60 Centuries of Copper: Early Smelting Practice

The Romans improved on the early primitive methods, but without altering the fundamental principle; and, as already mentioned, they successfully smelted sulfide ores, which would have defied the more ancient metallurgists. In Britain there has been found in Anglesey a number of circular cakes of copper which were cast in Roman times.
