All BODUM products are made to the highest standard.
The glass we use is Borosilicate glass which withstands
extremes of temperature, from -30 degrees centigrade to +530
degrees, and can be washed innumerable times. As with all
glass, care should be taken when using and whether washed
by hand or in a dishwasher should never be stacked on top of
other products or placed too close so that it can be knocked or
damaged. When storing glass products, again, space should be
chosen with care. Metal cutlery should never be used with glass.
Ice cubes should be added after the drink not into the empty
glass. Unfortunately, if the glass has been knocked or damaged
in some way and has a hairline fracture that is un-detectable
to the human eye, the next time hot water is poured into the
glass it can break or crack. This however is not a common
occurrence. In most cases the glass lasts for many years without
incurring any problems. Unfortunately there is no warranty on
the breakage to any glass items.
Double-Wall Glasses That Breathe.
We have improved our highly successful double-wall glass
line even further:
An added hydrophobic silicone vent at the bottom of each
glass now constantly equalizes the air pressure between
the two glass layers with the outside air pressure – no matter
if hot or cold liquids are poured into the glass. This makes for
significantly heightened product stability. All the other amazing
product features stay exactly the same – the glasses keep
hot drinks hot and cold drinks cold for a longer period of time.
They are cool to the touch and don't create any condensation
water on the outside of the glass. And on your coffee table,
we might add. After enjoying cocktails or even soups and
desserts, you just put the glasses in the dish washer – the vent
is only permeable to air, not to water.
The air pressure between the two glass layers is constantly
equalized with the outside air pressure.
