Oldies but Goodies - Patina

Patina is not always something that we love. Blackened silver flatware or jewelry, green copper and more that we have to clean don't have many fans if any at all, and of course patina is not only found on metals, either.
Often, however, a nice patina adds to the beauty of a piece, no matter if it developed on purpose or not. Oxidizing and colorful patinas are a part of jewelry making as the selection from this week's Jewelry Artisans Community Oldies but Goodies Challenge is about to show us - and don't forget, there is more to see if you click through!
