📖 Über Copper

One of the first metals used by humans, with artifacts dating back 10,000 years. The Bronze Age was defined by copper alloys (bronze = copper + tin). Copper is the third most consumed industrial metal after iron and aluminium. It is an essential trace element in biology and has natural antimicrobial properties.
