Starting from a pure Ge sample, we attempt to make glass using chlorine gas and a microwave.

  • Thanks again to Turtle's Hoard for donating samples! www.turtlehoard.com/ They recycle laser crystals into jewellery, and have a lot of real fun and stunningly beautiful synthetic gems. Not sponsored or anything, they just reached out and donated samples after I did a bad job making good lithium niobate a few months ago- but their store is for sure worth checking out!
  • I learned recently that even alchemists thousands of years ago were aware of, and concerned with their reactions turning yellow when they weren't supposed to. So just think, you're part of a long line of people making accidental yellow chemicals and hating it! XD
  • Now make germanium transistors and make a quantum computer out of them to come up with the perfect cubane synthesis

    Formula: piss (l) + piss (s) -> glass (piss)
  • @jortand
    ah yes, the best measuring stick for toxicity, how close it is to arsenic.
  • @base6487
    As a Pole, I can guarantee that you can easily replace germanium with polonium for better results.

    4:00 ah, yes, the galactic lead cycle. Turns out the “great filter” is just the point where lead tech and intelligence reach equilibrium in a civilization. /s, mostly

    Instead of the pouring struggles, you could also use kiln paper (ceramic fiber paper) instead of a crucible. They cost $5 for 50 pieces, they are used for glass jewelry making. The blob of glass is formed on the kiln paper and after cooling can be easily removed from it.

    I'm surprised Tom likes chlorine when it's one of the most yellow elements on the periodic table.

    Mud wasp story: I had my regulators and lines off of my liquid oxygen cylinder last summer for a few days of maintenance downtime. 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.
  • @buzzzysin
    The wasp's nest genuinely gave me goosebumps

    "we've got quite a bit of glassware" Hey lad, you could have skipped all the science, you already had glass on the worktop
  • @Alloran
    You know you're into some high quality chemistry when you have a side of goulish wasp biology as a tangent. It is also comforting to at last know the fate of the shed spider. RIP.

    A wasps' nest MADE OUT OF MUD AND ZOMBIESPIDERS. Yeah, Australia is definitely out of my travel plans.

    Yes yes, feature request for Human 2.0 noted: - Make impervious to Lead and Cadmium. While we're at it, make compatible with other heavy metals as well.
  • @MaxWithTheSax
    Love it when a solid and a gas react to form a liquid.
  • @illomens2766
    That mustache really puts the German in Germanate
  • @msachin4885
    With such a portfolio in chlorine chemistry, you and Nile Red can pair up to accomplish some true breakthroughs in the shed-compatible piss and tar chemistry world
  • @GenosseRot
    I was not mentally prepared for the wasp nest excursion...
