100. The graining of chestnut presents no difficulty either to one who has a good knowledge of the handling of graining tools. Its general character is much the same as that of oak and ash. It differs from either, however, and has a growth entirely its own. Its principal points are: Coarseness of veining; its fibres being thick and when cut across by the saw present numerous coarse pores which must be represented by stippling coarsely and somewhat irregularly flogged on, as it shows only a few in parts where the saw has not cut the fibres across either squarely or slanting. 101. The graining of chestnut may be done in either oil by wiping or in distemper. By either method it will be best to stipple it in the manner stated in the previous paragraph—rather coarsely. The ground is a light buff, just about such as described for oak or ash, and may vary to suit the graining MAPLE. 102. The graining of maple differs materially from that of the woods described heretofore. In color it is on the same order, however, of a light buff tone. It should be given a ground color just off the white by the addition of a trifle of ochre to 103. Again as fashion has decreed that maple should be stained a light gray one has to grain it in imitation of that and the ground must then be made by the addition of lamp black to the white base sufficiently to make a faint pearl gray. The veining proper is not very prominent in maple. This consists of very fine lines with little if any feathering. Maple is a very close wood and shows but little if any porousness, therefore should never be stippled. The chief beauty of ordinary maple lays in its mottlings and not in its veinings. Plain maple being what is now under consideration, curled and bird’s eye maple will be taken up in a separate lesson. 104. Plain maple is never grained in oil as it would be too tedious to imitate it by wiping. Therefore its graining by distemper work is the only method worth the while to describe. To be able to grain it well the student must have its character well made out—in his head at least. The color if the wood is grained in its natural color is made from raw sienna weakened down to suit by the addition of whiting. The character of the wood is best produced by the application of the color with a sponge. This should be blended at once and if the color has been properly applied with the sponge, the mottlings produced by the blending of the color will usually suffice and a few more of a deeper tone may be added in the overgraining. As soon as dry, which requires but a few minutes, the veining proper may be put in with the same color with a camel’s hair pencil, but should not be blended. This should be done with a fine pointed brush as it should not be prominent 105. The overgraining of plain maple is done in oil and consists of a few darker mottles made with a brush specially made for this purpose, but which in reality is little better than a plain double thick varnish flat brush, and the latter will be found good enough for this purpose. If the color happens to be too thickly put on, it can be wiped out with a clean rag and left only where it is desired. It should be made of raw sienna darkened with raw and burnt umber and thinned with raw linseed oil and turpentine, half and half. It has been supposed all along that the maple graining was done in its natural color. If gray maple is to be imitated the distemper color should be made from ivory black toned down with whiting and the overgraining color from QUESTIONS ON LESSON XIX.100.
