Copper slag?

**agbkyle** · Nov 02, 2008, 06:47 PM

Hi, I'm new to this forum. I'm from Southeast Mass. Found this next to a river in the woods.
Rang up as copper and is green so I'm assuming it is copper.
Just wondering how to tell if it's an artifact or the result of a melted copper blob.
Search on the internet for "copper slag" shows a couple like it and they're in museums.
Thanks for any info

It does look like slag, I don't know why they would have slag in museums though unless it was a mining museum? The natives didn't smelt/refine their copper by heating it to the melting point so this slag you found must be from historic times.
