Fun with matrix colors - turquoise and chrysocolla
« on: March 21, 2019, 06:37:48 PM »

So I am working on shaping some pieces, when I started on two that really took me aback.  One was a piece of turquoise that was covered in almost solid pyrite matrix.  The other was a piece of chrysocolla from my dad's hometown of Ray, AZ.  When I started grinding away at the turquoise, I was immediately covered in black ink (which I should have expected if I thought about iron pyrite at all).  But what amused me even more was the bright orange residue from the tan matrix of the chrysocolla.  Thought I would share the amusement....and wonder what would make it orange?  Any clues?
