Sadly this seems to be yet another example of reliance on AI that doesn't know what it's talking about. Their information about chemical compositions and temperatures are quite wrong.....talc is magnesium silicate, not calcium carbonate..........and 260C is 500F, not 302F. There may well be other inconsistencies I didn't notice in one viewing but, hey, never let facts get in the way of a story. Still interesting to see the machinery.
