Quick Answer
To keep your borosilicate glass mug safe and long-lasting, avoid sudden temperature changes, hand wash it, and never use it in the oven or dishwasher.
Why thermal shock is the main risk
Borosilicate glass is heat-resistant, but it still has limits. The mug is rated for a temperature difference of 120°C, which means it can handle hot liquids like tea or coffee, but rapid changes—like pouring boiling water into a cold mug or placing a hot mug on a cold surface—can cause cracking or breakage.
This is why the manufacturer advises avoiding sudden heating or cooling. Even though the glass is durable, respecting this limit is the simplest way to extend its life.
Microwave vs. oven: what's allowed
The mug is marked as microwave-safe, so you can heat beverages in it. However, it is not safe for the oven or dishwasher. The dishwasher's high heat and strong detergents can stress the glass over time, and the oven's dry heat is beyond the mug's intended use range.
Stick to microwave reheating and hand washing to keep the mug in good condition.
