1694. In grayish or brownish stones, the stain will be wanting in brightness, because the natural color combines with the stain; therefore, if the stone be of a pure color, the result will be a combination of the color and stain.
1695. Bone or Ivory.—In staining bone or ivory, the colors will take better before than after polishing; and if any dark spots appear, they should be rubbed with chalk, and the article dyed again to produce uniformity of shade. On removal from the boiling-hot dye-bath, the bone should be immediately plunged into cold water, to prevent cracks from the heat.
1696. Paper or Parchment is stained; a broad varnish brush should be employed to lay the coloring on evenly.
1697. Wood.—When the stains for wood are required to be very strong, it is better to soak and not brush them; therefore if for inlaying or fine work, the wood should be previously split or sawn into proper thicknesses, and when directed to be brushed several times over with the stains, it should be allowed to dry between each coating.
1698. To Varnish.—When it is wished to render any of the stains more durable and beautiful, the work should be well rubbed with Dutch or common rushes after it is colored, and then varnished with seed-lac varnish, or if a better appearance is desired, with three coats of the same, or shellac varnish.
