If you’ve ever browsed the Sucker collection of reusable straws, spoons and stirrers, you may have noticed they’re made from something called borosilicate glass. But what exactly is it, and why do we swear by it?
Let’s take a look at what makes this premium material not only safe and sustainable, but also super durable and stylish. Spoiler alert: not all glass is created equal.
What Is Borosilicate Glass?
Borosilicate glass is a type of glass made with silica and boron trioxide. Unlike regular (soda-lime) glass, it can withstand extreme temperature changes without cracking or shattering. That’s why it’s commonly used in laboratories, kitchens, and high-end drinkware.
It’s the gold standard of glass when it comes to strength, safety and sustainability.
Durable for Daily Use
One of the biggest myths about glass is that it’s too fragile to use every day. Not true with borosilicate.
-
Thermal Shock Resistant: It won’t crack when going from hot to cold (or vice versa).
-
Impact Resistant: While not unbreakable, it’s far tougher than regular glass and can handle minor drops and knocks.
-
Dishwasher Safe: Yep, all Sucker glass straws and spoons are safe to pop in the dishwasher.
This makes borosilicate perfect for reusable products that are meant to last.
Crystal Clear & Chemical-Free
Borosilicate glass doesn’t just perform well - it looks and feels amazing too:
-
Crystal Clarity: It stays clear, won’t cloud over time, and shows off your drink in all its glory.
-
No Nasties: It’s non-toxic, BPA-free, and doesn’t leach chemicals into your drink (unlike some plastics).
-
Non-Porous: It won’t absorb flavours, smells or colours, so every sip tastes just like it should.
Sustainably Superior
We’re all about sustainability here at Sucker, and borosilicate glass delivers:
-
Long Lifespan = Less waste.
-
Fully Recyclable at end of life.
-
Planet-Friendly Production: Made from natural materials with a lower environmental impact than many alternatives.
In short: you can feel good about choosing a Sucker straw or spoon—for your body, your drink, and the planet.
