The word encaustic originates from the Greek word enkaustikos which means to burn in, and this element of heat is necessary for a painting to be called encaustic. This technique was notably used in Egypt around 100–300 AD. Encaustic painting, also known as hot wax painting, involves using heated beeswax to which colored pigments are added. The liquid or paste is then applied to a surface, usually prepared wood, although canvas and other materials can also be used.
Metal tools and metal brushes can be used to shape the paint before it cools, or heated metal tools can be used to manipulate the wax once it has cooled onto the surface. Today, tools such as heat lamps, heat guns, and other methods of applying heat allow artists to extend the amount of time they have to work with the material. Wax is used as the pigment binder, encaustics can be sculpted and painted. Photos and materials can be collage onto the surface, or layered, using the encaustic medium to attach them to the surface.
I am sharing a few examples of my encaustic paintings using the metal tools and hot iron.
