Gum Mastic

Starting at: £20.30

Call to Order

Gum Mastic is a tree resin, which dissolves into a clear varnish with alcohol or turpentine, but not with mineral spirits. Mastic varnishes are more prone to blooming and darkening with age than damar-based varnishes, and painting mediums that contain gum mastic can deteriorate in unpredictable ways. For this reason, it is primarily used in restoration, rather than in the production of artwork. Learn More

Gum Damar

Starting at: £10.00

Damar is a pale, almost colourless tree resin, which is soluble in turpentine, but not in alcohol or mineral spirits. It can be used as a varnish or as a glossy painting medium in conjunction with vegetable oils, and is generally preferable to other resin-based varnishes, such as mastic varnish, as it retains its colourless appearance for a longer period of time. In encaustic painting, the inclusion of damar resin imparts toughness and gloss to the paint surface. Learn More
