How much tripoli should I put in my barrels? I have the Lortone 33B (rotary with two 3lb barrels).
Does tripoli change the color of the rocks? A couple of rocks looked darker after my experimental batches.
Later,

Hi,
It's mainly used as a pre-polish and will discolor stone (darken). There are several grades too.
Amounts depend on what & how much you're polishing (and which grade you you're using).

We have used tripoli as a polish for several years [obtained mostly from JBFC in Ca., grade ukn.], and have received compliment on our polish quality from people with vastly more experience than ours. In a 3lb. barrel, assuming that to be about a quart capacity, I would use 3 level tablespoons of polish. Any discoloration must be dependent on the mtl. being polished, ours is mostly quartz, and we haven't noticed it. We do let our polish run longer than most people I read here [generally ten days to two weeks], and do a long soap run after polish. Both polish and soap runs are generously padded with leather.

I've been using Tripoli as a preploish for a long time. I haven't noticed that it discolors rocks, but maybe I haven't been paying much attention. I've tried averything, lots, less, longer, shorter, and found a pretty good recipe for a nice prepolish.
I use the same amount as polishing compound, about half as much as regular grit, so in your case 1.5 Tbsp per barrel, maybe 2. It's run for 10 days. I found that it puts a darn near polish on rocks and makes the polish stage all the better.
