er resins displaced it as equally good, less expensive varnishing materials. Nevertheless the sandarac varnish is still valued today for use as a protective coating on paintings and antiques. It gives a coat which is hard, lustrous and durable. The varnish is made by melting the resin and mixing it with (e.g.) linseed oil (or, in our case, Lavender oil). Sandarac resin melts at about 150°C. to a colorless or slightly yellow liquid.
