A frozen substance maker includes a heat pump, a cold plate, a mold base, a mold top, and an agitator. The cold plate is in thermal communication with the heat pump. The mold base is positioned on the cold plate. The mold base and the cold plate define a seed crystal chamber. The mold top is positioned on the mold base. The mold base and the mold top define a mold cavity in fluid communication with the seed crystal chamber. The mold top defines an overflow reservoir in fluid communication with the mold chamber. The agitator is located at least partially within the overflow reservoir.

Ice formation

The disclosure includes an apparatus and a method for forming a frozen substance using directional freezing. The apparatus includes a mold and a directional freezing assembly. The mold is structured with an interior chamber structured to contain a liquid substance. The directional freezing assembly includes a directional freezing probe and a cold plate. The directional freezing probe extends into the interior chamber of the mold and initiates directional freezing of the liquid substance surrounding the directional freezing probe. The cold plate is connected to the directional freezing probe outside of the mold and dissipates heat drawn from the directional freezing probe to a surrounding environment.
