CRL Cerium Oxide is a high-grade cerium oxide polishing compound for glass scratch removal, mirror bevel polishing, and final-edge finishing. Mixed with water into a paste or slurry, it provides fast stock removal and a bright optical finish without hardening. With uniform particle size (~2.9 micron) and a high concentration of rare-earth oxides, this compound delivers consistent results across hand pads, powered hand devices, mechanized scrubbers, and multi-stage edging equipment.

This formula offers exceptional suspension and soft settling—key differentiators for use in modern recirculating slurry systems—making glass and equipment easier to clean and maintain. Contains no zinc oxide and meets most disposal requirements.

Polishing efficiency depends on correct concentration and temperature. Cerium oxide acts by combined mechanical and chemical action: maintain a damp paste or slurry, agitate with felt pads or wheels to generate the heat needed for activation, and avoid drying the paste. For recirculating slurry systems, measure concentration with a hydrometer in Degrees Baume. Use heated water (at least 80ºF/30ºC) when mixing. Typical guidelines: 1º Baume (≈1.6 oz per gallon / 11.8 g per liter) for light pre-silvering cleanup; 3–5º Baume (≈4–7.2 oz per gallon / 29.7–53.7 g per liter) for beveling and edging. Maintain slurry temperature between 90ºF and 105ºF (32–40ºC) for optimum performance.
