Michigan copper


Well-Known Member
Went out to do a little detecing this afternoon but it started pouring so I came home deceided to clean some copper. I had a chunk of copper and quartz that I had been wanting to clean for awhile now and today was the day. I used Sulfamic acid it'll take a little while for it to eat the quartz and other rock. Tried selling it to a gem and gift shop here in town but he didn't want it because of all the qrtz and rock.
All the mud looking colors ar copper it weighs about 20 30 lbs.w/rock and qrtz I'll see what it weighs after. There are some little chunks as well in the solution. Will post pics when it's all cleaned up if any one is interested?
Thanks for looking.
