Just a question: what is the blue on the right piece? If you know try to write it in German on Commons and somebody will translate it. Nergaal (talk) 18:25, 3 October 2010 (UTC)[reply]
I think the small blue area is also a thin oxide film layer, similar to the bismuth crystal: —Preceding unsigned comment added by Alchemist-hp (talkcontribs) 18:35, 3 October 2010 (UTC)[reply]
Zinc compounds are colorless though. Nergaal (talk) 16:46, 4 October 2010 (UTC)[reply]
