Fwd: [ancient_waterways_society] Heat problem of smelting copper
- In colonial times one of the tax stamp items was pottery, and it had top be made in England. The coastal regions are full of clay banks and wood fired kilns set up like chimneys in hillsides enabled them to reach temperatures of stoneware for jugs, dishes, and such.

Some of the new dates for the habitation sites in the Amazon are around 10000 before present and that challenges a lot of theories that have been accepted fact for a few decades.A hide bag allowed bronze age smelters create primitive bellows for their metal making around the Mediterranean. I think the native americans could also have developed a similar technology.tedPSThere is a group in Minneapolis that is experimenting with primitive charcoal methods of working with copper. Let me know if you want to get information on that group.
