ABSTRACT:
A clear ice maker has an improved stationary open-top water tray comprising a plastic frame with metal inserts in the tray side, end and bottom walls for containing a predetermined quantity of water. The tray receives a removable grid having a plurality of open-bottom, open-top ice mold cavities and flexible filler means between the cavities to displace substantially all of the water into the cavities when the grid is in the tray. The tray side and end metal inserts have heaters thereon which are activated prior to ice harvest to melt the ice bond between the grid and tray permitting release of the grid. The tray bottom wall metal insert has continuously energized heater means thereon and is formed to provide a raised area beneath each grid cavity, thereby preventing freezing through the bottom of the grid cavities.
