I have been trying to get a final polish on a batch of fluorite. Using my little vibrating tumbler, they just won't polish. Have tried both cerium oxide and tin oxide, neither have worked. Any ideas would help! Dave
The problem is that flourite is that it's too soft to tumble polish either in a vibe or rotary.
The best way I've found it to polish flourite on a buffer with a muslin wheel and ZAM. ZAM is a polish used to polish jewelry and softer stones. It's available at most rock shops and jewelry supply places.
I believe ZAM is made from Chrome oxide with a wax binder.

Fluorite is difficult to polish. I finally had success by using 60% mixed ceramic media with 40% fluorite (purchased from the RockShed) in a Mini-Sonic vibe turned down to 1/4 speed. I used about 1 tablespoon of AO polish in the 4lbs. hopper. I won't be tumbling fluorite again.
rockpickerforever: Cold here (56 degrees, brrr!) this morning, but it'll warm up soon enough! Expecting temps 20 to 25 degrees above normal today and tomorrow. And those Santa Ana winds. Not even a hint of a breeze right now...

headfullofrocks: Aaaahhhhh, Vancouver Island, Appx. 13deg Celsius. Grass is green, got some obsidian in cerium oxide tumbling away, and the sun is peeking through the clouds, can't ask for much better in the lap of geographical luxury. :
