Through the years I received platinum in various forms. It's difficult to avoid when you refine for jewelers, or if you refine dental gold.
Hoke's book details the processing of platinum, which is rather interesting to observe, and easily accomplished.
For those of you that may have never seen the process, I have attached a photo in which you'll see a small bottle of yellow/orange salt, chloroplatinic acid, platinum precipitated with ammonium chloride. The second bottle represents the platinum salt that has been calcined, and the third bottle contains a tiny platinum button.
In front, to the left, there is a coil of platinum ----which is the first lot of platinum I recovered. It was a small button that weighed roughly 4 grams, and was rolled to a length of about 16". The button to the right is platinum as well, and weighs approximately 1.15 ounces.
