Yes, cuprosklodowskite is the copper-bearing version of sklodowskite, the mineral named for Marie Curie (neé Sklodowska), but #Mannardite is the little goth rock who could! Jet black & found in the oldest terrestrial rocks, Hadean era crust! #MinCup25

Voting Mannardite because A) I suspect it's an underdog, and B) I knew a guy once named Maynard and he was cool. 😄 Of such tenuous things can matches be decided. But I don't mind my frippery votes, because with #MinCup, we're all winners! 🏆

Molybdenite all the way! Who can resist what I like to think of as fool's silver? #MinCup25

#Molybdenite Dioptase looks nice, but don't touch! Molybdenite's grease is useful, and will live on in your heart, your shirt, the door, the cat and everything else! Vote Molybdenite today!

Difficult choice today. I like green, but #molybdenite is already a bit behind in the race. So, go for the underdog! #MinCup25

What appears to be a single Borg-like #perovskite crystal is an intergrowth of repetitively “twinned” crystals that have formed striations and very complex faces. How? See comment. Photo from Mindat-link in ALT. Vote perovskite below #MinCup25 ⚒️ sci-fi 🧪 🖖🏼 scifi Geosciences #WomenInSTEM geology 🔭🪐

Perovskite had me at "found in the rain on brown dwarf stars..." That is the most arresting sentence I've read in days.

During lunch, I introduced the rest of the lab to #MinCup25, they were not aware about it. Sorry, @lesuper.bsky.uy ,but I was not able to convince all of them to support my vote for #perovskite.

Perovskite fact of round 2: Perovskite type materials have long been studied for their usage in radiation shielding but today I learned other Perovskites are also being studied for radiation detection! Double win for the cubes! #MinCup25 #Perovskite

In #MinCup25 today it's got to be perovskite for me! My favourite flavour is titanate perovskite because it's found in nature to be jam-packed full of uranium and thorium! ☢️ For that reason it's of interest as a ceramic host for radioactive waste.

From the rain of brown dwarf stars to Earth's mantle and crust, we'll say it again: perovskite or bust!

This hurts, so deep…I've been dreading this #MinCup25 match, just as I dread a match with #kyanite… I took no pleasure in opposing calcite, & I have to once again betray my own field & stick it out with the green energy mineral, potential first rock of our solar system, #perovskite

Easy. #Perovskite all the way. Stibnite is the mineral equivalent of the person who says "this is more a comment than a question." #Perovskite would ask an insightful question that would generate interesting discussion.

Voting for solar panels this time around. #Perovskite

#stibnite is poisonous and used in fireworks that pollute our environment - so #perovskite it is! It just reminds me of the #starwars Borg Cube - what could be cooler? 😎🤩

I fully agree. How beautiful and useful a structure to be one of the most popular mineral name in everyday news reports. Do your research and find it for yourself. Vote #Perovskite

Vote #perovskite in #MinCup25! A lot of negativity toward this fine mineral this morning. It isn’t perovskite’s fault that its structure is so remarkable and *inclusive* that its name has been used to describe, amongst many other things, the most abundant mineral in the Earth (now bridgmanite).

How can you be a solid-state chemist and vote anything but #perovskite ?

Chant it with me: PE-ROV-SKITE! PE-ROV-SKITE! #Perovskite

#Perovskite Borg-like crystals can have complex faces, In fact, perovskite has a wide range of morphologies. Perovskite rains from brown dwarves, and perovskite structure fuels brilliant new technologies. Resistance is Futile. #VoteTheFuture #MinCup25

OMG! Perovskite and calcite are tied! #mincup25 #perovskite

Yay #perovskite!

#perovskite gets my vote -- brown dwarf chemistry all the way!

A vote for #Perovskite is a vote for the future. Perovskites are particularly promising for space exploration, where high power-to-weight ratios and performance in low-light conditions are crucial for satellites and planetary missions. Imagine. See comment below for more. #MinCup25

The more I read about #perovskite the more I love it. A vote for perovskite is a vote for the future. #mincup25

It's a reminder that we are all made of stars (as it's found in the Earth's mantle and in brown dwarf & other stars & some meteorites)! Cast your vote for our solid, interstellar, pseudo-cubic friend #Perovskite! #MinCup25 🌟

Low-temperature stars have spectra characterized by TiO, but as the temperature drops, those bands disappear. This is due to the formation of #perovskite grains that rain down on the star (or brown dwarf). You don't get more spacey than that, so for this round of #MinCup25, it's perovskite for me.

Whoa, this was enough to sell me. It's #perovskite for me this round in #MinCup25!

If you haven’t voted yet, let this adorable little #perovskite crystal remind you there’s still time! #VoteForTheFuture. #VotePerovskite #MinCup25 Scifi &Fantasy ⚒️🧪 Vote here: www.mineralcup.org/2025/vote/r1...
