Horn must be treated in the same manner as bone and ivory for the various colours given under that heading.
1423. Imitation of Tortoisesh.e.l.l.
First steam and then press the horn into proper shapes, and afterwards lay the following mixture on with a small brush, in imitation of the mottle of tortoisesh.e.l.l:--Take equal parts of quicklime and litharge, and mix with strong soap-lees; let this remain until it is thoroughly dry, brush off, and repeat two or three times, if necessary. Such parts as are required to be of a reddish brown should be covered with a mixture of whiting and the stain.
1424. Iron. _Black, for ships' guns, shots, &c._
To one gallon of vinegar add a quarter of a pound of iron rust, let it stand for a week; then add a pound of dry lampblack, and three-quarters of a pound of copperas; stir it up at intervals for a couple of days. Lay five or six coats on the gun, &c., with a sponge, allowing it to dry well between each. Polish with linseed oil and soft woollen rag, and it will look like ebony.

1430. Wood. _Black._
i. Drop a little sulphuric acid into a small quant.i.ty of water, brush over the wood and hold to the fire; it will turn a fine black, and take a good polish.
ii. Take half a gallon of vinegar, an ounce of bruised nut galls, of logwood chips and copperas each half a pound--boil well; add half an ounce of the tincture of sesquichloride of iron, formerly called the muriated tincture and brush on hot.
iii. Use the stain given for ships' guns.
iv. Take half a gallon of vinegar, half a pound of dry lampblack, and three pounds of iron rust, sifted. Mix, and let stand for a week. Lay three coats of this on hot, and then rub with linseed oil, and you will have a fine deep black.
v. Add to the above stain an ounce of nut galls, half a pound of log-wood chips, and a quarter of a pound of copperas; lay on three coats, oil well, and you will have a black stain that will stand any kind of weather, and one that is well suited for ships' combings, &c.
vi. Take a pound of logwood chips, a quarter of a pound of Brazil wood, and boil for an hour and a half in a gallon of water. Brush the wood several times with this decoction while hot. Make a decoction of nut galls by simmering gently, for three or four days, a quarter of a pound of the galls in two quarts of water; give the wood three coats of this, and, while wet, lay on a solution of sulphate of iron (two ounces to a quart), and when dry, oil or varnish.
vii. Give three coats with a solution of copper filings in aquafortis, and repeatedly brush over with the logwood decoction, until the greenness of the copper is destroyed.
viii. Boil half a pound of logwood chips in two quarts of water, add an ounce of pearlash, and apply hot with a brush. Then take two quarts of the logwood decoction, and half an ounce of verdigris, and the same of copperas; strain, and throw in half a pound of iron rust. Brush the work well with this, and oil.
