Encaustic painting uses melted beeswax and damar resin (a tree resin) combined with colored pigments that is painted on wood or other rigid porous materials (I like old books too). A heat gun is used to fuse the various layers. You can click on the thumbnails for an enlarged image.

WWI Encaustics

Encaustic Pigments: Like many artists’ paints, some encaustic colors rely on the use of toxic metals like cadmium and chrome. Cadmium is one of the most toxic heavy metals, not just to humans but aquatic life as well. I do not use cadmium or chrome based colors in any of my artwork.
