Handmade from Borosilicate glass
Borosilicate glass is well known for its durability and resistance to thermal shock. Having constituents including silica and boron oxide, borosilicate glass has a very low coefficient of thermal expansion and a melting point much higher than ordinary glass (over 815 degrees C). It contains no lead. With its superior durability, chemical and heat resistance, borosilicate glass is often used for scientific laboratory equipment, optical and lighting applications, as well as in glass cookware.
Care: These glasses are dishwasher safe. They will be unaffected by the heat or detergent in the dishwasher, however care should be taken as the glasses are lightweight and can possibly be lifted from the rack by water jets from below.
Malfatti glassware can be heated in a microwave oven or in a hot water bath. The glass and liquid will become hot but there should be no danger to the glass itself from the heat. Never heat the glass over direct heat on a stovetop.
While the glasses are resistant to thermal shock, they are thin-walled. Therefore we recommend adding ice only after liquid is already in the glass and adding the ice by hand rather than from a refrigerator's ice machine.
