Fine Grain Pyrite is what is needed to make fire by "hitting 2 rocks together". Although rare, this fine-grained Pyrite is suitable for practicing this difficult fire-making technique.

Have you heard about starting a fire by hitting 2 rocks together?

The rocks that are needed to create fire this way are from the Pyrite family, commonly known as "fool's gold".  It is essential that the Pyrite be fine grained and not the large crystalline type that is commonly found in rock shops or Natural History Museums.  Striking these fine grained Pyrites with Flint or against each other (2 Pyrite rocks) will produce sparks, though they are cooler than sparks produced by a flint and steel. 

Pyrrhotite, on the other hand is a close relative to the pyritres and is often associated with
pyrite, chalcopyrite (copper ore) and pentlandite (nickel ore). It is
found in surface veins all over the world and therefore a more practical rock to obtain to make fires with.

We have secured a limited quantity of the fine grained pyrite from ore mines in Canada which are suitable for experimenting with this technique.
