Ahh a refreshing new vote in the #orecup!
Are you cheering on #Ilmenite, titanium ore of aircraft parts and artificial knees, or #Jadarite, lithium & boron ore of rechargeable batteries and thin smartphone screens?

Oh hell yes! #orecup. Let's go!
A large, split chunk of #galena for the #OreCup found reasonably local in the mining spoil which was closed after “some thousands (were spent) in search of lead ore and never found a pound weight”. I always find this funny as the hill is covered galena and wonder what they were doing.

Copper has my #OreCup art vote not just because of all the lovely colours it makes but also the copper tlakwa made by peoples of the northwest coast of North America, storied objects exchanged and ritualistically damaged/destroyed for political and cermonial reasons. easteast.world/posts/117

I have to endorse #Carrollite today—copper PLUS cobalt!
1st I love cobalt blue
2nd cobalt comes from kobold, the German name for an imp or demon, so named bc it made recovery of silver (from ores where they mixed) more difficult to recover.
(Yes that’s where D&D got it.)

Not just pennies, copper has been a key part of history, a major player in world economics.

I think it's cool how copper connects to tectonics - a failed rift in Michigan, ocean floor stranded by convergent tectonics in Cyprus - and how that tectonics connects to human use of metals.

Copper crystals can form beautiful leafy patterns called dendrites from the Greek word dendron meaning tree. Dendrites grow due to mineral-rich fluids moving through cracks or during rapid cooling from a melt or vapor. Vote and more👇🏼

Patinating copper is a thing apparently. Not for the faint of heart.
It involves ammonia, salt, water and a fumigation container.
