Ground ice

Ice Ice ([imac]s), n. [OE. is, iis, AS. [=i]s; aksin to D. ijs, G. eis, OHG. [=i]s, Icel. [=i]ss, Sw. is, Dan. iis, and perh. to E. iron.] 1. Water or other fluid frozen or reduced to the solid state by cold; frozen water. It is a white or transparent colorless substance, crystalline, brittle, and viscoidal. Its specific gravity (0.92, that of water at 4[deg] C. being 1.0) being less than that of water, ice floats. [1913 Webster]

Note: Water freezes at 32[deg] F. or 0[deg] Cent., and ice melts at the same temperature. Ice owes its cooling properties to the large amount of heat required to melt it. [1913 Webster]

2. Concreted sugar. --Johnson. [1913 Webster]

3. Water, cream, custard, etc., sweetened, flavored, and artificially frozen. [1913 Webster]

4. Any substance having the appearance of ice; as, camphor ice. [1913 Webster]
