Frequently Asked Questions

Q: What makes borosilicate glass superior to regular glass?

Borosilicate glass contains boron trioxide, which gives it a much lower coefficient of thermal expansion. This means it is far more resistant to thermal shock and chemical corrosion compared to standard soda-lime glass.

Q: Is the double-wall design dishwasher safe?

Yes, our high borosilicate mugs are designed for daily use and are generally dishwasher safe, though hand washing is recommended to extend the lifespan of the hand-blown seals.

Q: What is the purpose of the small hole at the bottom?

The small round hole is a critical engineering feature that balances the internal pressure between the two glass walls, preventing the mug from bursting during extreme temperature changes.

Q: Are these mugs suitable for commercial use in cafes?

Absolutely. They are specifically designed for professional environments, providing excellent insulation for lattes and cappuccinos while enhancing the visual presentation for customers.

Q: How does the "no sweat" feature work for cold drinks?

The vacuum layer between the double walls prevents condensation from forming on the outer surface, keeping your table dry and your grip secure even with ice-cold beverages.

Q: Can these be used for both hot and cold liquids?

Yes, the material's high thermal stability allows it to safely transition between hot coffee and iced smoothies without cracking or compromising the structure.
