Making copper the ancient way

This summer we made several experiments reducing malachite (copper carbonate) to genuine copper with blowpipes in open fire pits. Now we know that it is possible to make metallic copper only using lung power and Copper Age equipment. This video was meant as documentation of an archaeological experiment. Thanks to all visitors who added relevant comments by now! But: As more and more stupids felt called to misuse the comment function as a trash dump of their verbal diarrhea, today I decided to switch it of, sorry, folks! My life´s too short for this.
