combing, take raw sienna with burnt umber or Vandyke brown, according to the depth of color required. These colors can be procured very finely ground in oil. Mix up the colors with half oil and half turps, and add 1⁄2 ounce of driers to each pound of color as a megilp to enable the color to stand the combing. The overgraining color should be ground in water. Mix it up with equal quantities of beer and water. The work should be so managed that the overgraining will not contrast with the under work, but will darken it. A slight coat of turpentine, with which is mixed a small quantity of japanners' gold size, added after the work is dry, will bind down the overgrain and allow of the work being finally glazed with Vandyke brown mixed with oil.
