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?
Mercury amalgam (silver, tin, zinc, copper, etc) fillings.
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...

#83If I was working in a lab and my experiment turned a deep blue I'd say "cool!" and move on. I didn't know that discovering a new color was something meaningful.
I wonder who told these scientists "stop what you're doing you've just discovered a new pigment".

I kind of thought you were kidding, because nobody on earth cares what color their workstation/datacenter graphics card is... but indeed they are using YInMn blue: https://www.youtube.com/watch?v=GMXS1A2uBeE And made a video about how cool they are for putting certain paint on a graphics card. I will continue to be amused because people call Intel "team blue" and AMD "team red", but in this case AMD's product is blue…

Except for cooling a hot thing, you want a pigment that absorbs and radiates a lot in the far infrared (ie. acts like a black body)

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.
It is not? I had at least 2 years of organic chemistry at high school (Czechia).
In Germany it's 1 year of the final 2 year Chemistry elective, where most people instead choose Biology or Physics (and I think if you are on a language focused path you might not even have to do one of them).

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?
Sodium and Chlorine are both pretty nasty.

same in Egypt.

#88These 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.
I decided to pronounce it "Yelenmen"

#89Is 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.…
Dangerous pigments is old news to painters, and artists in general. Check out the book Artist Beware (Michael McCann). Pigments I used, and still use when I can get them, are the Cadmiums (red, yellow), flake white (lead oxide) and Naples yellow. All very poisonous.
A great influence on me as an artist, and a good friend, died prematurely almost certainly as a result of his exposure to dangerous materials. In his case, asbestos.

Isn't indium used everywhere in solder as a less toxic replacement for lead?
