Mixing and Using Cerium Oxide to Polish your Glass Surfaces

[@productreviewspecialist]

Does this same concept apply to glass windows and at what RPM is best for a rotary polisher? I was told 2-3k but based on the heat factor of 75-100 degrees that speed would generate too much heat...like 120-140 degrees

[@hisglassworksinc]

same concept applies, but you’ll want your cerium a little thicker so it doesn’t flow off the glass surface as quickly. I would slow down the rotary polisher, yes.

when you do your pre polish with pumice, it takes a lot less time on the cerium polish

[@hisglassworksinc]

Yes, a pumice step will substantially reduce polish time. This is especially true when polishing on a lathe where you have less surface contact on the glass.

@@hisglassworksinc also on a flatbed...

[@hisglassworksinc]

@@heukelummer True, just more difficult to use pumice. It will work okay with a synthetic felt pad, but it really requires either a cork pad or a Polpur MJ wheel on a flat bed to work well for pumice.

@@hisglassworksinc i use a 60cm polyurethane flatwheel and have a little conical shape,so i dont have to apply to much pressure and use a plastic water bottle with a tiny hole to apply a constant water drip.

Just updated with a new video on Pumice.

75-100 °F or °C?

[@hisglassworksinc]

Farenheit, definitely. That hot in Celcius would break the glass.
