What is high borosilicate glass and why is it different?

Most kitchen glassware is made from Kalk-Natron-Glas ^1{#ref-1}, which is cheaper but fragile. Hochwertiges Borosilikatglas is produced with silica and boron oxide, making it more heat-resistant and stronger.

It can handle extreme temperature changes, making it safe for ovens, microwaves, dishwashers, and freezers.
