There are many metals in the family called steel.
Huh?
There are many suckers in the religion called MORMONism.
Yes there are, however, you still fail to answer my question - even the basic IRON smelting processes leave waste materials, in addition to steel. And steel still requires a more advanced knowledge of metallurgy than is evident in the Americas during the bom times. Again, FARM/Maxwell tries to claim that the 'steel' of the bom is actually wood clubs with obsidian chips embedded in it - that cannot be covered by ANY 'metal' in the family called steel.
So what precious materials in that list were not used bm?
