From Teaology comes an incredible new line of glassware that makes a bold statement. Made of durable, heat resistant, mouth-blown borosilicate glass of the finest quality, the Coppia is perfect for tea and coffee lovers alike as well as cocktails and cold beverages. Borosilicate glass is stronger than common glass. It is shatter-resistant and resitant to high heat. It is the same glass used in making beakers and other chemistry equipment. The double-walled design insulates drinks at their ideal temperature and suspends drinks with a unique floating effect. The glass is condensation free and does not get hot to the touch when filled with hot beverages. The Coppia glasses are dishwasher, microwave and freezer safe. Set of 2 glasses. Measures 3" wide and 3" tall. 4 oz. volume.
