I am learning wire wrapping, so by default, I am also learning about wire and some of its properties and what you can and can not do with it. Example: I wrapped this stone cabachon with silver plated wire and decided to polish it after I was done. So, I used a sunshine cloth and went to work, and to my horror, the plating started to rub off! You can see where a little of it has buffed off on the top left corner! So, now I am afraid to polish anything... I see why everyone uses sterling silver for the items they sell!
