Chemex Coffee Mug

Yes, the double-walled borosilicate glass creates an insulating air pocket that retains heat significantly better than a standard single-walled ceramic mug. While it won't keep coffee piping hot for hours like a vacuum-sealed travel tumbler, it will maintain your drink's temperature for a standard morning coffee session.

Absolutely. The air gap between the inner and outer glass walls prevents the heat from transferring to the exterior, so you can comfortably hold the mug without a handle, even with very hot beverages.

Borosilicate glass is known for its thermal shock resistance and durability compared to standard soda-lime glass. While it is still glass and can break if dropped on a hard surface, it is designed to withstand the rigors of daily use and temperature fluctuations.

While the mug is durable, we recommend hand washing to preserve the clarity of the glass and prevent any potential damage from harsh dishwasher detergents or clanking against other dishes.

Yes, the 10 oz. capacity is perfectly sized for a standard pour-over serving, leaving just enough room at the top to prevent spills while allowing the coffee's aroma to collect.
