Use for working out scratches in glass by making a slurry the consistency of milk and with your finger and a soft cloth, dip and rub out the scratch. For deeper scratches you need to use a super fine silicone carbide grit sandpaper or diamond hand pads in various grit sizes to work out the scratch and then polish with the cerium. It takes a lot of work but is possible to accomplish. This cerium is light yellow cerium and is a high quality, optical grade. ...... It is an excellent polish for rocks in a tumbler (1 ounce per pound of stone) or vibratory lap (slurry). Use on a hard cloth buffing wheel, leather, or #8 canvas. Mix with water to the consistency of milk, paint on, polish your stones keeping a spray bottle handy to keep the surface damp....... This item is available in 1oz, 2oz, 4oz, 1/2 pound, and 1 pound re-sealable containers. ...... For use with faceting machines, sanding belts, lap disks, polishing heads for dremels. Leather or felt polishing tools are preferred, but cotton buffers will work well also. NOTE: Rock polishes are not magic dust. Stones must be ground properly to proper smoothness levels for the stones to accept polish or polishing will not take. Silicon Carbide stages coarse to medium to fine is the most common process although there are other processes available. The polish stage is the last step of several to many when rock polishing. It is expected you will be using proper lapidary equipment for the processes.

Bought this to polish out a scratch in an inherited Aussie opal ring of my mother's--my stepmother didn't react well to being told my mom's jewelry wasn't hers for the taking. The scratch was long, and deep enough to snag a fingernail dragged across the surface, so I didn't have high hopes. But it kept making me mad to see the scratch, so I figured I'd try this stuff out. Using mask, gloves and a Dremel on lowest setting with a felt pad, I mixed a little slurry and polished for about an hour, keeping the stone wet. I still have the scratch, but it's much reduced and I can no longer snag my fingernail. It'll probably take a few more hours of careful polishing, but I'm becoming hopeful I can erase the damage eventually.

Didn't realize how much of a warning label there was but as long as u use a teaspoon per cup of water, gloves and mask 😷 it works just as good on shining rocks as any polish. We enjoy doing the rocks one at a time instead of tumbling. This product does help with the final shine.
