Hi All,
I have a few pots that I scratched up a little during the grinding step when I was cleaning up the glazed edges of a finished piece. I don't want to put them out for sale when I know they are damaged, but I was wondering if there was a good way to polish those spots up. Do any of you try to reclaim pots that have been scratched up on the diamond grinder. Got any tips that I might use to make these pieces look like new?
Cheers,
Marie

Marie,
Glass makers use Cerium Oxide as a polishing agent. I have never tried it, but I should as I certainly have scratched up some otherwise decent pieces the same way.

Someone that does lapidary ought to be able to erase shallow scratching. Perhaps your dentist has the tools (laser?) and capability.
Tin oxide is used for polishing in lapidary. Chrome oxide is used to create razor sharp and smooth surfaces.

Thanks for the great ideas guys! I already tried the nail polish trick - it does a nice job even though it feels like cheating.  I looked into the cerium oxide, and it looks like these scratches are too deep for that to work. The lapidary sounds like it would work, now I just need access to one. I need to probably be more mindful on the grinder so I don't create extra problems for myself! Thanks, Marie |

Hi Marie,
Unfortunately, your only chance is to do a step-wise (going progressively finer) polishing using a diamond paste compound on some canvas or felt pads. Given that the crystalline glazes are so thin, you are likely only going to create a bare spot on the vessel body.
Using a small amount of UV resistant acrylic polish or spray is probably the easier option. You could try doing this, carefully, and then buffing using a 0.1um colloidal silica polishing compound or something similar to make it unnoticeable.
