HAND-MADE, KILN-FIRED, BOROSILICATE GLASS: Borosilicate is the perfect glass for hot drinks. Compared to normal (soda-lime) glass, our borosilicate espresso mugs are much harder and stronger, they are more heat-resistant (enough to safely pour in boiling water!); and they stand up better to acidic drinks. Borosilicate is environmentally friendly, BPA-free and widely used in high-end cookware and drinkware.
