This may be the wrong board to post this on but Does anyone know what the polishing compound (part 4) is from Lortone's 4 part polishing kit? I couldn't find out from their website. Thanks Attachments:

Probably aluminum oxide.Should be safe to use for a polish step.Do you see AO in print?

I've heard they use titanium dioxide.

Thanks for the replies!
What you see there in the photo is all that's left of the original packaging which was a plastic tub like a 1 lb margarine container. I don't see any AO on the label. The material is a very fine white powder similar in texture and feel to cerium oxide, I don't have any AO or TD to compare it to.
Both my flat lap and felt wheel I use with cerium and don't want to mix different polishing compounds on them which is why I'd like to know what it is.

Titanium dioxide works pretty well in rotary tumblers. I found a small trash can full in my dad's store room. I thought it was a plaster mix of some kind until I found a label tag on one of the handles. It is a very fine, white powder. I don't know how well it would work on laps or buffs. Even if it doesn't work it won't hurt the rocks or the buff. You can always reload the buff with cerium or aluminum. It should be safe enough too. It is used primarily in paints and makeup.
