I mean, look at this: iopscience.iop.org/article/10.1... It's ridiculously more effective alone than anything else. Even combinations of the others studied didn't come close. At the same time we actually need copper, so it isn't as toxic to us as silver.

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.

#OreCup ⚒️ sci-fi 🧪 🖖🏼 scifi Geosciences #WomenInSTEM geology 🍎 🔭🪐 Canada knows copper is the best ore!

#Copper, copper, copper!!! It’s the final, please vote for the very best ore! #OreCup

Delicious:) #OreCup ⚒️ sci-fi 🧪 🖖🏼 scifi Geosciences #WomenInSTEM geology 🍎 🔭🪐

Copper's antimicrobial properties are also much better than silver's, and they carry over to many alloys. Hopefully we'll be seeing a lot more brass handles in the future.

#Copper is an excellent material for crafting art due to its beauty & malleability, & allows for exquisitely detailed work such as copper hammering & tooling. Enjoy the examples below & vote for copper ore! Descriptions in ALT. #OreCup ⚒️ sci-fi 🧪 🖖🏼 scifi Geosciences #WomenInSTEM geology 🍎 🔭🪐

I'm Ea-Nasir and I approve this message.

Of all the minerals in the #OreCup for my art/physics use voting scheme copper wins hands down! Ok, molybdenum has some applications as catalyst/electrodes/in alloys but copper is the conductor par excellence. In art we have all of bronze & copper sculpture & many blue/green pigments! Vote copper!

Final round for the first annual #orecup contest. Don't believe the link in the quoted post, which goes to a semifinal round: the final vote is at www.mineralcup.org/vote-results.... I am not going to say who I voted for, because my endorsements would have been the kiss of death in previous rounds.

#OreCup FINALS: Place your vote to decide the IMA Ore Mineral of the Year! Are you a fan of the classic native metal #Copper, or the slippery silver #Molybdenite that evaded being pinned down for so long? Vote:

Countless places copper shines Old artifacts to power lines Pennies in lemon batteries Pots and pans to heat with ease Ethernet, plumbing, jewelry, art Recycling to a new bright start #OreCup #MinPoem #TeamCopper

We're in the finals! #Copper for the #OreCup win!

#OreCup Finals: It’s copper ore native #Copper vs molybdenum (& rhenium) ore #Molybdenite. Both are shiny, but only one can be the Ore Mineral of the Year Vote:

#OreCup The answer is obvious. Don't be stubborn: #Copper is inevitable.

Oh dear #Bornite is gone… 😞 … along with all the other OREsome OREs …. Let’s hope #Copper will become the OREsomest ORE of them all. #OreCup

Fun competition- vote for copper! Michiganders, I’m looking at you! Here’s a nicely cleaned UP ore for motivation.

Copper helps power the entire planet, enables the transition to greener technology, is crucial for the production of red blood cells, & makes exquisite & durable art. Throw in 100% recyclability, & you have the perfect ore. #NoLube :) #OreCup ⚒️ sci-fi 🧪 🖖🏼 scifi Geosciences #WomenInSTEM geology 🍎 🔭🪐

The Old Copper complex, was an ancient Native American culture around Michigan that mined (>5,000 mines) & worked the 99% pure native copper for tools, weapons, and ornaments as far back as 9,500 yrs.

vote the peacock — one of the most colorful breccia pipes you can stumble across Better than copper so best kept in the ground as you found it. www.oregon.gov/dogami/milo/...

Bornite is great, but #molybdenite is not copper! I kid (kind of)! A soft, silver, greasy, hexagonal mineral that can look like JiffyPop, foil-wrapped leftovers, or metallic graphite. It can handle high-stress/high-temps, & it's anti-corrosive. Those seem like good qualities here & now! #OreCup

Only a few hours left to vote in the #OreCup semifinals of #Molybdenite vs #Bornite! vote: www.mineralcup.org/vote-results... results:

We didn’t always recognize #Molybdenite or know how to use Mo until the late 19th Century. Rh wasn’t discovered until 1908. After early experiments during WWI, automobile and aviation industries found uses for both elements in high-performance alloys. Then catalysts and medical uses. #OreCup25 ⚒️ 🧪

Peacock ore Bornite is very pretty but only gets art/physics points as a source of copper & I’d rather vote for copper itself. So I am going to vote Molybdenite for physics reasons (source of Re for geochronology, Mo used as a catalyst, battery electrodes, alloys of iron & semiconductors). #OreCup

>sigh< I voted for #Bornite, because, it's pretty. There, I said it. #OreCup www.mineralcup.org/vote-results...

#OreCup is in the final stretch! Are you supporting the only molybdenum (and rhenium) ore #Molybdenite, or the hefty copper sulphide with the rainbow sheen #Bornite? vote: www.mineralcup.org/vote-results... results:

It’s time to vote for molybdenite or bornite. Choose wisely. But don’t fret over it too much. Copper will eventually win the final match. 😊 #OreCup

#Bornite still has my vote with those peacock colors. Professional science nerd or not,sometimes my magpie brain takes over. #OreCup

The gremlins really got us today. 🫠 Voting page URL is fixed now, too

Congratulations to #Copper on a winning by a decisive 27% margin. Whatever happens in the Finals, you won’t be going home with bronze. Condolences, #Ilmenite, but we’re confident you’ll weather this setback with your usual resilience.

Well, that’s embarrassing! We forgot to update the poll with our last semifinalist. 😂 It’s fixed now. Don’t worry, tk2-voters. Your votes were recorded and are now assigned to Bornite. Apologies for the confusion!

It feels like gloating, but #copper is romping home with this one! Sorry #ilmenite

Copper has my heart.

#OreCup #Copper

Always a big ⚒️🧪 fan of #copper. We use it for vacuum gaskets which we then give away to visiting school groups - they find it fascinating because although copper is everywhere it's rare to actually *see* it. There's probably a kilo or so of copper in your immediate vicinity.

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

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 ⚒️ 🧪

#OreCup I love #Ilmenite, but, #Copper does this, & so much more. >sigh<

I’ll grant Ilmenite a titanium-iron oxide mineral with idealized formula FeTiO3 some arts points for titanium dioxide white paint but it’s no match for copper’s centuries of blue-green pigments, bronze sculpture & direct use through art history! Vote Copper! #TeamCopper #OreCup #artHist

#OreCup #copper is one of only two coloured metals ⚒️🧪 The iconic reddish color is due to a peculiarity in the transition of electrons between the 3d and 4s orbitals causing absorption of blue and green wavelengths and reflecting red/orange wavelengths. Also makes it a great electrical conductor.

Go read this and then vote for your favourite story! (I voted for the one that would involve repatriation from the Smithsonian!) #OreCup

#OreCup I'm feeling silly, so, I #vote #Copper instead of #Ilmenite, because of these #illustrations in the #pictures in the #comment #field. www.mineralcup.org/vote-results...
