Is Borosilicate Glass Safe for Hot Drinks?
Can you drink coffee and tea from your Lagom glasses?
If you’ve ever hesitated before pouring boiling water into a glass, you’re not alone.
Traditional glass can crack under sudden temperature changes — which is why many people assume all glass behaves the same way. But borosilicate glass is different.
So, is borosilicate glass safe for hot drinks?
Yes — absolutely. And here’s why.
What Makes Borosilicate Glass Different?
Borosilicate glass is specially engineered to withstand extreme temperature changes. Unlike standard soda-lime glass (the type used in most everyday kitchenware), borosilicate contains boron trioxide, which dramatically reduces thermal expansion.
In simple terms:
✔ It resists cracking when exposed to boiling water
✔ It handles rapid temperature shifts
✔ It remains clear and durable over time
This is why borosilicate glass is used in laboratories, high-end cookware, and premium handmade drinkware
Can You Pour Boiling Water Into Borosilicate Glass?
Yes. Quality borosilicate glass is designed to handle boiling water safely.
That means you can confidently use it for:
Freshly brewed coffee
Loose-leaf tea
Herbal infusions
Hot chocolate
Matcha
Warm lemon water
For everyday rituals, it’s one of the most versatile materials available.
