Encaustic is the art of painting with molten wax. This style of painting has been around for centuries and was first used to create portraits. In the 20th Century, encaustic painting regained popularity because of its vibrant colors, transparent qualities and durability. Today, encaustic artists use the medium to achieve an incredible range of mixed media effects. Encaustic is generally applied with a brush. It can be scored, molded with tools as it cools, dripped on, or fused with a blowtorch. Artists can also hide objects within the medium by using different melting and layering techniques. It is especially common to embed photos, drawings and writing between layers of encaustic.
