A friend is retiring his century-old family printing business. He has a fair quantity of a variety of gold embossing powder of various eras and types. He'd like to know what he has and what he should do with it. Kitco says one powder has reasonable content but is difficult to refine. I've read the threads here from about 5 years ago but found nothing within our limited skill level.
Can anyone here with experience in testing and refining embossing powders offer advice about simple tests to reliably eliminate non-gold-bearing powders and test and refine gold-bearing powders? Or are the bearing powders worth more as powders?
Thanks.
