Just finished 2nd round of rocks,but this time big ceramic pellets were in there. This time didn't get the shine,so cleaned everything just using small ceramic pellets like 1st tumble,does it matter? Plus added a little sugar and borax that I read some use.

I always run new ceramic pellets 24 hours (vibe tumbler) with fine grit as a 'break in' before putting them with stones. I also use different bowls for grit vs. polish... again with the vibe tumbler.

I'm a lazy tumbler! I grind with 60 grit for a month, wash the rocks, put them back into the tumbler and add rocks up to 1" of the top, add water and polish  and run it for another month sometimes 5 weeks. Unload and wash the rocks and load a new batch in. This has been my method for the last 25 years. I polish rocks for our wheel of fortune at our show. I run a 40lb and 2- 12lb tumblers 24/7.
