[edit] Copper or iron?
Though a product of errant copper metabolism, I recall reading somewhere that the pigment itself is mainly iron, not copper? I changed the article, but upon further inspection could find no evidence to support this, other than the obvious fact that oxidised copper is green, not orange-brown. Anybody got any information?
