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.
Slabs of manufactured ice at the Grimsby Ice Factory prior to being crushed, 1990. An icemaker, ice generator, or ice machine may refer to either a consumer device for making ice, found inside a home freezer; a stand-alone appliance for making ice, or an industrial machine for making ice on a large scale. The term "ice machine" usually refers ...
Pumpable ice can be produced in one of two ways: either by mixing crushed ice with a liquid or by freezing water within a liquid. The primary way is to manufacture commonly used forms of crystal solid ice, such as plate, tube, shell or flake ice, by crushing and mixing it with water. This mixture of different ice concentrations and particle
An ice spike is an ice formation, often in the shape of an inverted icicle, that projects upwards from the surface of a body of frozen water. Ice spikes created by natural processes on the surface of small bodies of frozen water have been reported for many decades, although their occurrence is quite rare.
An ice pack Shipment of vaccine in insulated box with gel packs An ice pack or gel pack is a portable bag filled with water, refrigerant gel , or liquid, meant to provide cooling. They can be divided into the reusable type, which works as a thermal mass and requires freezing, or the instant type, which cools itself down using chemicals but can ...

Ice resurfacers are generally composed of a snow container, hot water tanks, a wash water tank, the conditioner, and a board brush. An internal combustion engine or electric motor of the vehicle is responsible both for propelling the resurfacer and also powering the hydraulics that control the various functions, such as lowering the conditioner or raising the snow dump.
Its advantages include lower temperature than that of water ice and not leaving any residue (other than incidental frost from moisture in the atmosphere). It is useful for preserving frozen foods (such as ice cream) where mechanical cooling is unavailable. Dry ice sublimes at 194.7 K (−78.5 °C; −109.2 °F) at Earth atmospheric pressure.
