encaustic painting

A 6th-century encaustic icon from Saint Catherine's Monastery, Egypt, depicting Peter the Apostle Encaustic painting, also known as hot wax painting, is a form of painting that involves a heated wax medium to which colored pigments have been added. The molten mix is applied to a surface—usually prepared wood, though canvas and other materials are sometimes used. The simplest encaustic medium could be made by adding pigments to wax, though recipes most commonly consist of beeswax and damar resin, potentially with other ingredients. For pigmentation, dried powdered pigments can be used, though some artists use pigmented wax, inks, oil paints or other forms of pigmentation.

Metal tools and special brushes can be used to shape the medium as it cools. Also, heated metal tools, including spatulas, knives and scrapers, can be used to manipulate the medium after it has cooled onto the surface. Additionally, heat lamps, torches, heat guns, and other methods of applying heat are used by encaustic artists to fuse and bind the medium. Because encaustic medium is thermally malleable, the medium can be also sculpted, and materials can be encased, collaged or layered into the medium.
