I just inherited a large quantity of old jewelry. There are quite a
number of gold chains in the collection. I’m wondering how to
determine if they are solid gold (they very well could be) or gold
fill, and what the karat of the gold is?
Also, I’m wondering how difficult it is to cast a gold alloy? I have
been doing cuttlefish bone casting with silver with fairly good
success. Is doing the same with gold much different?
I could send the lot to Rio for refining, of course, but I’d rather
play with the stuff myself if I can.
