A method of releasing ice from a mold apparatus is disclosed which includes the steps of: providing a mold apparatus having a first mold portion including a concave depression and a liquid circulating manifold and a second mold portion having a concave depression; pivotally coupling to the first mold portion to the second mold portion such that the mold apparatus is operable between an ice forming position and an ice harvesting position; assembling the mold apparatus to the ice forming position such that the concave depressions abut to from a mold cavity; injecting water into the mold cavity; cooling the mold apparatus; forming at least one ice structure within the mold cavity; circulating a warm liquid medium in the liquid circulating manifold to warm the mold apparatus; disassembling the mold apparatus to the ice harvesting position; and releasing the at least one ice structure from the mold apparatus.
