Abstract
The seed crystal chambermay be located closer to the cold platethan the mold chamber. The seed crystal chambermay facilitate formation of a seed ice crystal from which the clear ice may form. By taking advantage of the lower thermal conductivity of water as compared to ice or aluminum, the seed crystal chambermay further discourage the water in the mold chamberfrom sub cooling and flash freezing as the seed crystal is being formed. Flash freezing occurs when water is subcooled below its freezing point and then exposed to an ice crystal, which causes the subcooled water to rapidly freeze. The seed crystal chambermay promote directional freezing in the mold chamber, which promotes clear ice. Thermal conductivity of ice is higher than that of water, which may facilitate freezing from the seed crystal chamberup through the mold chamberonce the seed crystal is formed.
