Abstract: In a system for production of artisan ice, a freezer receives an artisan ice production unit comprising a water bath, a mold bottom and a mold top. The mold bottom and top define a mold that is partially immersed in the water bath when the water bath and mold are engaged and filled with water. The water bath may be heated by a heat source to control freezing of the water in the mold. The water bath, and mold top define lips above the level of water in the mold to prevent leakage of water from the mold and water bath. The mold bottoms may be stacked when the mold bottoms contain artisan ice portions for compact storage of the artisan ice portions.
