Today I was annealing some silver prior to rolling it out in order
to obtain a thinner gauge.
The first annealing, and rolling went well. However on the second
annealing to my dismay the piece of silver, which was about 3" by 5"

from the first rolling, and I had gently pressed on it with my tongs
to flatten it. I have done this before, but never had this happen.
The only thing I can think of that I did differently is that I had
quenched the piece after the first annealing while it was still hot.
Usually I let it air cool. Could this have weakened the molecular
