Cerium Oxide Fine-Grade 100g

Cerium oxide is a rare earth mineral known for its exceptional glass polishing properties. It chemically reacts with glass at a microscopic level, smoothing imperfections and restoring clarity. This process effectively removes fine scratches, sanding marks, haziness, limescale, and chemical stains, making it widely used in glass restoration, gemstone polishing, and crystal finishing.gemstone polishing, and crystal finishing.

• Fine-Grade Cerium Oxide (2.5 microns, 95% TREO) is more refined, making it ideal for optical lenses, high-end glassware, gemstones, and crystals where a flawless finish is needed.
• High-Grade Cerium Oxide (3.5 microns, 85% TREO) is slightly coarser and better suited for general glass restoration, including car windshields, mirrors, and shower screens.

No, cerium oxide is safe for all glass types when used correctly. It polishes without scratching, but improper use—such as excessive pressure or using the wrong tools—can lead to unwanted results. Always follow the recommended polishing method.

Fine-grade cerium oxide is ideal for precision glass polishing, including:

• Optical glass & lenses
• Car windshields & windows
• Mirrors & glass tabletops
• Aquariums & watch crystals
• Fireplace glass & kitchen hobs

Yes! Fine-grade cerium oxide is perfect for polishing gemstones and crystals, including quartz, opal, tourmaline, and other semi-precious stones. It enhances clarity, removes light imperfections, and restores shine.

1. Mix cerium oxide powder with water to create a smooth paste.
2. Apply with a felt polishing pad on the surface.
3. Polish using a rotary tool at 1500–2500 RPM, keeping the glass temperature 30–50°C (86–122°F).
4. Work in sections, keeping the pad moving over the surface. Repeat the process as needed until the desired clarity is achieved.
5. Clean the glass thoroughly after polishing to remove any residue.

For best results, use a rotary tool or drill with a felt polishing pad. While hand application can clean glass, machine polishing is required to remove scratches and imperfections effectively.

Fine-grade cerium oxide is designed for light to moderate scratches. If a scratch catches your fingernail, it may require abrasive preparation before polishing for the best results.

Yes! Our non-toxic, zinc-free formula is safe for home, workshop, and professional use. However, we recommend using gloves and a dust mask when working with fine powders.

The amount needed depends on the project size:

• 50g (1.76 oz) → Polishes up to 4m², enough for at least 2 windshields or large glass panels
• 100g (3.52 oz) → Ideal for multiple glass surfaces, aquariums, or repeated use
• 250g (8.8 oz) → Suitable for larger restoration projects or professionals
• 1kg (2.2 lbs) → Best for bulk use, workshops, or industrial applications
