#stibnite — Public Fediverse posts

A spectacular stibnite. With its hundreds of bladelike crystals, this stunning specimen is one of the largest stibnites on public display in the world. Weighing almost half a ton, the stibnite crystals were able to grow to such impressive lengths because they formed in a large underground cavity. You can see it up close in the Museum’s Mignone Halls of Gems and Minerals.

National #Museum of Natural #History: time for #travertine and #stibnite

The margin has been widening over the last few hours, but it’s still small enough to catch up.

4.25hrs left on the clock, #perovskite leading over #stibnite by under 50 votes

Stibnite vs Okenite (planetary science edition)

Stibnite may precipitate on the surface of Venus if there is sufficient antimony in the atmosphere. Minerals with high dielectric properties such as stibnite have been suggested as cause for the lower radar emissivity of certain regions but there are other options.

Okenite has not been detected on other planets but often occurs together with zeolites in geodes within basalt. Zeolites were detected on Mars.

#MinCup25 #Stibnite #Okenite

Hmmmmm.... I like how fluffy #okenite is - also fun fact: it turns gelatinous in HCl! (The things you learn from reading the whole #mindat page, lol. [Side note does Mindat have an @ over here?]) I think that would be fun to poke under a fume hood. (Alas I don't have any okenite or access to a fume hood.)

But I think I'm gonna go with #stibnite - kohl has been important for thousands of years, after all; plus, antimony has loads of uses both modern and ancient, iirc. (Don't ask me to name any right now lol. Migraine brain says mmm rocks.) And, stibnite *is* closely associated with arsenic - very similar symptoms if you ingest it, actually.

One wonders if using kohl was also poisoning oneself.... 🤔

It is not clear where Gutenberg sourced his stibnite, but it is clear that his invention created mass-produced books that revolutionised information transmission and set the stage for the Renaissance, Reformation, and humanist movements that underpin our modern world. Thanks #Stibnite! /4

Vote #Stibnite (Sb₂S₃) for #Mincup25 ⚒️🧪 because it was the likely source of antimony that literally wrote history. The chemical symbol for antimony is ‘Sb’ from ‘stibium’ the Latin for, you guessed it, #stibnite. Let's revisit a 🧵 from last year /1

#Okenite looks like something you see from the site of a surviving meteorite that you collect and put on the mantel of the fireplace... until it starts cutely purring.

You are also advised NOT to eat #Stibnite.

@MineralCup oh there is no competition between these! I just voted and #TeamStibnite is leading at twice the votes. I do have a fine piece of okenite that was terrifying to pack for a move. I shared a photo of very fine needle-like clusters just now in a reply to someone else here in Mastodon. Maybe look up the tags #Stibnite or #TeamStibnite or see my stream.

@silicatefondue Forever my favorite crystal is stibnite. I was fortunate to live close enough to Tucson for the annual Gem and Mineral Show venues. I have picked wonderful blades and clusters there. This piece I couldn’t afford but the vendor let me get close for a photograph. #TeamStibnite #Stibnite #Crystal #MinCup25 Go vote!

Repost from MinCup24: Antimony Tin Oxide scatters the wavelengths of infrared light emitted by warm humans. The antimony is often sourced from #stibnite. This material is being used to create fabric infrared invisibility cloaks!

Congratulations, #Perovskite. We couldn’t resist your Borg-like cubes. Farewell #Stibnite. Your wicked metallic blades shall retain their edge for next year.

#MinCup24 R3M1 #Perovskite versus #Stibnite

We cannot resist Perovskite’s Borg-like cubes, or its structural adaptation of new synthetic perovskite materials that promise futuristic technologies dreamed of in science fiction.

While Stibnite’s wicked metallic blades invoke thoughts of dangerous fantasy thrones, it’s the antimony in it that’s fatal.

Science fiction or fantasy? Choose.

Congratulations #stibnite! Your acicular dark-metallic crystals and dramatic flare have taken the day. Farewell #howlite. Your eerie bone-white, black-veined masses may have scared some voters.

#MinCup24 R2M3: #Howlite versus #Stibnite

Howlite is an opaque bone-white mineral marbled with black veins and a massive habit that earns it the nickname “white tourquise.” Soft, dark stibnite has a flare for the dramatic as kohl, an eyeliner used starting in 3000 BCE.

#Atacamite -used as a green pigment since antiquity on ancient Egyptian paintings, illuminated manuscripts, sculptures, oil paintings or here in ancient Buddhist Kizil Caves in China (3rd-8th century) pulls ahead of #Stibnite -used as kohl as cosmetics since ancient Egypt for my #MinCup24 art vote.

#MinCup24 ROUND 1 MATCH 7: #Stibnite vs #Atacamite

Are you rooting for kohl, responsible for dramatic eyes for eons ? Or do you favour the newcomer found everywhere from the Statue of Liberty to bloodworm jaws?

VOTE: https://www.mineralcup.org/2024/vote/r1m07
RESULTS: https://www.mineralcup.org/2024/results/r1m07

It’s a near-tie with just 5 votes separating #Stibnite and #Perovskite with just 2.5 hours left in the match.

The last few #MinCup23 wins have been secured by direct electioneering through personal networks. You want your mineral in the Finals? Bring in new voters to your side!

Almost halfway through the voting window for the second semi-final in this year's Mineral Cup and the Fortress of Solitude just has the lead over the Borg Cube, but the difference is so little as to be practically negligible.

How did I vote? Well, I like Star Trek, I like the Borg, but I also like to be contrary, so #Stibnite got my vote over #Perovskite in this case.
