Blackening silver with a hard-boiled egg

By Jack and Elizabeth Gualtieri

Editor’s Note: Blackened silver is one of the hottest trends in jewelry today. The process involves coating a piece of silver with one of a number of solutions that blackens the surface. While researching this process, the MJSA editorial team learned about another method for blackening silver that piqued our interest: the hard-boiled-egg method. (We found instructions for this method on the Long Canyon Jewelry website.)

We asked goldsmiths Jack and Elizabeth Gualtieri of Zaffiro in Portland, Oregon, whose Etrusco collection features blackened fine silver accented with 22k granules, to give the egg method a shot. They were game. You’ll find the results of their experiment below.
