Directional freezing can freeze water, from only one direction or side of a container, into clear ice. [ 1 ] [ 2 ] [ 3 ] Directional freezing in a domestic freezer can be done by putting water in a insulated container so that the water freezes from the top down, and removing before fully frozen, so that the minerals in the water are not frozen.
Clear ice refers to a solid precipitation which forms when air temperature is between 0 °C (32 °F) and −3 °C (27 °F) and there are supercooled, relatively large drops of water (from freezing fog). A rapid accretion and a slow dissipation of latent heat of fusion favor the formation of a transparent ice coating, without air or other ...
An electric blender. A blender (sometimes called a mixer or liquidiser in British English) is a kitchen and laboratory appliance used to mix, crush, purée or emulsify food and other substances. A stationary blender consists of a blender container with a rotating metal or plastic blade at the bottom, powered by an electric motor that is in the ...
Colder temperatures, lower liquid water content, and small droplets favors the forming of rime icing. Clear ice is glossy, clear, or translucent. Compared to rime ice, clear ice forms relatively slowly and tends to appear with warmer temperatures, higher liquid water contents, and larger droplets. Mixed ice is a mixture of rime and clear ice.

Black ice on a road in Germany. Black ice, sometimes called clear ice, is a coating of glaze ice on a surface, for example on streets or on lakes. The ice itself is not black, but visually transparent, allowing the often black road below to be seen through it and light to be transmitted. The typically low levels of noticeable ice pellets, snow ...
Osterizer single speed "beehive" blender. Osterizer is a brand which has been used by Oster Manufacturing for its line of blenders since 1946. History
Snow ice is white due to the presence of air bubbles. Black ice grows downward from the bottom of the existing ice surface. The growth rate of the ice is proportional to the rate that heat is transferred from the water below the ice surface to the air above the ice surface. [4] The total ice thickness can be approximated from Stefan's equation.
The refractive index of normal ice is 1.31 (from List of refractive indices). In general, an index of refraction is a complex number with real and imaginary parts, where the latter indicates the strength of absorption loss at a particular wavelength. In the visible part of the electromagnetic spectrum, the imaginary part of the refractive index ...
