    There is a Testing Solution that we use I comes premixed in a
    bottle. You could buy this from Rio, Stuller or 46 Jewelry. The cost
    is around 2 to 3 dollars. This is a test with Potassium Dichromate
    and this turns the test piece into dark red. brown, etc., and this
    helps you determine the purity of the silver. The color chart is on
    the bottle itself. Get a fresh bottle as there is a shelf life on
    this product.
