Claim:
1. An ice maker of a domestic refrigerator, the ice maker comprising: an ice mold including (i) an electrically-conductive polymeric body having a convex bottom surface, and (ii) a plurality of cavities defined in the polymeric body, each cavity being sized to receive a quantity of fluid corresponding to a single ice cube, wherein the polymeric body is configured to contact the fluid when the fluid is received in the plurality of cavities, and a pair of electrodes engaged with the convex bottom surface of the polymeric body, the pair of electrodes being configured to be electrically-coupled to an electrical power supply to heat the polymeric body, wherein (i) the pair of electrodes and the polymeric body define an electrical circuit such that electrical current flows through the polymeric body when the electrical power supply is electrically-coupled with the pair of electrodes, (ii) the polymeric body has a first electrical conductivity at a first operating temperature, and (iii) the polymeric body has a second electrical conductivity that is less than the first electrical conductivity at a second operating temperature, the second operating temperature being greater than the first operating temperature, and wherein:
