But in graining oak in distemper, the graining colour consists of other materials; many receipts are given, but one is Vandyke brown, burnt umber, and raw umber, mixed into a paint with beer or ale. This is laid on with a brush, and the subsequent processes of producing the grain, the light patches, the dark veins, &c., are much the same as in oil graining, with this exception, that the grain is produced by _veining brushes_, instead of _graining combs_. When the whole is dry, it receives one or two coats of varnish, to act as a preservative. By processes very similar to that just described, mahogany, rose-wood, satin-wood, maple, pollard oak, zebra-wood, walnut-wood, elm, and other species of wood, are imitated. For mahogany, the ground is Venetian red and white lead, and the graining colour is Sienna, or Vandyke brown, ground in beer. For rose-wood, the ground is lake, vermilion, and flake white, and the graining colour Vandyke brown, ground in ale. For satin-wood, the ground is the same as for light oak, and the graining colour is Oxford ochre, ground in ale. The other kinds of wood are imitated by grounds and graining colours more or less resembling those now mentioned. The manual use of the tools is more difficult for the variegated woods than for oak. Satin-wood, and some other kinds, have large spots or patches of a lighter colour than the rest of the wood, and of a peculiarly soft appearance; these are imitated by letting a sponge fall on various parts of the wet graining colour, by which some is wiped off, and the edges of these parts are then softened by means of a badger-hair brush, called a _soft even_, which is drawn lightly across the light and dark parts, whereby the sharp edges are softened and blended.
