Molten phosphorus is a viscid, oily, highly refractive liquid, which may be supercooled to 32° before solidification.
These are supercooled dewdrops that freeze as the temperature lowers; at -2.0C some of the water droplets were frozen.
supercooled water and on the discrimination between rain and snow.
supercooled liquid falls below that of the crystalline solid.
