Encaustic painting is a process of using melted beeswax mixed with damar resin (for hardening) and pigments to create a medium that can be used in many ways. It is a medium, which has lasted over 2000 years on funerary portraits done by the Greeks and Egyptians.
This exciting medium has enjoyed resurgence, first in the fifties and now in the past ten or so years. Artists are pushing the limits of this classic technique to produce paintings, works on paper, sculpture and mixed media pieces.
The only restriction is that the ground for the wax must be porous. Unsealed plywood, bisque fired clay, 300# watercolor paper… all of these are good bases to work with.
The wax and damar medium is kept liquid at a temperature of between 175º to 200º. The wax is bonded to the surface using a propane or butane torch or a hot air gun.
