Material:  N.Carolina Green Slate         Price: $25          Location: Piedmont, NC       Size: 8L x 5W x 3.8 thick

 

Description:  The etching is of a twinned calcite crystal.  The picture is made by scratching the surface of the slate to different depths and/or closeness to get lighter colors.  I did this piece in 1989 and had it packed away until now.  The material is called green slate, but it is really a low silica argillite.  For more information about the material see the links page for the link to the quarry in North Carolina.
