The other day I was annealing newly purchased pure silver ingots to
roll them out and saw that when heated, the silver “bubbled”. And
when the metal was rolled out and continued to be worked, the bubbles
didn’t go away. In fact, more appeared as I repeatedly annealed.
Has anyone experienced this with newly purchased fine silver ounce
ingots? Any ways around this? I couldn’t use the silver for rolling
out. I guess it goes into the crucible for casting. Will the
"bubbles" carry over there as porosity?
Looking forward to
