A Ph.D was in my shop talking to me about copper. Insisted Turtle Island injuns made everything with just cold hammering.
I said they had to anneal it. Metal doesn't work that way. You cannot keep forging without annealing.
"No, it was only cold hammering."
Faced with someone who does metalwork for a living, Ph.D man plowed ahead with a theory needing magic hammers because he missed the part where annealing is repeated between cold forging.
