(... a much debated issue follows... You make your own decision... It will probably be a good one)
I use the same ceramics throughout the whole process. As long as you take the time to wash them in soapy water between grit changes. I put them in a Tupperware container (with a lid) and a squirt of Dawn. Then I shake-rattle-n-roll them until clean... seems to be no problem with that. If you are doing a burnish run before AND after the pre-polish stage... that should clean the ceramics just fine - just make sure you wash it off well with fresh clean water.
The larger ceramics are good for making up lost volume (after the 80 grit chews away at the rocks for a week or three), while the small ceramics are really good at cushioning. Vibratory tumblers get sort of choked-up when to many small ceramics are used (especially the new 2mm ceramic beads! However, the 2mm ceramics will work very well in a rotary tumbler).
I have been using small ceramic that I have purchased, but recently I have been using "home made" ceramic. My family and friends are saving all of their broken ceramic dish ware. I break it up by putting it into a 5 gallon bucket with a hammer and other heavy metal 🤘🏻objects then I shake the crap out of it. Then I tumble with some rough grit, and sort the small from the large pieces. Really good results on some apache tears and mahogany obsidian so far. First polish week ends Friday. Pretty excited to see how it goes on those as well.
