Abstract
An ice support and storage tray includes one or more cavities having upwardly facing spherical surface portions that support spherical pieces of ice. The tray is preferably made of a material having a low thermal conductivity to reduce melting of the spherical pieces of ice. The spherical support surfaces minimize melting points that could otherwise cause the spherical pieces of ice to melt and develop irregular surface shapes. The ice tray may be used in a freezer having an ice maker that transports spheres of ice to the ice support cavities. The ice storage tray may be configured to permit removal of spheres of ice without tipping the tray upside down and/or twisting/deforming the tray.
