Copper Casting In America (Trevelyan)
monster snip
Considering copper :
1. find some rich ore or native or near native.
2. build one hot fire - continue burning and increase coal / charcoal contents.
3. add copper or ore - perhaps using glass technology of the time - pit glass ?
more melted stone that is glassy and use this slab as a cookie sheet . :-)
