An excellent varnish, in which may be put, and diluted, whatever colour you like.-It suits, equally well, goldsmiths and limners.

Take aspic and turpentine oils, of each one ounce; clean picked sandarak pulverised, four drachms; gum copal, two. The whole being well pulverised, put it along with your oils in a matrass, with the addition of half a pound of spirit of wine; and set it in a balneo maria. When the matter is dissolved, strain and keep it for use, in a glass bottle well stopped.
