A device has a means of creating ice or condensation 10 on its outer surface. Preferably, the device controls the formation of ice or condensation on the outer surface of an article such as a beverage dispense font The device comprises a first component 2, having an outer surface 2a and an inner surface 2b, and a second component 4 in thermal contact with the inner surface of the first component. The first component has a lower thermal conductivity than the second component. Cooling means, such as a thermoelectric wafer or coolant circulating pipes 8 attached or embedded in the second component, are provided for cooling the second component to create ice or condensation on the outer surface of the first component. In use, ice or condensation forms preferentially on a selected area of the outer surface of the device, where the first and second components are in thermal contact, when the second component is cooled. In a further aspect, the first component comprises thermally conductive plastics. The outer surface of the first component may be chromium plated so as to give the appearance of a device made from metal.
