Claim:
1. An ice maker apparatus for an appliance comprising: a housing defining an interior volume; an ice tray rotatably coupled with the housing and including a metallic ice forming plate that has a bottom surface, a substantially planar top surface, and integrally defined metallic upstanding edges around the perimeter of the metallic ice forming plate; a containment wall that extends upward from the substantially planar top surface and along the upstanding edges of the metallic ice forming plate, and a grid that has at least one dividing wall that extends across the top surface between the containment wall on opposing sides of the metallic ice forming plate; wherein the containment wall includes a vertically angled longitudinal slot at a lower edge that receives the upstanding edges of the metallic ice forming plate such that the upstanding edges are positioned within the containment wall; a fluid line extending into the interior volume of the housing and having an outlet positioned above the ice tray and configured to dispense water over the top surface of the metallic ice forming plate to be retained by the containment wall and the grid; and a cooling source thermally coupled to the bottom surface of the metallic ice forming plate to freeze the water into a layer of ice on the ice forming plate, wherein the containment wall and the grid have a material with a lower thermal conductivity than the metallic ice forming plate, and wherein at least one substantially clear ice piece is formed in the ice tray.
