dry, spread on another layer; dry it again, and give it a third; then boil verdigris at discretion, in its own vinegar, and spread a layer of it on the wood; when it is dry, rub it with a brush, and then with oiled chamois skin. This gives a fine black, and imitates perfectly the colour of ebony.
