The copper slug on the left hand side was made up from thin copper wire balled and compressed before melting, the slug on the right came from copper waste sludge from my refining stock pot a swipe with nitric acid shows that there are some precious metals present.
The slug on the right will be remelted into an anode for parting in a cell.
My only regret is not buying the induction furnace sooner, no more propane bottle freezing or running out of fuel at a crucial moment.
