CRL Cerium Oxide (SKU C0301) is a high-grade cerium oxide polishing compound formulated for glass scratch removal, mirror bevel polishing, and final finishing in edging and beveling equipment. Mix with water to form a paste or slurry. The compound maintains a uniform particle size (average 2.9 micron) and a high concentration of rare earth oxides to deliver a bright, consistent finish. Its exceptional suspension properties and soft settling make it compatible with recirculating slurry systems and easier to clean from glass and equipment. Contains no zinc oxide and meets most local disposal ordinances.

This compound works for light surface cleanup with a hand pad, powered hand devices for scratch repair, mechanized mirror silvering lines, or as the final polishing step in multi-stage processes. Cerium oxide polishes by combined mechanical and chemical action: a thin paste is agitated with a damp felt pad or wheel to generate the heat needed to activate the chemical reaction. Maintain the paste wet—excessive heat will dry it and reduce effectiveness.

For recirculating slurry systems, measure slurry concentration in Degrees Baume using a hydrometer and use heated water (at least 80ºF / 30ºC) when mixing. Typical guidelines:

• Light surface cleaning / pre-silvering: 1º Baume (1.6 oz cerium per gallon or 11.8 g/L)
• Beveling and edging: 3º–5º Baume (4–7.2 oz per gallon or 29.7–53.7 g/L)

Maintain slurry temperature between 90ºF and 105ºF (32ºC–40ºC) for optimum polishing performance. Proper concentration and temperature are critical: too much material wastes resources; too little reduces finish quality.
