The heat required to make ceramics is enough to make many smelted metals especially with the fluxes we have proof were known in ancient times. Spalling as a mining technique in Lake Superior lead to the discovery of the use of zinc as a flux and I have artifacts to prove this. Unfortunately I will have to personally fund the study of these or they will never get the research they deserve. I know a lot of people find it hard to imagine our governments are engaged in destroying artifacts like the Kennewick Man site and things that I and many others have. I have not seen any academic suggest that some people learned smelting while making ceramics some 26,000 years ago.
