CRL C0853 Cerium Oxide Polishing Powder - 44 lbs (20 kg)

C.R. Laurence C0853 Polishing Cerium Oxide - 44 Pounds (20 kg) is the premium choice for glass polishing and surface restoration, ensuring a high degree of clarity in every application. Crafted from the finest rare earth minerals, this Cerium Oxide compound is designed for quick stock removal and exceptional suspension qualities, making it ideal for recirculating slurry systems. With a uniform particle size averaging 1.0 - 1.5 microns, this product guarantees a brilliant finish, whether used with hand pads for light cleaning or mechanized scrubbers in mirror silvering lines. The unique formulation allows for easy cleaning from glass and equipment, enhancing operational efficiency. To achieve optimal results, maintain the slurry temperature between 90ºF and 105ºF (32ºC and 40ºC) and adjust the concentration based on specific gravity measured in Degrees Baume. For light surface cleaning, a 1º Baume mixture is sufficient, while beveling and edging require a concentration of 3º to 5º Baume. C.R. Laurence C0853 Polishing Cerium Oxide contains no zinc, ensuring safe use in various environments. This versatile compound not only polishes through mechanical and chemical action but also provides a finer glass surface finish with reduced subsurface roughness, making it an essential tool for building professionals and knowledgeable homeowners alike.

All glass polishing and surface restoration systems that demand the highest degree of clarity in the finished product use some form of Cerium Oxide in the final process. To reach that high degree of clarity requires the best product combined with the correct methods to reach the final goal. CRL Cerium Oxide Compounds are refined from the highest quality rare earth minerals available. CRL Cerium Oxide Compounds can be used with a hand pad for light surface cleanup, powered hand devices for scratch and surface repair, mechanized scrubbers in mirror silvering lines, or as the final polishing step in multi-stage edging and beveling equipment.


CRL Cerium Oxide Compounds maintain and deliver a uniform particle size, on average 1.0 - 1.5 microns, and a high concentration of rare earth oxides to provide the brightest possible finish in all applications. These compounds exhibit exceptional suspension quality, required for use in today's recirculating slurry systems. The added benefit of soft settling means glass and equipment are more easily cleaned and maintained.

The efficiency of the polishing cerium gives a finer glass surface finish with lower subsurface roughness. Two important variables: concentration and temperature. Too much Cerium Oxide is a waste of resources while too little impairs the quality of the end product.

Cerium Oxide compounds polish glass by a combination of mechanical and chemical action. The material must reach and maintain a certain temperature to stimulate the chemical reaction. The mechanical action employs felt pads or wheels. For surface restoration, the Cerium Oxide is mixed with water to form a thin paste that is applied directly to the glass surface. A damp felt pad or wheel is then used to agitate the paste. The friction of the wheel creates the heat needed to activate the polishing process. Too much heat will dry the paste, so care must be taken to keep the paste wet at all times.

For recirculating slurry systems, the concentration of Cerium Oxide in the water is based on the specific gravity of the slurry as measured in Degrees Baume, which is measured using a Hydrometer. Measure out the proper proportions of heated water (at least 80ºF/30ºC) and Cerium Oxide into a container and mix thoroughly. Place the Hydrometer into the mixture and take a reading at the surface line. For light surface cleaning such as pre-silvering, 1º Baume (1.6 oz. of Cerium per gallon of water or 11.8 grams per liter) is sufficient. For beveling and edging, a 3º to 5º Baume (4 to 7.2 oz. per gallon, or 29.7 to 53.7 grams per liter) is recommended. Slurry temperature should be maintained between 90ºF and 105ºF (32ºC and 40ºC) for optimum performance.
