Description
PACKAGE INCLUDE – 1 piece 350 ml (12 ounces) double-walled glass cup. Temperature: – 20 °C to 150 °C. All glass items are fragile, so use and wash gently.
HIGH BOROSILICATE MATERIAL – Keep your hand cool while keep the coffee/tea hot. These glasses are made from ultra-light, heat-resistant borosilicate glass.
DOUBLE WALL DESIGN – Keeps the temperature of beverage hot or cold for a longer period of time while the outer glass wall remains comfortable to touch. Moreover, our mugs also keep iced coffee cold longer than a porcelain or ceramic cup.
Avoid extreme temperature changes:Â Borosilicate glass can handle hot and cold temperatures. However, it is still best to avoid subjecting it to abrupt temperature changes. For example, do not pour boiling water into a cold glass mug or place a hot mug directly on a cold surface. Gradual temperature changes are less likely to cause stress on the glass.
1.Can double glass be burned directly?
Double-layer glass can not be directly heated by open flame, because there is air in the middle compartment,
there is a risk of explosion in microwave and oven
2.Can high borosilicate glass pour 100 degree hot water directly?
High borosilicate heat-resistant glass, instant temperature difference -20℃ ~ 150℃, boiling water is 100℃,
because of the special material of heat-resistant glass, after placing the glassware in the refrigerator for 12 hours,
it is no problem to put it directly into boiling water
3.Is the double-layer glass product a vacuum? Why is there a hole at the bottom?
The double-layer glass products are not vacuum, and there is a vent hole at the bottom of the outer layer,
in order to exhaust the gas during the blowing process to prevent deformation and bursting. After the production is completed, the hole is sealed.
4.Can you microwave a double-wall mug?
Yes, you can microwave a borosilicate glass mug. Borosilicate is a special type of glassware that is resistant to acidic liquids and is microwave-safe.
