CRL C0653 Hi-Grade Cerium Oxide Polishing Powder - 44 lbs (20 kg)

CRL C0653 Hi-Grade Cerium Oxide Polishing Powder - 44 lbs (20 kg)

C.R. Laurence C0653 Hi-Grade Polishing Cerium Oxide - 44 Pounds (20 Kg) is a premium polishing compound designed for exceptional clarity in glass finishing and restoration. Formulated from high-quality rare earth minerals, this Cerium Oxide ensures fast stock removal while maintaining a uniform particle size of approximately 2.9 microns, leading to the brightest possible finish. This versatile compound is ideal for various applications, including hand pads for light surface cleanup, powered devices for scratch repair, and mechanized scrubbers in mirror silvering lines. It excels in recirculating slurry systems, given its remarkable suspension qualities, which allow for easy cleaning from glass and equipment. Importantly, C.R. Laurence Cerium Oxide contains no zinc, making it a safe choice for your projects. Optimal performance is achieved by carefully balancing concentration and temperature-maintaining slurry temperatures between 90ºF and 105ºF (32ºC to 40ºC) is essential. For light surface cleaning, a concentration of 1º Baume is recommended, while beveling and edging require 3º to 5º Baume. With C.R. Laurence C0653, you can confidently ensure a professional-grade polish that meets the highest industry standards.

Hi-Grade Polishing Cerium Oxide - 44 Pounds (20 Kg)

• Premium Cerium Oxide for Fast Stock Removal
• Exceptional Suspension Qualities
• Ideal for Recirculating Slurry Systems
• Easily Cleaned From Glass and Equipment
• Contains No Zinc

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 2.9 micron, 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 Cerium Oxide polishing process depends on 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.
