About a two months ago, when my hubby and I was stricken with the tumbling fever, I purchased a 4-pack of grit from a guy on ebay. This was before I found this site and learned that not all grit is the same, especially polish. The listing on the item didn't tell me what kind of grit I was getting. All it said was 1lb. of course, medium, pre-polish and polish. When it finally arrived I noticed that each container had what looked like chemical element abbreviations on them. The course, medium and prepolish all had the abb. SiC. Which I think stands for silicon carbide. (Am I wrong here?) The polish however has me stumped. It has the letters CPP on it. Does anyone know what that stands for?

Greetings All,
Sure it's not COP, or Cerium Oxide Polish? I don't know what CPP would be, Cerium PrePolish?

Well my polish is white so if cerium is gray then it's probably not that. I found a site that had the chemical abbr. and cerium is Ce. So I'll keep looking. Eventually I'll use it all up and it won't matter anyway. But I thank you for the input.

Quite right, it is aluminum oxide..I had bought so much of it originally that I had forgotten...now thats why that sodalite never really polished well.

Another good topic. Does anybody know anything about "Iolox?" I'll summarize what I know: it's included in the Raytech 4-pack of grits to use with vibe tumblers and state 3 is "Iolox 50" prepolish. I could only find a little information between this board and various websites -- apparently it's a corunundum and it comes in several levels of fineness. I found a site there they were selling an 01 and an 05 Iolox. It turns a very dark brown/black color as it works, surprising because it's not unusually dark colored while dry. It does seem to give a very nice result in the prepolish phase. Seems to me that for those of us trying to do sapphires and rubies, maybe this product would do the job at earlier stages using the coarser types. Rocks of same hardness scratch each other so shouldn't corundum for corundum be a good bet? But I can't find out enough about it to see whether it is even used in barrel tumblers. I'd appreciate any information. Once again, I love this board.
