The fool's gold [Chemistry]
posted February 8 2013 18:29.41 by Giorgos Lazaridis




If you want to dig for gold, beware not to get fooled by the fool's gold. Under certain conditions that can be generated deep inside Earth, iron sulfide can be crystallized and become shiny and yellowish. It is very hard to distinguish this type of iron sulfide from gold ore, thus it got the name "fool's gold"
