I annealed some newer pennies so I could dome them tonight. I assumed
that if I want to dome any metal it would have to be annealed first,
One group of pennies I got the flame too hot ad melted a couple. When
I put the others in the pickle, there was sudden and noticable fumes
and I started to cough. I quickly dumped the small container of
pickle and rinsed the pennies in water. They look interesting as the
copper was taken off on one side. My question is why did this happen?
And is there a pickle to use with pennies? Should I have to anneal
them at all to dome?
