Definition (1) Thin, new ice on freshwater or saltwater, appearing dark in colour because of its transparency, which is a result of its columnar grain structure. On lakes, black ice is commonly overlain by white ice formed from refrozen snow or slush. (2) A popular alternative for glaze. A thin sheet of ice, relatively dark in appearance, may form when light rain or drizzle falls on a road surface that is at a temperature below 0 °C or, alternatively, when water already on the road surface subsequently freezes when the temperature thereof falls below freezing point. It may also be formed when supercooled fog droplets are intercepted by buildings, fences and vegetation.
