JoyJolt Serene Glasses

Yes, these glasses are microwave-safe. Because they are crafted from borosilicate glass, they are designed to withstand thermal shock, making them suitable for reheating beverages without issue.

The double-wall design creates a thermal barrier that significantly slows heat transfer compared to standard single-wall glass. While it won't keep coffee piping hot for hours like a vacuum-sealed thermos, it will keep your beverage at an enjoyable temperature for much longer than a traditional mug.

No, the outer layer of the glass remains cool to the touch even when filled with hot coffee or tea. This eliminates the need for a coaster or a handle, as the air pocket between the walls insulates your hands from the heat.

They are fully dishwasher safe. However, to maintain the clarity and longevity of the glass, we recommend placing them on the top rack and avoiding crowded loads to prevent accidental chipping.

While they are made of glass and should be handled with standard care, borosilicate glass is notably more durable and resistant to thermal shock than standard soda-lime glass. They are designed for everyday use, though they are not shatterproof.
