Pure tin and submicron aluminum will look he same (very fine white powder). Coarser aluminum is fluffier looking (less dense) if that makes sense. Tin is reportedly the absolute best for vibe tumblers. Try it and see how it works. If her dad was old school it is more likely tin oxide. The better aluminum oxides are fairly recent products.

Thanks, it looks to be real fine, kinda like baby powder or even finer. I am just starting to tumble rocks, and I have a rotary tumbler will it work as good in the rotary as in the vibe?

Yes, it will work in rotary tumblers. However, if you ever positively id it, you might want to save it for "tougher" tumbles. I have found that sometimes certain things just don't get shiny in aluminum oxide, so I then resort to cerium, or as a last resort, to tin oxide. Tin oxide costs considerably more than aluminum oxide, so you might want to hold on to at least some of it.

Susan, depends on what grade of aluminum oxide.

If I send either or both of you a sample can you tell me for sure what it is?

I don't think you could tell one fine white polish from another by looking. If you want to send a little I'll compare to what I have but I really don't think it would do any good. I have CPP, Titanium Dioxide, 2 grades of Al Ox, Tin Ox, and Super Cerium at home.
