ABSTRACT:
A method and apparatus are disclosed for forming a monogrammed ice cube. The ice cube is formed by providing a die of conductive material with a shape which corresponds to the shape of a desired imprint to be formed in the cube. The die to conductively connected to a source of a coolant. With the die immersed in water, coolant is supplied to the die to cool it to a temperature below the freezing point of water. The water freezes around the die. The freezing of the water around the die is performed under conditions with the frozen water adjacent the die being clouded and the frozen water spaced from the die being clear. When the completed cube is formed, the clouded portion surrounding the imprint highlights the imprint when the cube is placed in a beverage.
