Some of the copper that I smelted at the Sculpture workshop was not very pure. By hammering it I was able to get rid of much of the impurities ready to alloy with silver and melt for casting. I think that this was the first time that I used this blacksmiths hammer and my rather rusty anvil/
The second ‘hole in the ground’ smelt produced copper in pellets, it was probably just a smidge too cool, but pellets will be super handy for casting.
We did a third smelt, but I don’t have photos as yet. It produced more consolidated copper at about the same ratio of ore to metal.

This malachite arrived from Denmark this week. Thanks to Anders of the Experimental Historical Bronze Casting Group – see the internet does still have some good things. My intention is to try and smelt copper from it and I’m heading to the Scottish Sculpture Workshop to discuss options. It also occurs near to St Andrews, but I’ve yet to get any from this source. Malachite has been used to give copper for thousands of years.
