Encaustic is a painting medium that uses filtered beeswax and natural tree resin. The resin raises the melting point of the wax and also makes the wax shinier, harder and more durable. Encaustic paintings over 2,000 years old have been found in good condition in Egypt and the ancient Greeks used encaustic to decorate their ships.
The wax and resin mixture (called encaustic medium) is applied molten - usually to a board or panel, though sometimes to linen or paper - and is built up on the surface in layers. These layers are part of what gives encaustic its incredible depth and luminous qualities.
The encaustic medium is mixed with pigments to create paint. The paint is applied molten and can be manipulated both warm and cold to obtain amazing effects.
