Naturally occurring pure copper is called “native” copper & is formed in veins & fractures by super-heated mineral-rich fluids often associated with volcanic activity. My sample shown below. Get the lead out & vote #copper!

The Flemish masters painted on #copper as it provided a smooth surface that allowed fine detail and durability of their exquisite works, like this self portrait of Rembrandt.

Remember dendrites (from the Greek word dendron meaning tree)? They are tree-like minerals that form under special conditions. There is a lovely dendritic #copper sample on the upper right. Thanks Susie! More in comment 👇🏼

Might vote for #galena for local cultural reasons. It’s Wisconsin’s state mineral, recognizing the history of lead mining here.
And our state mascot, the Badger, is a reference to the miners and their numerous “badger” holes.

🪨A Neolithic scraper made from a breccia of Galena. It shows wear from use; perhaps a status implement. Galena is a sulphide mineral which has anti-microbial properties, which would have been useful in processing hides🐄🐐🐏

#Copper was likely first metal used for tools. And Native Americans, over 9,000 years ago, were likely first coppersmiths.
