bodum Pavina ダブルウォール保温グラス0.46L 2個セット 4560-10

High quality

I have used these for over 25 years with very little breakage which has always been due to mishandling. I just placed an order for some replacements as I just accidently knocked one over from my table onto my hardwood floor, and no surprise, it shattered. These glasses are NOT your typical inexpensive 'everyday' drinking glasses. They are fine glassware and need to be treated as such. However, I have never had an issue cleaning them in top rack my dishwasher provided they only touch the rack and NOT other items and are in the proper place so that they are not bounced around during washing. Being made of borosilicate glass they are more resistance to breakage than standard glass but not immune. That is why Bodum recommends never put ice in the glass first as if dropped in, being hard, along with sudden temperature extreme it could result in breakage. When cleaning from things like coffee or tea stains that occur with all glasses, I never use an abrasive powder like Bartenders Friend. Instead, I use something like Bon Ami, as abrasives can scratch glass that can lead to failure. I also use a non-stick scrubbing pad or a special 'brush' for deep glassware, rather than the harsher pads for the same reasons. Obviously, you need good judgement in a party atmosphere where they could suffer abuse or be dropped. The same goes when using them around children or 'adult children'. One Other 'trick' I have in my kitchen, which has hardwood floors is to place soft 'rubber'mats on the floor around counter areas. This not only creates a more comfortable working area for your feet, but it also reduces the likelihood of anything breaking when getting knocked off the counter or fallout out of a cabinet above, including these glasses. That has saved them several times for me as they bounce rather than break. With proper care these glasses have lasted me for many years without issue and could last a lifetime. Some cons about them, is that due to their shape they are easily knocked over if lightly struck near the top. This would be true for any glass of this shape. Since they have smooth sides, they can slip out of hands when wet as would any glass with smooth sides. The glasses are also have no warranty against breakage as their is no way that Bodum can determine if it was due to mishandling. But neather does any other fine glassware such as Waterford. Some reviewer had read made comments about being marketed as 'hand blown'. It actually refers to the manufacturing process which is to attach the chunk molten glass to some kind of a pipe and having air blown through the pipe, sometimes into an external, or sand mold to shape the molten glass into the glass shape. The other more common commercial process is to pour a chunk of molten glass into a 2 part mold that shapes it, and then take the mold apart to remove the the fully forned object. This also leaves an undesirible seam where the parts of the mold met, but is more suitable for mass production. Centuries ago craftsman made glassware by dipping a pipe into a pot of molten glass in the furnace and blew through the pipe turning it and using tools to shape the final piece. This process still used today as a hobby or for limited speciality glass objects. It also comes with a risk of silicosis for the craftsman, a lung disease as it allow glass particles of glass to get into the lungs often resulting in a shorter lifespan. Molten glass is actually never shaped by hand as its molten temperature is 2000°- 3000°F. I sincerly hope that this information can result in informed decision being made for the purchase and handling of this product to achieve satisfaction and a long life of it.

I tried these double-wall glasses for the first time a few months ago. They are so great that I wonder where they have been all my life. They are so great that I purchased the double-wall 8 ounce and large coffee mugs as well. They keep hot drinks hot and cold drinks cold for long periods. No ice needed for my iced coffee. I can put my morning coffee in the mug down for a while and it's still hot when I pick it up again. My only complaint is that they are smooth and not as easy to pick up and hold as my etched glasses. So if they can figure out how to make double-wall etched glasses I would appreciate it.

....still very fragile so handle with care.... I had a cheaper knockoff set of these before and they all either broke or leaked.... Not sealed very well. This new version from Bodum has a special valve that constantly equalizes the pressure between the two walls to adjust for temperatuve. And they claim it will never leak. We will see. Does seem like a better design. The silicone plug is dead center at the bottom. Despite being heavier than my last set, the glass is still pretty thin and this stuff cracks pretty easily if tapped the wrong way. (Very brittle) Bodum even recommends against putting ice cubes in them until they are full of liquid, because of the threat of breakage. The also said to avoid metal untensils to stir with. But if handled with care, they do the job. Keeping drinks hot or cold with no condensation. My only gripe is the stickers are hard to get off. And whatever you do, don't drop them. They will shatter into a million pieces. Very hard to clean up.

Excelente calidad como era de esperarse de un producto Bodum. Las bebidas se ven muy bien y al tacto el vaso siempre está a temperatura ambiente independiente de la temperatura del líquido en el vaso. Ampliamente recomendable
