For as hard as pyrite is on the Mohs hardness scale, it is actually pretty brittle and can even be pulverized down into a powder. Too much heat can crack your pyrite or cause it to become flakey. Also take note that pyrite is mostly made of iron, which is a metal. Metals absorb heat and can cause burns if they get too hot and touch the skin. Related Questions Articles.

Mohs' scale of mineral hardness characterizes the scratch resistance of various minerals through the ability of a harder material to scratch a softer material. For instance, if you scratched a diamond along a pane of glass, the glass would scratch and it wouldn't harm the diamond in any way. It was created, in 1812, by the German mineralogist Friedrich Mohs and is one of several definitions of ...

Pyrite (hardness 66 1/2) Pyrite (iron sulfide, FeS 2) is a pale, brassyellow, opaque mineral that is brittle and has a metallic luster. It makes a black streak and is so hard that it can scratch glass. Most pyrite crystals are cubeshaped (like galena), but they also occur in other forms such as octahedrons. Pyrite is also found as granular masses, as cones and globules, and as nodules in ...
