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.

   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.

   2. Concreted sugar. --Johnson.

   3. Water, cream, custard, etc., sweetened, flavored, and
      artificially frozen.

   4. Any substance having the appearance of ice; as, camphor
      ice.

   {Ice house}, a close-covered pit or building for storing ice.
      

   {Ice machine} (Physics), a machine for making ice
      artificially, as by the production of a low temperature
      through the sudden expansion of a gas or vapor, or the
      rapid evaporation of a volatile liquid.

   {Ice master}. See {Ice pilot} (below).

   {Ice pack}, an irregular mass of broken and drifting ice.
