Yes, most models made of borosilicate glass are dishwasher-safe. However, it is advisable to place them in the top rack and avoid the hottest cycles. To preserve their shine and the lifespan of the seal, hand washing remains the best long-term option. In any case, always consult the manufacturer's recommendations.
This small silicone dot, found on models like the Bodum glass, is a hydrophobic valve. Its role is crucial: it allows the air trapped between the two walls to expand or contract with temperature changes without creating overpressure. This significantly reduces the risk of breakage while preventing water from seeping in. It's a kind of safety valve.
Bodum is the Danish brand that widely popularised the double-walled glass with its iconic Scandinavian design. Their products, such as the famous PAVINA or BISTRO ranges, are made from mouth-blown borosilicate glass, which is a mark of quality. The brand has truly set the industry standard. While their reputation is well-deserved, the final choice will always depend on your personal taste, the capacity you need, and your budget.
