Oh what fun! My daughter found a steam generator at a grade school. It was broken and she took pieces from it. At first I thought they were all steel. But a bath of muratic acid (to get rid of grease and red/black ink) revealed a copper mix. Then a bath of soapy water, then gentle sanding. A lot of work for a necklace but the pieces are so unusual.
