Topic: Cerium Oxide

[CultureVulture]

I have some Cerium Oxide powder. I was wondering if its possible to make polish from it that can be stored in a jar ready to use. What would be the best solution for this i.e just add water or is there any better long term suspension liquid.

from the point of view of creating a polishing medium, you might find that a metal polish would be the best carrier  -  but only make up what you need, when you need it.    Otherwise it might solidify in the meantime.    Is it essential you make it up in advance??      You might also try aluminium oxide instead of cerium  -  it is supposed to create a better polished finish, although I'm not entirely convinced.

Thankyou for the advice. :thup:

Wax is usual carrier for polish sold in stick form.

Since it is recommended to use cerium oxide in a water-based slurry, you could try mixing up a bit of that using distilled water and seeing if it goes moldy over time - though it's easy enough to mix, maybe storing it isn't necessary anyway.  Aluminum oxide is OK for an intermediate stage, but in my experience it isn't fine enough for the final polish and will leave a slight cloudiness on the glass.
