I have an old vial with a small amount of gold in it. I would like to weigh the gold to see just how much is in there. I just bought a small digital scale but now I'm wondering just how to weigh only the gold. I can weight an empty vial, but not the amount of water unless it is still mixed in with the gold. Now, somewhere and long ago, I read an article about just how to do this, but I can't remember where or when or how. Any suggestions as to how? or where I might have read about this process? Was probably about 10-15 years ago.
Thanks in advance for any help at all.
