ice-cube (n.)

"ice cut in small blocks for cooling drinks, etc.," 1902, from ice (n.) + cube (n.).

One of the newest plans for the economical use of artificial ice has recently been patented by Van der Weyde, of Holland. The invention is based on the fact that two smooth surfaces of freshly cut ice when brought into contact at a temperature below thirty-two degrees will unite firmly. At a higher temperature the junction yields to a blow, and the ice breaks into the original parts. Van der Weyde casts blocks of ice into small cubes, which are stamped with a trade mark. These cubes are joined into a larger cube of any desired weight and sent out for use. The mark is a guarantee that the ice is pure, and the small cubes, weighing an ounce each, are easily separated into a shape convenient for use.
