[[File:Cloudy ice cubes.jpg|thumb|Cloudy ice cubes]]
Commercially made ice cubes may be clear, compared to domestically made ice cubes. Cloudy ice cubes occur when water is frozen quickly, or when the water is high in dissolved solids. When water is cooled to its [[freezing point]], and ice starts to form, dissolved gases can no longer stay in solution and come out as microscopic bubbles. However, as ice floats in water, once there is enough ice to form a layer on the surface, the ice layer traps all bubbles within the ice cube. Commercial ice-makers use a flowing source of purified water to make ice with cooling elements at the bottom, allowing the bubbles to be washed away from the top as the cube grows.<ref>{{Cite book|url=https://books.google.com/books?id=ULbODQAAQBAJ&q=commercial+ice+cube&pg=PA341|title=Commercial Refrigeration for Air Conditioning Technicians|last=Wirz|first=Dick|date=2017-01-27|publisher=Cengage Learning|isbn=9781337514699|pages=341–2|language=en|access-date=November 1, 2020|archive-date=April 25, 2023|archive-url=https://web.archive.org/web/20230425113139/https://books.google.com/books?id=ULbODQAAQBAJ&q=commercial+ice+cube&pg=PA341|url-status=live}}</ref>
