#OreCup R2M1: Are you supporting tendrils of native #Copper or dark grains of #ilmenite? Both have less intensive mining processes than most ores & both have fascinating folklore. vote: www.mineralcup.org/vote-results... results:

copper is that girl: ancient tools, essential trace mineral, first synthetic blue pigment (egyptian blue), antibacterial and antimicrobial… she’s given us so much!

It's a tough call but I'm going for the adze of the Copper Chief, who invented step cutting up a glacier hundreds to thousands of years before the Victorian mountaineers did

Still reading about Danish lur horns.

I’m voting for native #Copper, and its continuous importance to pre-historic and modern civilizations. Copper inspires art, music, architecture, tools, weaponry, medicine, energy distribution, and technology. #OreCup25 ⚒️ 🧪

I went to see SUE the T. rex recently, and look who else I ran into! #copper

In Arizona, you are never more than three feet away from Copper*, kind of like spiders. Vote Copper. (*If your reading this, it's true for you, too.)

Sou team Ea Nasir, voto no cobre!

Fun fact- I have a chunk of pure copper from Keeweenaw Peninsula that I use as a door stop. My dad got it out of Lake Superior, decades ago.

Results chart was displaying the wrong rows but it’s fixed now, just waiting for the display to propagate. Your ilmenite votes were recorded, we promise!

Only a few hours left to vote in #OreCup R1M4 #Carrollite vs #Bornite! vote: www.mineralcup.org/vote-results... results:

Titanium ore #Ilmenite soared to victory with a 35% margin. It’ll face off against #Copper in the #OreCup semifinals (tomorrow!!) Nice hustle, #Jadarite, and maybe you’ll have better luck if we find more deposits.

Let's go, #carrollite! The metallic crystals look like scifi design elements. www.mindat.org/photo-336848.... #OreCup

Learning about the difference between #Bornite and #Chalcopyrite this evening. It appears most, if not all, peacock stone on the market is Chalcopyrite. ☹️ Good to know. I was thinking a collection of mineral cup and ore cup winners — if affordable and not deadly — would be cool … #OreCup

Perfect crystal of rare #Carrolite (CuCo2S4) on matrix from Camoya Mine, Congo. #OreCup #sulfides #sulfide #mineral #mineralogy #mineralexpert

It’s a close match, currently 20-ish votes / 6% between contenders. Recruiting be voters will be key to get your voice through to the #OreCup semifinals.

#OreCup closes out round 1 with cobalt ore #Carrollite vs copper-laden #Bornite. Which will you pick? vote: www.mineralcup.org/vote-results... results:

That's the easiest choice yet. Great old names, and a real beauty on top of it. Peacock Ore. Buntkupfer. Kupferlazur. #Bornit

Is holding a grudge against copper fine on such a small cup? After all, it kicked out galena. For that reason alone I feel like abstaining in this round 😡

#Carrollite from Congo at the Tucson show #OreCup #MineralMonday

Lovely peacock ore bornite gets arts points as a source of copper, but so is rare carrollite, which is also a source of cobalt… and cobalt is important for pigments including cobalt violet, cobalt yellow, cobalt titanite green, and of course, cobalt blue. #OreCup

#OreCup R1M4: Will you be entranced by #Carrollite’s octahedral crystals and cobalt ore? Or will the rainbows of peacock rock and its heftier copper content lure you to #Bornite? vote: www.mineralcup.org/vote-results... results:

Nice article on the type locality of #carrollite : Carroll County, Maryland and the Patapsco Mine. https://jamesrada.com/carrollite-the-mineral-once-found-only-in-carroll-county/ #orecup #orecup25 #mincup25 #maryland #sykesville #cobalt

I’m voting for the only Co ore in the Ore Cup, the superconductor mineral #Carrollite. Co serves many industrial, medical, and artistic applications, from battery and magnet technology, to radiotherapy, to glass and ceramic glaze coloring agent. #OreCup25 ⚒️ 🧪

voting carrollite for the cobalt content, but this will be a tough one to win facing off against bornite!

#OreCup R1M4: Take your pick of copper + cobalt #Carrollite vs copper + rainbows #Bornite! vote: www.mineralcup.org/vote-results... results:

was planning on voting for bornite until reading that natural specimens of carrollite exhibit superconductivity 😎

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.) #OreCup

Nice to see #OreCup maintains the primary feature of #MineralCup, making me make TOUGH choices! I’m #TeamCopper so I win either way, but #Bornite is just so pretty, a true rainbow 🌈 rock, and it was named after Ignaz von Born, which makes me think of Ignatz Mouse! Of such things are votes made/cast.

The pretty iridescent peacock colors convinced me to vote for #bornite in today's #OreCup match.

Phew, this is going fast! Ilmenite won & will face cooper in the semifinals tomorrow. Today is the last match in round 1 (quarterfinals! 😂) to pick which ore mineral is up against molybdenite. Hint: they’re both pretty!

Two more copper ores today, but at least #carrollite is also a cobalt ore.

They're both on the "do not lick" list (I assume because the heavy metals involved shouldn't be inhaled) I picked #bornite because it's 🌈

#TeamCopper is going to make it through this match no matter what, so I'm free to vote for the prettier #Bornite. #OreCup

Octahedral crystals, polysynthetic twinning striations, super conductivity, and iridescent sheen? Yes, please. #carrollite #MinCup25 ⚒️ sci-fi 🧪 🖖🏼 scifi Geosciences #WomenInSTEM geology 🔭🪐

We're Team #Ilmenite today in the #OreCup! Not only did it enable Bob Ross's happy little clouds, it also may have helped flip the Moon's mantle. So versatile! 🔭🧪🌕 eos.org/articles/the...

Most abundant oxide on the Moon (www.lpi.usra.edu/publications...). Just sayin. #Ilmenite

Oh my gosh. These are both super cool. Ilmenite is amazing, and I love titanium...but I think I'm gonna vote for the super unusual #Jadarite, which is a lithium borate.

Congratulations, #Molybdenite, your victory is shining a light to #OreCup R2M1. Condolences, #Tetrahedrite, you were sharp but just not enough to make the cut.

Only a few hours left to vote for black titanium ore #Ilmenite or white lithium and boron ore #Jadarite! vote: www.mineralcup.org/vote-results... results: www.mineralcup.org/vote-results... #OreCup

Want to know more about jadarite? Read our #AllMineralsConsidered piece: rdcu.be/eOojc

jadarite needs some votes! it has all the elements mentioned in the formula of kryptonite, but couldn't be called that as krypton itself is an unreactive gas!

Ilmenite a titanium-iron oxide mineral wins the arts vote for titanium dioxide white paint in modern art (like this Klein) Though Jadarite, only discovered in 2004 gets some physics points as a source of lithium (& use in batteries) & some arts points for boron (used in ceramic & glasses) #OreCup
