Bodum's mouth blown Pavina drink-ware comes straight from the future. Every-time I take hold of one of these glasses and drink from them, it feels notably different from every other glass in my cupboard. The double-walled glass design offers excellent thermal insulation. My daily coffee stays hot MUCH longer than my regular ceramic mug. In fact, the last gulp of my coffee is always much hotter than I am used to. I don't think it will insulate for hours, but your drink should stay hot (or cold) for the duration of your sipping.

These Bodum glasses are made from Borosilicate glass, the same material that sophisticated lab equipment, telescopes, and nuclear processing equipment is made from. This same glass is also marketed under the brand names, Pyrex, Kimax, and Endural. Borosilicate glass is made up from silica, boric oxide, sodium oxide, potassium oxide, and potassium oxide. The addition of boron oxide (replacing soda and lime of typical glass) to borosilicate glass enables the special physical properties and further requires special manufacturing processes to create it. The stronger glass can be made much thinner than standard glass while maintaining the same or greater strength with complete heat and scratch resistance.

I would recommend these glasses to anybody. The design and fabrication of these glasses give them a unique hand-made appearance with precision robot made quality. When human tourists begin to travel into space, these will definitely be the glasses that they will drink from while orbiting the earth.

The borosilicate glass is amazingly clear, temperature, and scratch resistant. They are both dishwasher and microwave safe. The double-walled glasses appear and feel quite sturdy. I have read reports that these glasses will not survive drops to the counter or floor (especially the larger sizes), so a little bit of extra handling care is needed. The largest 21 ounce (Iced Tea) glasses are quite large and might not fit in some small dishwashers. Also, the base of this sized glass seems a little small compared to the overall height, making them unstable on uneven surfaces. All the other smaller sizes are perfectly proportioned and are simply beautiful.
