His voice is so fucking robotic

[Holagrimola]

some good facts, but sadly you have a very boring way to speak...

[Maadhawk]

Sounds a great deal like this was a students presentation, probably uploaded by the teacher at the end.

[Jaybird196]

How are impurities removed, exactly?

[redjurij]

Thats all fine and dandy, this videos are interesting but voice is horrible. Like you are forced to read this or you will be expeled.

[Taleb Ismail]

Do you mean the voice is a human? OMG I thought it was a voice like google translation or something like that

[Roman Espla]

Arent we solids all super cool materials?=

[Vuk Ilic]

Okay well suck dick then

Pyrex is a trade mark for a borosilicate glass. The bulb shown as an example of Quartz glass is a plastic bulb with LEDs on a circuit board, and contains no quartz glass. They should have shown an automotive H4 bulb. A sentence or two on what hard glass is made of would have been useful. Oh, and that chemical formula for glass that was on the screen for about a half second made me laugh, though I couldn't read it that fast.

I wonder how much they got paid for this sad effort.
