Interesting video. Its nice that its stronger than regular glass,
but I
would have liked to see them push it until it did break.

Was this video made in 1987? It sure sounds and looks like it.

I would not be surprised. The product was developed in 1962.

It has properties that are not dissimilar to the original Pyrex, which
is
borosilicate glass (still available as cookware in Europe, but it's not
the
Pyrex sold for that purpose today in the US). "Gorilla glass" is
aluminosilicate.


Anchor Hocking still makes & sells borosilicate glass products in the
US. A search on their site gives 442 hits so you're wrong, yet again.

Not since 1998, Michael. Read what I said above. Pyrex cookware sold in
the
US today is tempered soda lime glass, and has been for over a decade.
That's
why Anchor Hocking doesn't call their glass products "Pyrex."

Once again, in your desperate quest to prove your superiority, you've
stuck
your foot in your mouth.

Check your facts, Michael. You should know better by now.


Our of curiosity, why isn't US Pyrex and similar borosilicate glass
anymore?

It's only the cookware. You can still get lab glassware labelled Pyrex
that's borosilicate.

I dunno why. Soda-lime glass probably is cheaper. Dow-Corning sold the
cookware business in the US to some other company in 1998.

I think it was Iggy that had a Pyrex baking dish explode. There are lots of
complaints about the new stuff.

I
can even buy the stuff in sheet from the glassworks half a mile from home
(useful when you break the oven door and want to replace it with something
decent..).

They make the real stuff in France. I considered importing it, but the
licensing and trademark thing is sewed up tight.



On the original topic, I'm less than impressed that the videos all seem to
show them comparing the new glass with ordinary soda-lime glass. That's a
bit
like comparing a Nimonic alloy with wood :-|

Yeah. I never heard of aluminosilicate glass before, but apparently it's
been around since the '60s.
