Abstract
An ice cube making machine has a plate with a plurality of cube forming locations on an outside surface of the plate. Each location has an outside surface generally flush with the outside surface of the plate and an inside surface exposed to the affects of refrigerant. The improvement comprises raised indicia on the outside surface of at least some of the cube forming locations for impressing distinctive markings into the ice cubes during formation thereof at these locations.
