History of Encaustic. Encaustic painting is an ancient technique, dating back to the Greeks, who used wax to caulk ship hulls. Pigmenting the wax gave rise to the decorating of warships. The use of encaustic on panels rivaled the use of tempera in what are the earliest known portable easel paintings. Tempera was a faster, cheaper process. Encaustic was a slow, difficult technique, but the paint could be built up in relief, and the wax gave a rich optical effect to the pigment. These characteristics made the finished work startlingly life-like.
