Bruce CunhaCerium Oxide Glass Polish
Hi
The facility I work at just closed our eyeglass manufacturing shop. One of the items that was being discarded was 40 pounds of Cerium Oxide glass polishing compound. This is a powder that is used for final eye glass polishing. It should be a good substance for polishing bezel's.
If anyone could use some, let me know bruce.cunha@charter.net

I also emailed you asking about how to get some, just in case I came through as spam.
Thanks

William D. WhiteHello Bruce & Mary Anne,
To tell you the truth, I've got about 4 lbs left from a 5 lb bag I bought 10 years ago! Others here will be interested though and it is no doubt a very fine grade. I would not recommend polishing bezels with CeO2. It is not not a suitable metal polish.

Old age setting in. I was looking at my watch bezel when I was typing. I meant the compound is for polishing the crystal.
For those that are interested. Send me your address and I will send out a USPS prepaid box full for the shipping cost of $4.95. I got it for free so only need to cover the shipping.
The web that Tom listed is what I used to polish scratches in my side window on my MG. It worked well on fine scratches. For a watch crystal, I would think you could hand polish them.
I looked on the container and it did not list if this is 90%, 95% or 99%. It was used for final polish of eye glasses, so it should be correct for glass crystals.

William D. WhiteBruce,
The best way to remove surface scratches from glass crystals is to get very dense felt or a piece of leather, maybe about a foot square, and fix it securely to a flat surface. Mix a thick slurry from the Cerium Oxide and water and put a generous amount in the middle of your work area. Start working the crystal around and unless it's very thin, don't be afraid to exert good pressure and speed...this process can take a little while. The slurry will begin to dry out after a short while at which time you should give it just enough mist to keep it from drying. If you get it too wet, it won't work well. Cerium Oxide works both mechanically and chemically and when you get the water balance just right, you'll notice a lot of drag and heat. CeO2 is magical stuff but remember that it's a final polish so don't expect miracles when it comes to glass with deep scratches.
Good Luck.
William

Claude GriffithIf it helps someone get some I will take a 1/2 lb rather than 1lb. Since the well is drying up might as well take a little less.

Larry BuchanI would like half a pound to if possible.
