Our products are thermal and vacuum insulated. This means that an insulating storage container considerably increases the time during whose contents remain hotter or colder than the ambient temperature surrounding the flask. Invented by Sir James Dewar in 1892, isolation vacuum consists of two vials, placed inside one another joined by the neck or mouth. The space between the two vials is partially evacuated from air, creating an almost perfect and absent isolation of air molecules that would otherwise be transferring energy from one wall to another, thus significantly reducing energy transfer by conduction or convection. In other words: the best technology to keep your drink the way you prefer.

Ideally, after using your Glück, wash it with lukewarm water and mild soap using the little stick on the soft side to remove any residue left on the outside or inside. After washing, leave your Glück with the lid open to dry overnight. This process is necessary to maintain the perfect condition of your Glück. For deeper cleaning, fill the jar with boiling water, add 2 teaspoons of baking soda, close the jar, mix the solution with circular movements and let it stand overnight. The next morning, wash your Glück by doing the normal procedure with warm water and mild soap. Easy, right?
