Abstract: An ice shaping device with upper and lower mold parts with a mold cavity, the upper mold part being configured to move toward the lower mold part by gravity. The mold parts are formed of a material capable of rapidly conducting heat and together having a mass such that, starting at room temperature, the mold parts possess sufficient transferable heat to melt away portions of an ice chunk blank in contact with the upper and lower mold parts, the upper mold part having sufficient mass to apply a significant amount of pressure, under the force of gravity, to portions of the ice chunk blank in contact with the mold parts. One of the mold parts has a predetermined exterior periphery and the other of the mold parts has an extension configured to substantially surround and slidably receive the external periphery of the first mold part.
