R&F Encaustic paint is composed of 100-percent pure pharmaceutical grade beeswax, Singapore-grade damar resin and pigments. Beeswax is impervious to moisture making encaustic paint extremely durable. There is no need to varnish or protect your painting with glass. It will not deteriorate, yellow or darken. Encaustic paint is kept molten on a heated palette. It is then applied to an absorbent surface and is fused to create a variety of effects. Encaustic goes from a liquid to solid state and back again in seconds giving you the opportunity to add layers without disrupting your composition. Once the surface has cooled, the paint has reached a permanent finish, but with heat, you can revise and rework your painting minutes or years later. This highly versatile medium can be polished to a high gloss, carved, scraped, layered, collaged, dipped, cast, modeled, sculpted, textured and combine with oil. This set is truly the ultimate palette builder. Each of these carefully chosen colors is beautiful on their own, but this kit has mixing in mind. With these 6 colors you will create a palette of limitless possibilities. The Encaustic Paints Opaque Color Set contains 40-ml encaustic cakes. It includes one each of Titanium White, Cadmium Yellow Medium, Cadmium Red Medium, Cobalt Blue, Chromium Green Oxide and Ivory Black. Also included is a free 6-Inch by 6-Inch cradled Encausticbord by Ampersand.
