Heat Resistant Tea & Coffee Mug

This Mug from Velleora Home Decor is made from borosilicate glass, the same material used for laboratory glassware, so it takes boiling water straight from a kettle without the risk of thermal shock that cracks ordinary glass.

Glass changes how a drink is served. Loose leaf tea shows its colour as it steeps, a layered latte shows its layers, and there is nothing for flavour to soak into between a coffee in the morning and a herbal tea at night - the failure of a well-used ceramic mug.

Ten designs and sizes are offered. The double wall keeps the outside comfortable to hold while the drink stays hot, and it prevents condensation with iced drinks in summer. It is dishwasher safe on a gentle cycle, though hand washing preserves clarity longer. Do not take it directly from a freezer to boiling water, and stop using it if it chips.
