inbound: lamentations of USians that pyrex isn't borosilicate glass anymore... 1. You can buy proper ISO 3585:1998 borosilicate glass kitchenware on amazon, just under another brands (Boral, Simax). 2. The borosilicate glass is softer than lime glass and thus prone to scratching and subsequent catastrophic failure. With laboratory glassware this isn't an issue as reagents aren't likely to contain sand grains.
