Encaustic
Encaustic painting, also called "hot wax painting", involves using heated beeswax to which colored pigments are added. The liquid/paste is then applied to a surface usually prepared wood, though also canvas and other materials.
Metal tools are used to shape the paint before it cools; also special brushes. This technique was notably used in the Fayum mummy portraits from Egypt around 100-300 CE, as well as in many works of the 20th century American artist, Jasper Johns.
