Gold- Coloured Copal Varnish.

Take 1 ounce powdered copal, 2 ounces essential oil of lavender, and 6 ounces essence of turpentine. Put the oil of lavender into a matrass of a proper size, placed on a sand-bath subject to a moderate heat. When the oil is very warm, add the copal from time to time, in very small quantities, and stir the mixture with a stick of white wood rounded at the end. When the copal has entirely disappeared, put in the turpentine in almost a boiling state, at three different times, and keep continually stirring the mixture till the solution is quite complete.
