Free copper can still be found in old crt tv's, here I picked up one off the side of the road, took it home to scrap out all the copper components and melt it down into a copper bar.

I recommend this Furnace.. http://amzn.to/2wr7G2k (Affiliate)
It uses Propane Gas which is much cheaper to run with no problems like burning out the element and gives you better options for crucibles like stainless steal or cast iron which last a long time.

If your just in it for the scrap copper then melting it down is not needed, but I like copper bars so as a hobby thing this is what i'm doing.
