Thanks for copying both Dale's and my info over here, Sue. I'm flattered and glad you found our responses helpful.
Oh boy, Desa, I hope you weren't hurt, and hope you had really good ventilation! If I had to guess, your key might have been zinc coated. Dale can help me out here if he's reading, but I believe zinc is a common coating on steel.
Swamper mentioned in Sue's other thread that she was looking into the best ways to remove any coatings and get to the key's base metal. Putting them in a tumbler to remove rust, as folks are discussing here, might be another way to remove coatings, too.
I love the work folks have been posting with their beads on keys, by the way - very unique, beautiful and distinctive!
