Condensation bowls by Arnout Visser

Between the inner and the outer wall there is a space with water in it. If the bowl is filled with a  hot liquid, the water in the space evaporates and then condenses afterwards as drops on the inner side of the glass. If one then puts the bowl in the freezer, the drops freeze into flowers of ice.

The ornamentation is thus not static but is influenced by a physical process, set in motion by the user, and besides that gives a surprising experience to the senses. The bowls can be used with hot and cold liquids and have an insulating effect.
