These people really didnt think about how people are going to pronounce their pigment? YInMn - what a monster of a name. In the olden days at least people gave colors great names that were easy to prounounce and provided them personality. Ultramarine, prussian blue.. Even vantablack has a nice rhythm. It's nice as techinical name, I guess, but I'd hope they have some better brand name they are going by.

There is a strong correlation between incidence of mercury amalgam and alzheimer's. Obviously correlation is not causation, but I'd still be wary of putting mercury in my body...
No there isn’t a correlation. Maybe you are thinking aluminum? Even then the data is weak. Mercury salts are corrosive, organomercury compounds are highly neurotoxic and elemental mercury is relatively non-toxic if ingested. The form of the element matters a lot.

Indium is comparable in abundance with gold, so it is indeed very rare. Indium is completely irreplaceable in LED's, especially in the LED's used for lighting, and also in other important semiconductor devices, e.g. in the GaN transistors that are now used in the latest miniaturized power bricks. Currently the largest quantity of indium is used for the transparent conductors required in all displays, from smartphones…
I would say, do not underestimate the value of art. The article described an artist that made is own paint from the pigment. He painted a depiction of an ancient bird, its absolutely beautiful. This use was not a waste of resources and will in fact last much much longer than any screen made in 2021. Its arguable that using precious resources for products that last less than 20 years, in many cases less than 5 years,…
However, if instead of using this pigment in a few valuable paintings, it would be used in a high number of ephemeral sketches done for practice, that would be a waste.
Nevertheless, the high price at which the pigment has been launched is good, because it will probably deter casual use.
Is this ok? >Yttrium is mostly dangerous in the working environment, due to the fact that damps and gasses can be inhaled with air. This can cause lung embolisms, especially during long-term exposure. Yttrium can also cause cancer with humans, as it enlarges the chances of lung cancer when it is inhaled. >Indium compounds are encountered rarely by most people. All indium compounds should be regarded as highly toxic.…
It just comes with the territory oddly enough...

Crayola is calling the crayon made with this color "Bluetiful", does that help? Wikipedia also refers to it as "Oregon Blue, Mas Blue, or Yin Min Blue" so I think it will be commonly called something else. Anyways, you're on HN, you know geeks shouldn't name things, but they do anyways. Think "XBox" as a perfect example.

There are other uses, too. AMD makes low profile (?) radeon pro cards like the WX2100 which are smaller and have lower power requirements than their consumer offerings. I got a used one off eBay for my tower, mostly because I wanted something AMD for linux usage with as low heat emission as possible, but honestly I really like the look of that blue too :) Even if I have a black boxy case with no fancy windows or anyt…
You might get some bargains on ebay for sure. But straight up it would make no sense for a non professional workload. You could get a AMD 5500 XT 4GB GDDR6 (WX2100 is 2GB GDDR5) for a similar ball park in price with 5x the bandwidth and a lot more graphical horse power for a gaming workload. And if heat is the concern it would be trivial to underclock and undervolt to get it quite chilly. You may have some special si…
And the 5500 XT has a TDP of 130 watts, vs 25 watts for the WX2100. The WX2100 is also smaller, and doesn't require additional power from the PSU, running entirely off the PCIe slot power.
Not that I'm saying it's great for gaming. But I'm running it on a IBM POWER processor which can't really play x86 games anyway, just open-source and java games (it can tank minecraft at 4k pretty nicely). It lacks an on-board accelerated GPU too, so going without isn't really an option.
I agree almost everyone should probably just get a better gaming card, but for the price this thing runs a 4k monitor great, has good video en/decoders, and a cool blue exterior ;)

Its oral LD50 was tested to be more than 5000mg/kg according to Shepherd Color Company's MSDS for Blue 10G513 (as it is known commercially). That's well into "non-toxic" as categorized by the EPA. For perspective, that's more than ten times less toxic than caffeine. So, probably pretty safe when used appropriately. I wouldn't go inhaling it, since any fine powder's not great for the lungs, but that shouldn't be news…
Wiki says this about cobalt: "it causes respiratory problems when inhaled. It also causes skin problems when touched; after nickel and chromium, cobalt is a major cause of contact dermatitis"
So for people looking for an example of something that's somewhat toxic, but much less toxic as a paint. Here you go, Cobalt Blue. The color this new can be substituted for. yeah the toxicities are different, but it's the same idea.
Earlier quoted context omitted.
Chemical reactions (such as forming it into a pigment) greatly change the biological effects substances have. For example, you probably shouldn't drink OH- or H2O2, even though it is made of the same atoms as water. Just because the pure elemental form is toxic doesn't make compounds with it toxic as well.
I don't think that is a very good example. A better example would be is there a safe compound with lead or arsenic or mercury (known toxic elements) you would want to take into your body?

I decided to pronounce it "Yelenmen"

Organic chemistry should probably be made mandatory as part of high school science education like physics. Parent looks like Exhibit A for anti-thiomersal hysteria.
I believe that the anti-thiomersal hysteria was quite justified. Even if thiomersal is more effective at killing bacteria than at killing humans, there are no doubts that it is also toxic for humans and for any other animals. While the thiomersal dose injected together with a vaccine is small enough so that in most cases it will not cause damages before being eliminated from the body, the risks are not negligible. To…
That's why it wasn't justified.
