I used two batches, one in each barrel. No idea what the stones are though as they came with the two tumblers (some stones today, and some came with the previous Lortone tumbler, which I'm using for jewelry only). I saw some nice jaspers, a small piece of rhodonite, and in the other one some pretty quartzes. Added 4 tablespoons of coarse grit, water to to almost cover the stones by 3/4 and a spoon of soda bicarbonate for the gasses that accumulate in the tumbler.
I guess I'll be seeing them next in about 7-8 days *sigh*. Sorry about the crappy pictures, but without a tripod I'm pretty much lost. And the tripod is in another place in the flat :D
I thought the tumbling process would make much more noise, and it would even interfere with my meditation sessions, but it's actually rather soothing, I have a feeling like I'm around a stone waterfall in a reiki office :) Even hubby doesn't get bothered with it (well not yet, anyway *grins*), so I guess for now it's all running in the living room. We'll see later on...
