What Is Encaustic?
Encaustic is a Greek word meaning “to heat or burn in” (enkaustikos). Heat is used throughout the process, from melting the beeswax and Damar resin, to fusing the layers of wax. Encaustic consists of natural bees wax and damar resin (crystallized tree sap). The medium can be used alone for its transparency or coloured pigment added. The medium is used molten and applied with a brush or any tool you wish to. Each layer is then reheated to fuse it to the previous layer.
The question I get most asked is "Will it melt"? and the answer is "yes, of course it will, it's wax"! But the melting point of encaustic medium is 155*F, so we have a lot more than artwork melting to worry about if it gets that hot!
So, this really means in the home keep paintings out of direct sunlight, and avoid areas that are above heaters or near incandescent lights.
