Product Description Of Roxy Copal Varnish

Roxy Copal Varnish is form to natural gum Rosen dissolved in turpentine or in a mixture of turpentine and a drying oil such aslinseed oil. There are several resins available with which to make a varnish, and the selection of a resin is guided by use. Copal varnish makes an excellent isolating varnish, when used in moderation, and a very hard-surface final varnish. However, Roxy Copal Varnish is more often produced as a convenient source of liquid copal for use in media than as a final protective varnish.Since it has been found that copal varnish darkens and often cracks with age, even without the driers that are commonly added, most recipes call for the use of stand oil or sun-thickened oil to reduce the risk of cracking.
