The other day I was interrogating a pair of old timers who owned a lapidary shop for 30 years. They won a number of tumbling contests in the local rock club and I've seen a lot of obsidian they tumbled that looks really nice. Their secret? ... newspaper. They would add enough newspaper to make a pulpy slurry that would hold the grit, yet cushion the stones. They used rotary machines for the first two cycles then went to a vibrating machine for pre-polish and polish. I have to question newspaper for the polish stage because it is somewhat abrasive and might prevent a mirror polish, but I can't argue with the results I saw. Denzil and Elaine Hammer, owners of Artistic Jewelry of Fruit Heights, Utah are my pals and they retired a couple years ago. Really, newspaper? Like you said, you can't argue with results. Plus, old-timers have experience and knowledge on their side!

Yep, when they told me that I had flashbacks to years ago when I ruined the polish on my eyeglasses by using paper towels to wipe them with. Many types of paper can be fairly abrasive apparently. But, I can tell you that the polish on their obsidian rivaled some of the best you see here on RTH. Go figure.
