We have successfully added a pickle to our jewelry class! A pickle (yes, a pickle) is a warm acidic mixer (in our case) of vinegar, salt and water that makes it easier to clean jewelry. It is a little slower than professional pickles that use a stronger acid, but it is non-toxic and effective. It's called a pickle because years ago, they would use the left over vinegar from making pickles to clean metal. Hopefully student's work will come out beautiful and shiny!!
