Staining Wood
AND IVORY.
Yellow. Diluted nitric acid will produce a fine yellow on wood; sometimes it makes a brown, and if used strong, it will be nearly black.
Mahogany Color Is produced by a mixture of madder, Brazil wood, and logwood, dissolved in water and put on hot. The proportions must be varied, according to the tint required.
Black. Brush the wood several times over with a hot decoction of logwood, and then with an iron lacquer; or, if this cannot be had, a strong solution of nut-galls.
