109. CRYSTAL VARNISH

Procure a bottle of Canada balsam, which can be had at any druggist's; draw out he cork and set the bottle of balsam at a little distance from the fire, turning it round several times, until the heat has thinned it; then have something that will hold as much as double the quantity of balsam; carry the balsam from the fire, and, while fluid mix it with the same quantity of good turpentine, and shake them together until they are well incorporated. In a few days the varnish is fit for use, particularly if it is poured into a half gallon glass or stone bottle, and kept in a gentle warmth. This varnish is used for maps, prints, charts, drawings, paper, ornaments, &c.
