What was encaustic
"The word Punic always aroused great hopes that could not be fulfilled". Max Doerner. Los materiales de pintura y su empleo en el arte. 1965, 134.
"There is a common understanding that any method that includes a final burn must be classified as encaustic. Researchers from the eighteenth and nineteenth centuries aimed to look for cold wax methods, not because they ignored the molten wax technique, but because they had the impression, based on legends about the legendary Greek masters and technical writings rather confusing, that the ancients had a second method to paint with wax, and that this secret was lost and had been used in the works of greater merit and delicacy". Ralph Mayer. Materiales y técnicas del arte. 1985, 291.
