I've got some pieces of quartz. I can't tumble it with other stones, can I? Has anyone any experience with it? Can you give me a general formula for it (with time periods of each grit)? Some it 1-11/2" hex columns, some is just roundish (?). Any info helpful-Thanks!

Hi Shek, probably better to post this in the general section as that is read more. Anyway, there is nothing tricky about quartz, it is 7 on mohs hardness scale, so you can tumble it with anything of similar hardness -- agates, jaspers, amethyst, citrine, etcetera. Pretty standard tumble, just run it in coarse grind (with weekly cleanings and recharges of grit) until all the pits are gone and you are happy with shape -- this would usually be about a month. Then continue on with the finer grits for about a week each (adding plastic pellets to prevent chipping and bruising). You can find detailed tumbling guidelines on the main page for this website... here's a link, just scroll down and click on the tumbling section, pitfalls, etc. Good luck! www.rocktumblinghobby.com/ |

Pellets, pellets, pellets. I do a lot of Alaskan quartz, and have no problems with it as long as I use lots of plastic pellets in the final two stages.
