Polished Malachite Stalactite - Copper Crescent, Congo
*looks around*
Is
Is anyone gonna say it
malachite is a poisonous mineral. please do not fuck the malachite stalactite
@lizaleigh do you know any rock people that can confirm/deny because I am very curious and really don’t feel like getting into a conversation with my geophysicist brother that MAY somehow get back to the fact I saw a malachite that looked like a weird dildo.
…sadly, I am not on good enough terms with any of our partner geologists to just attach this to an email with the subject line: “EXPLAIN.” Although I think @mollisaurus is a mineral person. Thoughts?
oh geeze, i’m kinda rusty on minerals but malachite is just copper carbonate and is really common in both antique and modern jewelry so i think like if you were really gun-ho about it you could go ahead and put it wherever you want?
It’s really only a problem if you’re polishing or cutting it. The particles would be bad to breathe. It’s rather porous too, so I would worry about bacteria growing. Well, being literal anyway… Better to leave the poor thing alone. ._.
I mean it kinda depends on where you stick it because malachite does not like acidic environments very much and the malachite will degrade and also might dye your bits blue-green as the copper dissolves out.
So use a condom when fucking rocks is the takeaway here.
Oh my god guys it’s poisonous
It is super poisonous
There is a reason we do not use it in make up any more
Not even with a condom, do not fuck the rock
Try this one instead.
malachite literally explodes in water does it not?
I… no… I think you’re thinking of pure sodium?
Malachite is however water soluble, which really just means it will poison you quicker
This is both hilarious and cool as fuck because you’re getting all this information on minerals and rocks. You’re also watching people argue over wether or not you can fuck this rock
I go on hiatus for a week and come back to find tumblr molesting my post, but hey, at least we all learned something so yay tumblr, you just keep on being you.
I’m still not sure if I can fuck this rock.
I’m looking into it.
UPDATE:
Today in “I’m so sorry, coworkers, it’s for Tumblr,” I brought this post to the attention the science reporters at BuzzFeed. Dan Vergano did a some research and weighed in on the question “Can you use malachite as a dildo or is it toxic?”
The answer is “It’s probably fine, just wash it first and maybe use a bunch of lube.”
Oh man this got so much better than the last time I saw this post
This is my favourite. Science side of tumblr: asking the REAL questions
*biologist crashes through the underbrush* Ok so here’s the thing though Malachite is not poisonous to YOU. BUT fucking this stalactite will probably wreck your vaginal flora and leave you with a gruesome infection within a couple days. Want details? SO GLAD YOU ASKED, ‘CAUSE HERE THEY ARE. • Malachite is not copper oxide. It’s Cu2CO3(OH)2. Like most carbonates it’s water soluble– that’s how it became a stalactite in the first place! And technically any given chunk of “malachite” isn’t just malachite– it’s a mix of various copper carbonates & oxides. This will become important later. • When malachite dissolves it makes a bunch of copper (Cu++) ions. Cu++ is GREAT at killing bacteria and fungi– so good at it that sprays with Cu++ get used a lot as a spray in agriculture to stop plant disease. It takes such a large dose to harm larger organisms that copper sprays are used a lot in organic agriculture (like Bordeaux mixture). So bottom line, yes malachite is technically nontoxic to humans. But it kills bacteria when it dissolves and releases Cu++. • Malachite dissolves somewhat slowly in water– but vaginal secretions aren’t just any water. A healthy human vagina has a pH of 3.8-4.5 and a salinity of about 0.9%. It’s also warmer than your average underground cave at 37°C (or 98.5°F in American meat units). As luck would have it, acidity, salinity, and warmth all make malachite dissolve faster. • In other words, the human vagina dissolves malachite. • I have no deeper explanation for why human females can dissolve rocks with our genitals. It simply is. • Gonna to take a quick moment to point out that sex toys that dissolve when you use them are maybe not the best investment. • Anyway the key question now is “how fast does the human vagina dissolve malachite?” Are we talking geological timescale, a Nazis-in-Indiana-Jones situation, or something in between? If the reaction kinetics of dissolution are very slow, then there’s nothing to worry about. An encounter with a stalactite would have to last years for enough Cu++ to leach out to cause problems. If it’s quick then we’re in trouble. • Unfortunately it looks like nobody really knows. One of the best sources on how malachite dissolves & precipitates in water– an EPA document on how to avoid too much Cu++ in municipal drinking water systems– helpfully says “The kinetic constraints on the formation of these solids in water systems are largely unexplored” (p. 42) because end equilibrium points is all you need to run a city water system safely. In other words, the experiments that would tell us how fast malachite dissolves in various types of water just don’t exist because nobody’s ever needed to know before. So we’d better assume it’s going to happen reasonably quickly, #for safety. • So in best scientific fashion, we’re just going to bullshit our way ahead using what facts we DO have on hand: endpoint equlibria. • Is there any info out there telling us what equilibrium concentration of Cu++ we get in salty acidic water at body temperature? Almost! One J.F. Scaife published some great data on this back in 1957. TAKE IT AWAY, SCAIFE.
That orange box is how many moles of dissolved Cu++ Scaife got from sticking malachite in some water that had 0.171 moles NaCl/L (body salinity is about 0.154 moles NaCl/L so this is slightly less salty than people) at 30°C. He’s got no acidity in there, and again the salinity and temperature are slightly lower than people. But this is probably the closest we’re going to get to data on how malachite behaves in vaginas anytime soon, folks. From this we can take away that if you leave malachite alone in a vagina you’ll get AT LEAST 9.12 x 10^-4 moles/L, or 5.8 ppm, of Cu++ at equilibrium. • Recall from above that most “malachite” isn’t actually pure malachite, it’s a mix of various copper carbonates & oxides. The EPA document elaborates: “[T]raditional ‘eyeball’ identification of malachite by its blue-green color is extremely unreliable, because almost all cupric hydroxysulfates, hydroxycarbonates, hydroxychlorides, and even fresh cupric hydroxide can be some shade of blue-green. … Thus, the uncertainty in the computed copper concentration in equilibrium with malachite is at least about a factor of 2 … until further experimental data focusing on this problem is generated.” In other words, “do your math and then double how much Cu++ you think is going to be in the water, just in case.” So that gives us 11.6ppm Cu++, at equilibrium, with malachite in a (til now!) healthy vagina. • Next step: do we have any idea what happens to bacteria in acid conditions with copper? OH MY GOD WE TOTALLY DO. Gyawali et al 2011 checked this out in the context of “so what if we rinsed tomatoes with a solution of lactic acid and copper, because that would be a safe & organic way to get rid of E. coli?” So now this post has officially ruined stalactites, vaginas, and tomatoes.
^This would happen. These are the counts of 4 E. coli strains exposed to various levels of lactic acid & Cu++ for 8 hours. This table only shows the end counts but it represents the death of 99.7% of bacteria*. • Losing 99.7% of your vaginal flora is seriously bad news. You’re looking at really good odds of a yeast infection, bacterial vaginosis, and/or other infection issues. And that’s if you’re lucky enough to not be in the 4% of the population or so that’s sensitive to skin contact with copper. • The good news? Biochemically speaking, you’re probably ok to put it in your butt. It’s not as acidic or salty in there, plus there’s a huuuuuge stockpile of gut microbes right upstream that can quickly repopulate the colon after spelunking is complete. However this stalactite is not flared at the base so it is the wrong shape for putting in your butt. Do not put this stalactite in your butt. • This all looks like fun and games, but I think it’s really interesting that the internet’s mistake in concluding that this stalactite is fuckable is very similar to the mistake made by the Flint water management system. Hear me out. • Central to the Flint lead poisoning crisis is that authorities only looked at & tested Flint’s water in its central treatment plant before it went out through the pipes. Not after it went through the pipes. They did not consider what would happen biochemically as it went through the pipes and metals started dissolving. • Similarly, in concluding that the stalactite is fuckable, the internet only considered the stalactite itself. Not the biochemical processes that would happen to it as it, welp, went through the pipes. • Media frequently reports that the Flint River’s water is “corrosive,” leading many to believe the river is full of industrial waste. This ain’t the case. You’d need industry to fill a river with industrial waste, and industry left decades ago. That’s why Flint’s so poor. So what IS in the water? Road salt. Plain old stupid road salt. The old Detroit-based source didn’t have salt because it came from Lake Huron which has a large, mostly rural watershed. Meanwhile the Flint River runs through a lot of towns, making it slightly salty as everything melts down in spring. And as we recall from the stalactite experience, a little salt is all it takes to get metals to dissolve. • Information on this engineering problem was not coming through clearly from the engineering or chemistry sides. It took a biologist, pediatrician Mona Hanna-Attisha, to document the real-time results and provide the data to kick-start a high-level investigation. • Morals of the story: when dealing with a biological system pls consider asking a biologist, your vagina and/or city could depend on this • Pls use a condom when fucking any water-soluble material • Still don’t put the stalactite in your butt -3/10 do not recommend
OK, I haven’t reblogged this before now but the final post takes it to a whole new level and I can no longer resist.
IT GOT BETTER AND BETTER.
Long comment strand? Long comment strand. But SO worth the time to read, trust me.
Basically, don’t fuck the stalactite unless you want your nethers as wrecked as Flint, MI, is what I’m getting here.
This thread is WILD
Okay but what about with two condoms?
This is the best post I have read ever. Thanks for cheering me up Tumblr.

A better, more positive Tumblr
Since its founding in 2007, Tumblr has always been a place for wide open, creative self-expression at the heart of community and culture. To borrow from our founder David Karp, we’re proud to have inspired a generation of artists, writers, creators, curators, and crusaders to redefine our culture and to help empower individuality.
Over the past several months, and inspired by our storied past, we’ve given serious thought to who we want to be to our community moving forward and have been hard at work laying the foundation for a better Tumblr. We’ve realized that in order to continue to fulfill our promise and place in culture, especially as it evolves, we must change. Some of that change began with fostering more constructive dialogue among our community members. Today, we’re taking another step by no longer allowing adult content, including explicit sexual content and nudity (with some exceptions).
Let’s first be unequivocal about something that should not be confused with today’s policy change: posting anything that is harmful to minors, including child pornography, is abhorrent and has no place in our community. We’ve always had and always will have a zero tolerance policy for this type of content. To this end, we continuously invest in the enforcement of this policy, including industry-standard machine monitoring, a growing team of human moderators, and user tools that make it easy to report abuse. We also closely partner with the National Center for Missing and Exploited Children and the Internet Watch Foundation, two invaluable organizations at the forefront of protecting our children from abuse, and through these partnerships we report violations of this policy to law enforcement authorities. We can never prevent all bad actors from attempting to abuse our platform, but we make it our highest priority to keep the community as safe as possible.
So what is changing?
Posts that contain adult content will no longer be allowed on Tumblr, and we’ve updated our Community Guidelines to reflect this policy change. We recognize Tumblr is also a place to speak freely about topics like art, sex positivity, your relationships, your sexuality, and your personal journey. We want to make sure that we continue to foster this type of diversity of expression in the community, so our new policy strives to strike a balance.
Why are we doing this?
It is our continued, humble aspiration that Tumblr be a safe place for creative expression, self-discovery, and a deep sense of community. As Tumblr continues to grow and evolve, and our understanding of our impact on our world becomes clearer, we have a responsibility to consider that impact across different age groups, demographics, cultures, and mindsets. We spent considerable time weighing the pros and cons of expression in the community that includes adult content. In doing so, it became clear that without this content we have the opportunity to create a place where more people feel comfortable expressing themselves.
Bottom line: There are no shortage of sites on the internet that feature adult content. We will leave it to them and focus our efforts on creating the most welcoming environment possible for our community.
So what’s next?
Starting December 17, 2018, we will begin enforcing this new policy. Community members with content that is no longer permitted on Tumblr will get a heads up from us in advance and steps they can take to appeal or preserve their content outside the community if they so choose. All changes won’t happen overnight as something of this complexity takes time.
Another thing, filtering this type of content versus say, a political protest with nudity or the statue of David, is not simple at scale. We’re relying on automated tools to identify adult content and humans to help train and keep our systems in check. We know there will be mistakes, but we’ve done our best to create and enforce a policy that acknowledges the breadth of expression we see in the community.
Most importantly, we’re going to be as transparent as possible with you about the decisions we’re making and resources available to you, including more detailed information, product enhancements, and more content moderators to interface directly with the community and content.
Like you, we love Tumblr and what it’s come to mean for millions of people around the world. Our actions are out of love and hope for our community. We won’t always get this right, especially in the beginning, but we are determined to make your experience a positive one.

Well this is completely stupid....
Whyyy
Going to need some specifics dear
for the nsfw asks do every one ending in a 2 or a 6 pls!!
2. What are your kinks? Besides the obvious 😂 ? I'm really big on teasing, pushing my limits. I enjoy spanking both ways. Really though I haven't explored much but I have a fairly open mind and if it makes me tingle I'll probably try it out 😉
6. What are your favorite sex positions? Doggy, Missionary (ik ik but it allows my girls to get the attention I want ) and up against a wall (idk if there's a specific name)
12. What’s the kinkiest thing you’ve done? Oh gosh I'm sure there's something better but I had someone lick their mess clean. The look on their face was everything
16. Morning sex or nighttime sex? Definitely nighttime.
22. Biggest turn offs? Trying any kind of sexiness in the am, I'm the furthest thing from a morning person and I'll make you regret waking me up. Being a slob, I understand a plate or two not making it to the sink or whatever but those same plates, plus more in the same spot weeks later, nope nope nope you're gross. Being closed minded,
26. Spit or swallow? Swallow
32. Opinion on giving/receiving head? Love receiving, not fond of giving, so you have to be worth it. Not many have been.
36. Have you ever tasted yourself? Yup 😋
42. Have you ever taken someones virginity? A few
46. Can you squirt? 🤔🤔 I'm unsure
Someone come lay on my thighs please. ♥️
