From Teaology comes an incredible new line of tea accessories that make a bold statement. Made of durable, heat resistant, mouth-blown borosilicate glass of the finest quality, the Infuso is the perfect tea brewing set. Our design is popular with flower blossom tea such as chrysanthemum blooming tea. 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, test tubes and other chemistry equipment. Avoid the aftertaste and flavor you get from plastic and metal kettles. This set comes with our famous Azzurro teapot and a set of 4 Luna Teacups. The teapot comes with an included stainless steel tea infuser to make gourmet loose leaf tea. It can be used on gas, electric, and coil type stovetops. It is lead free glass. The double-walled design of each Luna glass 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 glassware is dishwasher, microwave (excluding metal infusion parts) and freezer safe. Teapot measures 8" wide with handle and spout x 5.75" and 4.75" tall. 700ml/24oz volume. Each glass measures 2.5" wide and 1.5" tall and has a volume of 60ml.
