In those short days, a mud wasp built a nest in the valve used to remove gaseous oxygen from the tank and I didn’t notice before hooking the regulator and lines back up to the tank. 8 months later I am still shooting bits of mud wasp nest out my torch face. Annoying little buggers.

I have giant Germanium lenses. They are used for thermal imaging cameras. As they have an extremely high refractive index of 4.5 and also refract the infrared light between 8-12μm really well. The 150mm f/1 front element is giant and heavy(several kilograms). It's made out of a massive ingot(boole) that's a giant, single chrystal. Which is grown in a special reactor (similar to silicon). It's then cut, polished and coated with anti reflective coatings for the specific wavelength. Some of the elements I have additionally have a diamond like hard carbon coating to protect the elements surface against weather and wear for example (my lens was part of a maritime imaging systems of a Russians oligarch super yacht). In fact there is a single video on KZbin that shows how these lenses are melted and cut. It's from a Russian manufacturer. The US destroys and recycles a lot of their Germanium. You can even buy lens scraps, which are usually cracked or broken in half on purpose in bulk. High performing lenses are export controlled. Yes, after a certain focal length... It's ITAR listed - for arms trade regulations. So I can't really cross the border with some of the stuff I own. I never expected it to be possible to make those at home... And I kinda feel like I asked for this plenty of times.

5:45 Germanium is directly underneath silicon, which we evolved to deal with being everywhere. Literally the sand/mud when our ancestors crawled out of the ocean was filled with silicon dioxide. Given that, it makes sense that our bodies evolved to tell the difference between carbon and silicon and ignore silicon. Si was everywhere, but hard to access, so we couldn't be dependent on it but also couldn't have a negative reaction to it, and so that ability to differentiate and ignore Si gives us the ability to do the same with Ge. Arsenic on the other hand, is directly under phosphorus and wasn't everywhere during our evolution. Since it wasn't widely available, there was no need to differentiate As from P and so our body takes in As and tries to use it as P, with horrendous results.

I think this was your most regulated response to unexpectedly yellow chemistry ever.

For thine determination and suffering by the cube, the gods of chemistry have blessed thee with a flawless synthesis. Cheers from a fellow (non-hobby) chemist :)

Hmm, suspicious .. first we get military IR flares, now we have glass that is see-through in IR ("mostly for military applications") ... What are you actually working on? :)

Molten Bismuth Germanate: the forbidden maple syrup

[@jacoblaitila7941]

no way I'm sleeping now man absolutely love your videos

[@lacklvster4512]

this video encapsulates why i love your channel, aphex twin and janky chemistry. btw i feel like richard's music just sounds like science, idk how else to describe it.

The sunglasses, infrared e&i needs a vb long neck and to scream FACK YEAH C

Oh my knight in shining armour is back to cure my boredom with a healthy dose of slapdash Aussie shed chemistry, bless you sire!!!

Your lead rant made me think you should do a video about fluoride😅

"we're coming out of summer so we've got like,... 8 clouds today". I snorted my drink at this. That's gold mate

YESSSS FINALY!!! FELLOW CHEMISTRY ENYOERS NEW VIDEO JUST DROPPED !!!!

Germanium also has some totally underexplored organic chemistry, especially aqueous organic chemistry, while Bismuth and possibly Germanium as well is interesting as an aqueous Lewis acid catalyst. Thanks for making this!

I love this unusual glass making arc Tom is going on.

I'm beginning to think that instead of putting in effort and resources to find ways to get rid of lead that we would do better to find ways to alter our biology so that lead is a nutrient instead of a toxin.

"Why do I suck at this?" Because you were using BBQ tongs! Bloody good effort, considering the equipment.

I would have thought about using needle nose pliers but hey
