Fancy colored woods for inlaying very much enhance the effect of work of this character. The usual materia] employed for staining white deal and other plain woods to imitate woods of a different texture or superior quality are various decoctions of vegetable matters, such as logwood, Brazil and sandal wood, and tumeric, etc., are used for producing reds, browns and yellow; while various mineral bodies, such as picric acid, permagnate of potash, caustic lime, etc., are used for deepening the color of woods and otherwise altering their character; but none of these materials produce bright, vivid colors, such as blue, golden yellow, green, etc.
Of course, for furniture and woods used in decoration, such vivid colors are out of place, but for inlay work, bright, fancy colors are applicable, and by means of aniline dyes can be produced in an infinite variety of hues. But to produce successful results precautions are necessary, because these dyes act so energetically on all organic structures, such as woods, leather, ivory, etc., as to enable many different shades to be obtained by any particular dye. For example, a very strong solution will produce a coloration so deep and intense as to exhibit a bronzed appear" ance, but any number of successive applications of weaker solutions will not produce such a deep coloration ; on the other hand, if only a very weak solution of the dye be used at first, it is possible to produce any gradation of tones by the subsequent application of successively stronger solutions of the dye, but it must be borne in mind that the strength of the dye first applied, and the temperature at which it is applied, determines the resultant color; consequently, to produce any desired tone, experiments should be first made on small pieces of wood before proceeding to tain the whole of it.
