Dammar varnish, made from dammar gum dissolved in turpentine, was introduced as a picture varnish in 1826; commonly used in oil painting, both during the painting process and after the painting is finished. Dammar varnish and similar gum varnishes auto-oxidize and yellow over a relatively short time regardless of storage method; this effect is more pronounced on artwork stored in darkness than with works on display in light due to the bleaching effects of sunlight on the colorants involved.
Batik is made from dammar crystals dissolved in molten paraffin wax, to prevent the wax from cracking when it is drawn onto silk or rayon.
Encaustic Paints are made from dammar crystals in beeswax with pigment added. The dammar crystals serve as a hardening agent.
As caulk for ships in the past, frequently with pitch or bitumen.
