COLOURING WOOD-WORK—OILING—SODA—STAINS AND DYES—IVORYING SURFACES—BLACK DYES AND INK.

Carved or any other wood is often dyed, stained, or toned. Sometimes this is done to make one piece or part match with another; or it may be to imitate the effect of age, or to give light woods a colour which will prevent them from showing defects. This is effected in many ways.

Oiling alone is a kind of colouring, for all oiled wood becomes much darker before long. The more frequently it is rubbed in with a pine stick the harder and darker the surface becomes. I have seen walnut tables which had been thus rubbed with a stick or a hard scrubbing brush, until a tea-cup wet with hot water on the outside would make no mark on them. Had they been only softly oiled or painted, or varnished, an indelible stain must have resulted. Care should be taken that the oil is pure, and that no wax has been boiled in it. A table which has had wax on it for a polish will always show marks or stains from hot water.

Soda dissolved in water, and applied to oak with a sponge or brush, will give it a darker tone, which may be increased by several applications. Dark tea with a little alum is also useful, also porter or beer, also a decoction of walnut leaves. In America butternut gives a very rich indelible dye. Let it be carefully observed that in using these, or any other colours, the following rules must be strictly observed. I. Use a sponge or brush and do not apply the dye profusely or pour it on, as you will run great risk of warping the wood, or causing it to split. II. It may be advisable to dry it near a fire, but in this case exercise great care that the heat be not too great. III. When dry, rub the dye off with a rag or soft old newspaper, or chamois skin. Do this very carefully, and do not be disappointed if it seem very light and to have taken but little dye. Apply the dye again, giving it plenty of time to dry between the coatings. Of course this depends on the dyes used, and the degree of colour required.

Stephens’ stains of different kinds, to imitate all kinds of wood, or those of Mander (Oxford Street, London), are very good, and may now be purchased in every town. As a rule, most of these dyes are very strong, and it is therefore necessary to dilute them with water and make several applications, instead of putting on the whole strength at once. The diluted dye is carefully painted over the entire surface with a full flat camel’s hair brush, and a smaller round brush is used in the corners and smaller recesses. After using dyes, and when perfectly dry, the wood should be oiled.

Ammonia. Wood, and especially oak, may be not only stained of a very dark rich colour, giving the effect of age, by washing it carefully with ammonia or spirits of hartshorn, and then exposing it for some time in a chimney, or otherwise to the fumes of smoke, especially of a wood-fire if it be possible. Strong spirits of ammonia, according to Rowe, may be placed in an open vessel and then shut up with the panel in an airtight chamber or box, the wood darkening according to the length of time it is left in. The ammonia may have to be renewed, as it quickly evaporates. For small work a glass shade may be used, or a box can be made with a glass lid, and after the panel and saucer of ammonia have been placed inside, the crevices can be pasted over with brown paper. When the depth of colour is obtained, which can be seen through the glass, the panel can be taken out. The wood must be so placed that the ammonia can pass quite round the parts which require darkening. But for ordinary purposes, it will be found quite sufficient to apply strong ammonia with a brush or sponge, and expose it to smoke.

Umber. Common powdered umber, which is used by the house painter, is much preferable to the Swiss brown liquid stain to produce an antique brown appearance. The Swiss dye is entirely too rich and uniform, making everything exactly alike, or similar to chocolate. But the umber must be properly applied. Mix it with beer or porter; strong coffee is also very good; and apply it with a brush. When dry rub it very carefully, clean, and apply it again. If it be desirable to make the wood very dark, add lamp-black to the dye, mixing and shaking it very thoroughly. But always let the first applications be of umber alone. By adding the lamp-black one can darken the wood almost to blackness, and if it be very carefully done, and not in a hurry, and exposed at intervals to smoke in a warm place, a colour second to none may be thus given.

Paint. Wood which is to be exposed to the air must of course be painted in the ordinary way. But there is another method of applying oil paint which is not so generally known or practised, yet which gives very good results. This consists of rubbing paint with the hand into wood or on plaster of Paris, papier-machÉ, or stone. As it is much thinner than with coats laid on with a brush, it appears more like an innate or natural colour. This was the finger painting of the old Venetian artists. The appearance thus produced, when it is skilfully done, is very different indeed from that of an ordinary coat of paint, and in most cases it is much more attractive.

Ivorying. Take a panel, the pattern may be carved, or even produced in the lowest relief by simply indenting the outline with a wheel or tracer. Any degree of relief will, however, do just as well. Apply a coat of thick ordinary copal varnish. When perfectly dry smooth it with finest glass or emery-paper. Then apply the paint; two or three coats are better than one. See that the last is perfectly smooth. Then work on the dry surface with tracer and stamps, as you would on wood or brass. When finished, take a very small fitch-brush and paint Vandyke brown into all the dots, lines, scratches, and irregularities. Let there be a dark line of brown close to the outline of the pattern. Sometimes the entire ground may be rubbed with brown, allowing an indication or a few dots of white yellow to show here and there. When dry give two coats of retouching varnish (that of SÖhnee FrÈres, No. 19, Rue des Filles du Calvaire, Paris, is specially suited to this work). By using olive, dark and light greens, a beautiful imitation of bronze can be thus obtained. In fact, by studying the effects of colour in many kinds of old objects, we may obtain hints for converting very ordinary wood-carving into beautiful objects.

Bichromate of Potash, diluted with water to the required shade, is a good dark dye, but great care should be taken not to spill a drop of it on the clothing, or to get it on the hands, or even to inhale its fumes, as it is a poison. Apply it with a brush.

Black Dyes. Of late years black dyes have been so much improved that ebony is imitated with holly, hickory, and beech, to absolute perfection. The best way for the carver, as regards these and all kinds of dyes, such as red, yellow, green, etc., is to go to a chemist or colourman, who will obtain them for him. For black the following recipes may be used.

I.

Steep it in a corked bottle for eight days.

II.

Boil down to one half. (Seaton.)

To stain wood, first apply No. II., when nearly dry put on No. I. and then No. II. again. It will occur to the reader that this is really ink, and, in fact, if he cannot get a stain, good common ink applied a few times and well dried will answer quite as well. After it has been thoroughly put on, and quite dry, oil the surface, and rub it well, and it will be found that it will not wash off from any casual application of water. Some of the writing inks now made are intensely black and almost indelible.
