Howdy potters,
I have stumbled onto a 50# bag of zinc oxide it must be 15-20 years old. =
It is still in the original bag and has been stored in a plastic bag. =
Problem..... it is rock hard. Can this be saved? Would it need to be =
ball milled (don't have one) or some how pulverized? With zinc going =
for over $2.00 a pound it's gonna kill me to toss it.
