CRL Cerium Oxide Glass Polishing Powder 44 lb Bulk

• Premium cerium oxide polishing powder for fast stock removal
• Exceptional suspension qualities for recirculating slurry systems
• Easily cleaned from glass and equipment
• Zinc-free, no organic additives

All glass polishing and surface restoration systems that demand the highest degree of clarity use cerium oxide in the final process. CRL Cerium Oxide Compounds are refined from high-quality rare earth minerals and formulated for consistent performance across applications: hand pad spot repair, powered hand devices for scratch removal, mechanized scrubbers in mirror silvering lines, and final polishing in multi-stage edging and beveling equipment.

CRL Cerium Oxide Compounds deliver a uniform particle size (average 2.5–3.0 microns) and a high concentration of rare earth oxides for the brightest possible finish. The compound’s exceptional suspension quality and soft settling make it ideal for modern recirculating slurry systems and simplify cleaning of glass and equipment.

This durable polishing powder offers extended life in straight-line edging, beveling, and manual polishing. Proper concentration and temperature are critical: too much cerium oxide wastes product; too little reduces finish quality. Cerium oxide polishes by combined mechanical and chemical action—friction-generated heat activates the chemistry, so maintain a damp paste during polishing to prevent drying.

For recirculating slurry systems, measure slurry specific gravity in Degrees Baume with a hydrometer. Mix heated water (minimum 80°F / 30°C) with cerium oxide and test at the surface line. Recommended concentrations:

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

Maintain slurry temperature between 90°F and 105°F (32°C–40°C) for optimum polishing performance.
