shines like a dirty old penny

Although it does what it's supposed to do, it doesn't tell you that the powder you get is almost completely oxidized. It's a deep tan color, like an old dirty penny, and the only way to get it really bright as shown in the photos is to treat it with baking soda or a weak hydrochloric acid solution first. Otherwise it will never hold when you electroplate and won't shine as they show when you mold.
