There was mentioned some time back some form of copper powder is sold as  
pigment in arts stores, it is black or brown i think.
Maybe it is that, but i wouldn't expect that is sold in a electronics  
store, while FeCl is highly likely.
There was a document describing how to convert the "pigment" copper into  
CuCl.
