PMC3 Charms look terrible now....:(

[littlecherryhill]

Hi all.

New here and new to PMC, which is why I need help.

I have made 3 pmc3 charms for myself. I waited over night till they were completely dry. Then I torch fired them for approx 2mins each (once they'd reached the 'glow'), then allowed to air dry. Then I polished them up using some super fine steel wool. Then I wore them. I hung them on a chain all freely moving next to each other and they looked great. But yesterday morning when I went to wear them, I noticed they were looking terrible. Scratched all up as though I had been wearing them forever. Then I noticed some black appearing on the back of one of them too

I have pretty much assumed that you can wear pmc3 charms just like you would with sterling. Am I wrong?? Are they too fragile to wear clinking and clanking around each other? Should I be wearing them separately? And what could be the reason for the black??

I have attached pictures of the charms from when they were first finished to how they looked a few days later.

Thanks to anyone who can help me out!!
