These days, a teacup doesn't necessarily have to be made of porcelain - WMF also makes it from heat-resistant borosilicate glass. The advantage: The Heat Resistant Glass can withstand high temperatures and does not crack when hot drinks are poured into cool glasses or on ice cubes. The visual effect is also nice, as the color of the tea comes into its own through the glass. The attached handle is also made of sturdy glass and lies securely in the hand without getting hot. You can serve the tea in style on the saucers made of matt Cromargan®.
