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.

Programming notes:
1. The #OreCup final match runs 48 hours, so you still have about 5 hours to campaign!
2. The victory post writeup will take a few days as I forgot I have no childcare on Remembrance Day. Whoops!

#Copper has been holding on to an 8% lead most of the match. It’s a lot, but #Molybdenite could catch up.
What topics should we cover in the #OreCup victory post?

#OreCup finals are between a pair of bewitching ore minerals that glitter and gleam. But only one can have your vote.
Will it be native copper or molybdenite? You’re running out of time to choose!

Lustrous wavy copper stripes this museum specimen of a copper pseudomorph where copper has replaced the original sedimentary bedding.

1/3 Well this is a first (for me): Native #copper replaces ancient cross-bedded sedimentary rock perfectly preserving the original cross-bedding. Copper does amazing stuff in Michigan. 🤯 More below! Pinging @richardgibson.bsky.social

We’re in the final stretch of #OreCup!
Native #Copper is an ore so integral to our history that we named several eras after it and its alloys
#Molybdenite spent centuries tricking us into thinking it was something else entirely

This is #copper. The exquisite golden tetrahexahedral crystal glows with its own light. And the amazing bevels (look closely) and faces! Only nature could create something so beautiful. Vote for Copper Ore. It has it all. Link in ALT.
