  Transcript: https://youtubetranscript.com/?v=32yYfTVIzBE https://youtubetranscript.com/?v=32yYfTVIzBE From the transcript (I dislike watching videos), it appears the video never discusses the chemicals involved - but I’m sure some of them are rather toxic. It is an old film, and when it was produced people didn’t see the toxicity of chemicals used in manufacturing processes as being as worthy as note as people do today - both environmental and workplace health/safety issues were less on people’s radar. Plus it obviously is marketing/PR for the manufacturer, and who wants to mention toxic chemicals in something like that?

    It's worth mentioning though that in general as our technology has gotten more exotic, so too the chemicals needed to manufacture it have gotten more toxic.

      Is there some underlying rule/"law" of fabricated products shrinking in scale requiring increasing energy density/control for their manufacture (more reactive chemistries) presumably to counter a general backdrop of entropy / entropy-density?

  10:37 has hydrochloric acid

    Sounds like hydrofluoric acid to me, which is even more dangerous. But seeing as you're making a vacuum chamber anyway, perhaps oxygen plasma could be substituted. https://en.wikipedia.org/wiki/Plasma_cleaning https://en.wikipedia.org/wiki/Plasma_cleaning
