Glasses & Mugs

ThermoGlass thermal glass: 39 tumblers, mugs and bowls from 80 to 550 ml. Most have a double wall with air between the two layers of glass.

What the double wall does

• It does not burn the hand – the outer wall stays lukewarm even with boiling water inside.
• It does not sweat – no condensation on the outside with cold drinks, so no coaster needed.
• It holds temperature longer – the air insulates in both directions.
• The floating effect – the drink looks suspended in the glass, and latte or lemon tea layers show clearly.

Sizes

• 80–150 ml – espresso, dessert, small dip bowls.
• 200–300 ml – coffee, tea, cocktails.
• 400–550 ml – a large breakfast mug or a drinks tumbler.

The category also holds double-walled glass bowls (80 and 250 ml) for dessert, ice cream or a starter. Teapots from the same line are in glass teapots ThermoGlass, and the whole line in thermal glass.

Washing

All 39 items are dishwasher safe. When washing by hand, do not push a brush between the walls – the gap is sealed and needs no cleaning.

Frequently asked questions

Can water get between the walls?

No. The gap is sealed during manufacture, so water has no way in.

Does thermal glass crack with boiling water?

No, it takes temperature changes. Just avoid putting a hot glass on a cold wet surface.

Is it microwave safe?

Yes, according to the product pages. Check the specific model, though – bamboo and metal parts never go in a microwave.
