The term "encaustic" comes from the Greek word "enkaustikos," meaning "burning in.” Encaustic painting dates back to a 4th Century BC terracotta krater vase of a painter applying encaustic to a sculpture of Heracles while a servant heats up metal spatulas on a charcoal brazier. Encaustic painting uses hot beeswax mixed with demar resin and pigment to generate layered works of art with depth and texture. Encaustics, like all artwork, should not be exposed to direct sunlight. Colors may fade and wax will melt at 150 degrees. To care for your encaustic art, buff softly in a circular motion with an all-cotton cloth. Do not use a paper towel as it will cause scratches.
