So these storage units belonged to a serious jeweler. He had an amazing collection of material. He offered me a deal on a box of what I thought were tumbling ceramics that I couldn't refuse, this was a while ago. My typical Rockshed cut cylinders are wearing down so I decided to break these out and give them a go. I did smooth the edges for a day in the vibe with some 220 SiC. I ran lot-o loads with a hand full of flats lot of media (and the leftover boring botswana pcs I've added to my smalls/ceramics collection) Nothing came out looking very good. The original cylinders lost their shine, as did the other bots/agate smalls. I'm wondering if these have some other rough stuff embedded that were meant for tumbling metal jewelry pcs or something. Can't ask the original owner, they've moved on.
Seems like I grabbed some one other time and wasn't happy with the results. Definitely not plastic.
Anyone happen to recognize these? ear plugs for scale.

Never seen them before but they should do the trick. Only thing I could see would be an issue is the small end getting wedged onto voids or pits. That wouldn’t stop me from using them lol.

My quick look in a tumbling media search indicate these are for metal deburring, etc. I believe(foggy memory) that I have read articles that indicate that ceramic media can not only be of different hardness's but may also contain other inclusions where the media is simply the carrier. If you have a good quantity of this material I would use it in the first few steps and then do the 1000 and polish stage with the Rock Shed media and see how that works.

They kind of look like these. Coffee not doing the trick this morning, seems to be linking to it's own thread...
