Abstract
An ice maker adapted to make clear ice spheres includes a mold apparatus having a first mold portion and a second mold portion. The first and second mold portions further include mold cavity segments which define mold cavities when the mold apparatus is assembled in an ice forming position. A cooling source is in thermal communication with the first mold portion of the mold apparatus, such that water injected into the mold cavities is solidified in a directional manner from the first mold portion to the second mold portion to create a clear ice structure. Water is circulated, typically continuously, within the mold cavities to ensure clear ice is formed by injecting and simultaneously ejecting water from the mold cavities during ice formation.
