Quick Tip For Identifying Fire Scale On Sterling Silver

In this video, Professor John Ahr of the Online Jewelry Academy gives viewers a great tip on how to find fire scale on a silver surface. All you need is a sheet of white paper to reflect onto the silver surface in question.

You can remove fire scale using abrasive processes like sanding and polishing. Or, you can hide it through plating or frosting. Frosting is a depletion plating process where the metal is heated to about 850 degrees, cooled, pickled, and brass brushed as many as twenty times. This raises a fine silver layer that will hide fire scale.
