Intarsia and Marquetry

The modern French marquetry, though exceedingly clever and beautiful in its use of various woods, errs by want of consideration of the surface to be decorated, the subjects flowing over the surfaces and overflowing the proper boundaries very often; and also sins in using many woods of very slightly different tones and textures, which will almost certainly lose their reciprocal relation in the course of time, and thereby their decorative effect. The ancient intarsias were made of a small number of different woods, and the effect was kept simple; pear, white poplar, oak, walnut, and holly almost exhaust the list; while even Roentgen's work, in which he used a larger number of woods, including some of those foreign trees which Dutch commerce made available for him, has suffered from their changing and fading. I would advise the marqueteur to disregard most of the many foreign woods now in the market, and content himself with simple and well-proved effects for the most part, trusting rather to beauty of design to give distinction to his work than to variety of colour and startling effects of contrast.

It is the fashion at the present day to exhort the designer to found his design upon the study of nature, which is right enough if accompanied by discretion and a feeling for style. In many mouths, however, the exhortation means that the copying of natural forms is advised, and often, if one may judge from the examples which one sees around one, without selection either of subject or form. Now it is obvious that it is sometimes the beauty of form in natural objects which attracts the eye, and sometimes the beauty or strangeness of colours, either in their combination or from the unusual tint. And while the former quality fits the object for translation into ornament, by means of simplification and repetition, the latter is more likely to be the suggestive starting point for the production of something quite different than a factor in a directly-derived composition. Certain forms of flowers and leaves are also suitable for ornament expressed in a certain way, and when this harmony occurs the representation of nature is satisfactory as ornament; but the reverse is very often shown to be the case in work of a more modern type, in which the design is based on the dictum that the copying of natural forms will produce ornament. It is not the copying of natural forms, but the ordering of the spaces, the arranging and balancing of line and mass, and the adaptation of means to ends which produce satisfactory decoration, and in the best Italian intarsias founded upon freely-growing, natural plants this is well shown. The observation of natural growth shown in illustrations Nos. 53, 54, and 55 is considerable, but the panels are not so beautiful because the bay, the pink, or the lily are so well rendered, but because the pattern of waving lines is so well fitted to the space it has to fill, and the shapes of the silhouettes are so expressive. In the later French marquetry we often find an equal or almost equal dexterity in expressing the natural form, and an almost greater cleverness in adapting the design to the material; but the Italian work has a fineness of style shown in a grace of arrangement and of proportioning the ornament to the space to be filled which is unsurpassable.

Certain remarks made by Mr. Stephen Webb, in a paper read to the Society of Arts on April 28, 1899, as to the qualities which the designer or craftsman must possess for successfully producing intarsia, are worth reproducing here as the sayings of a man who himself has done much beautiful work of the kind. "Tone harmony, and in a limited degree, the sense of values, he must certainly cultivate. He must be able to draw a line or combination of lines which may be ingenious if you like, but must be delicate and graceful, vigorous withal, and in proper relation to any masses which he may introduce into his design. He must thoroughly understand the value of contrast in line and surface form, but these matters, though a stumbling block to the amateur, are the opportunities of the competent designer and craftsman. The most charming possibilities of broken colour lie ready to his hand, to be merely selected by him and introduced into his design. If the wood be properly selected shading is rarely necessary, and if it is done at all should be done by an artist. In the hands of an artist very beautiful effects may be obtained, the same kind of wood being made to yield quite a number of varying shades of colour of a low but rich tone. Over-staining and the abuse of shading are destructive. Ivory has always been a favourite material with workers in tarsia, and in the hands of an experienced designer very charming things may be done with it. There is, however, no material suitable for tarsia which requires so much care and experience in its use. It is ineffective in light-coloured woods, and in the darker ordinary woods, such as ebony, stained mahogany, or rosewood, under polish, the contrast of colour is so great that the ivory must be used very sparingly. The ivory is sometimes stained in order to bring its colour more into harmony with a dark wood-ground, but it is never quite satisfactory. The use of inlay makes the direction from which the light enters the room a matter of no moment, so long as the light reaches the object decorated."

The effect of intarsia has been sought by various imitative processes, some of which are indistinguishable from it except by close inspection. In one of these wax, either in its natural state or tinted with an addition of powder colour, was used; in another glue mixed with whiting or plaster, also sometimes tinged, or red lead. On April 7, 1902, a paper was read at the Royal Institute of British Architects on wax stoppings of this kind by Mr. Heywood Sumner, in the course of which he said that the process he himself had used was as follows:—"First trace the design on the panel of wood to be incised; cut it, either with a V tool or knife blade fixed in a tool-handle; clear out the larger spaces with a small gouge, leaving tool-mark roughness in the bottoms for key; when cut, stop the suction of the wood by several coats of white, hard polish. For coloured stoppings, resin (as white as can be got), beeswax, and powdered distemper are the three things needful. The melted wax may be run into the incisions by means of a small funnel with handle and gas jet affixed; it is attachable to the nearest gas burner by india-rubber tubing, so that a regulated heat can be applied to the funnel. When thus attached and heated, pieces of wax of the required inlay colour are dropped into the funnel, and soon there will be a run of melted wax dropping from the end of the funnel-spout, which is easily guided by means of the wooden handle, and thus the entire panel may be inlaid with the melted wax. Superfluous surface wax is cleared off with a broad chisel, so as to make the whole surface flush. The suction of the wood is stopped by means of white, hard polish, otherwise the hot wax will enter the grain of the wood and stain it. Incised panels may be filled successfully with japanner's gold size and powdered distemper colour, using a palette knife to distribute the slab mixture. A close grain is the one thing needful in the wood. As to design, that which is best suited may be compared to a broad sort of engraving." Red lead was also used sometimes, and in the furniture room at South Kensington there are several chests and other pieces of furniture which have the incised design filled in with a mixture of whiting, glue, and linseed oil.
