Mining Museum: New Almaden

The Mining Museum is located in Casa Grande.  The mining f mercury was very interesting.  Mining the ore was not dangerous.  The mercury is in a solid state and poses no threat.  however in the process of mercury it had to be evaporated, and the gas collected.  this did pose a risk, so the workers could only work one day per month in the processing of the ore.  They gave me a large rock of cinnebar to heft and it was very heavy for its size.
