Encaustic is a painting method where color-pigmented beeswax is melted, applied to a surface and reheated to fuse the paint into a smooth or textured finish. The word encaustic comes from Greek and means 'to burn in', which refers to the process of fusing the paint. Encaustic has a long history, but it has been experiencing a recent resurgence in popularity due to the increased convenience and safety of heating appliances. The surface can be polished to a high gloss, it can be modeled, sculpted, textured, and combined with collage materials. It cools immediately, so that there is no drying time, yet it can always be reworked. The durability of encaustic is due to the fact that beeswax is impervious to moisture. Because of this it will not deteriorate. Encaustic paintings do not have to be varnished or protected by glass.( IEA Website)
