Abstract: A system able to make clear ice pieces of a wide range of sizes and shapes employing directional freezing includes an insulated cooler, containing ice molds of various shapes and sizes, configured to be placed in a freezing environment. The ice molds have holes at their bottoms to allow minerals and dissolved air to pass through during the freezing process. The ice molds are supported by separator frames. A ladder subsystem including two separator ladders allows the separator frames to be adjusted relative to the level of the mineral content of the water in establishing the clear ice pieces.
