ANT201H5 Lecture Notes - Lecture 10: Native Copper, Great Orme, Bronze Age
Document Summary
Controlled use of heat: firing of ceramics. 3 major metals: copper, bronze, iron. Also involves the preparation of the ore, like smushing it to remove impurities: primary production smelting (extraction of metal from ore through the application of heat) Most important state since it involves the transformation of the material into metal itself: secondary production. Melt reheat metal to remove impurities or add other metals through a process of alloying - adding multiple metals together to make a new metal like bronze (made of copper and tin) Smiting unique to iron production (further removal of impurities through heating) Casting reheat into liquid to shape in a mold. Fabrication reshape into no liquid shape to mold. Copper ore: extraction required through smelting, transformative craft, occurs naturally below earth"s surface, need specialized skill and knowledge to dig tunnels to deal with gases, poor visibility, and tunnel collapse.
