What is Borosilicate glass?

Borosilicate glass is a type of glass with the main ingredients of silica and boron oxide. Borosilicate glass is most well known for having very low thermal expansion, making it resistant to thermal shock, more so than any other common glass. It is also non-porous and Hypo-allergenic.

Borosilicate glass was first developed by German glassmaker Otto Schott in the late 19th century. Borosilicate glass is often used for high-quality beverage glassware and kitchenware (a popular brand name is Pyrex®). Borosilicate glassware has increased durability and has microwave and dishwasher compatibility. It contains no lead.

Why do you use “borosilicate” glass?

We use borosilicate glass because it is the strongest commercially available glass on the market, it is the same type of glass that your vintage glass coffee pot or your Pyrex® pie plate is made from.

I’ve seen reusable straws made from other materials, why should I go for glass? 

It’s true that reusable straws are available in other materials including metal and different qualities of glass. One downside to metal straws is that they conduct temperature so if you’re drinking something cold your straw will get cold… and the same goes for hot! They can also leave your taste buds with a lingering metallic taste which isn’t exactly savory. 

Can I use glass straws for hot drinks?

Absolutely. While you can’t use a plastic straw in a hot drink, a glass straw is perfectly safe—it won’t warp, crack, or melt.
