TO PAINT ORNAMENTAL LEATHER WORK.
Use finely powdered colours, and mix them to the consistence of cream, with the following medium:—Mix the white of an egg with 2 oz. of pure distilled vinegar; put them into a bottle and shake them well together whenever you are about to mix any colours with it: or mix the colours with parchment size warmed; use while warm: or mix them with a weak solution of gum arabic; and, in either case, varnish them with a quick drying pale varnish. Oil colours will not do for painting this kind of materials: any of the above mediums, properly prepared, will answer well. Gilding may be interspersed with brilliant effect.
