A clear ice maker having an ice tray with a thermally conductive cold plate, where the cold plate has a top surface and a bottom surface, with a thermoelectric cooling device thermally coupled to the bottom surface. Water is dispensed onto the top surface, and the bottom surface is cooled such that a portion of the water adjacent the top surface is frozen, to form a layer of ice. Then the ice tray is oscillated about a transverse axis of the ice tray, such that the water freezes in successive layers from the top surface of the cold plate upwards.
