Bodum's insulated glassware is made from durable
Borosilicate glass. Borosilicate glass is a strong heat-resistant glass that
weighs less than traditional glassware. Used to make scientific lab glass,
borosilicate glass (medical grade glass) is stronger than traditional
"soda-lime" glass and can be used for everything from drinkware to cookware.
Borosilicate glass substitutes boron oxide in place of the soda and lime used in
traditional glassware. The boron oxide acts as a glue holding the silicate
together and due to the small size of boron particles, the glass is held
together tighter, resulting in a stronger glass. Some people may perceive the
glass to be "thin" as they hold it, it is important to understand the difference
between borosilicate and soda lime glass. Borosilicate glass doesn't need to be
as thick as traditional glass to be just as strong. Borosilicate is simply a
different type of glass that is resistant to temperature swings and scratching.
Because the particles are held together so tightly, borosilicate glass is
dishwasher safe and will not become cloudy over time; you can rest assured that
after 100 cycles, the glass will be as clear as the day you bought it. Simply
treat it as you would any glass product and it will stand up to every day use.
Dishwasher & microwave safe.
Bodum's insulated, double wall glass is handmade by expert
artisans. Because this glass is mouth-blown, each one may have slight
differences in height, thickness & weight. Please use care when placing ice into
the glass to avoid fracturing the inner layer. Please also avoid using metal
spoons or placing the glass into a crowded dishwasher. These glasses will help
to keep hot drinks warmer and cool drinks cooler. For best results retaining
heat, pre-heat the glass before use. Dishwasher & microwave safe.
