In the UK PYREX cookware is always borosilicate. So it was a bit confusing to hear americans say how shit their "pyrex" glassware is.

Mind you, most of our oven proof glass is decent enough to be put in the oven and then dumped on a cold surface.

That's because a French company now owned by a US Private Equity firm, Arc International Cookware, owns the license for Europe, and as they have some pride, continue to make it with borosilicate.

It's available in the US under the "Arcuisine" brand.

I wonder if exploding cookware would get a British safety kitemark ?
