Cerium compounds are used in the manufacture of glass, both as a component and as a decolorizer. The oxide is finding increased use as a glass polishing agent instead of rouge, for it polishes much faster than rouge. Cerium, with other rare earths, is used in carbon-arc lighting, especially in …

Liquid cerium is dense at atmospheric pressure than its solid form. Chemical Characteristics. Cerium is tarnished when exposed to air. At 150 O C, cerium readily burns in air and form pale yellow cerium (IV) oxide which is also known as ceria. With hydrogen gas it is reduced to cerium (III) oxide.

Cerium oxide was one of the first polishes to be widely used in rock tumbling.It is the "polish of choice" for many people who do rock tumbling and all types of lapidary work. Cerium oxide produces a bright polish on agate, jasper, quartz, petrified wood, obsidian, feldspar minerals and just about every rock, mineral, and glass that is processed in a rock tumbler.
