This is could be jamesp next endeavor. Thought this was pretty cool and interesting. About 6 miles north of home is a large concrete countertop studio. You should see their stuff. I have made them on a small scale. Never tried a newer product called 'jewelry grade concrete'. It may tumble polish. www.flickr.com/photos/67205364@N06/albums/72157635031954860/with/9484683304/These are wet, must polish on wheel or use varnish. Love tumbling concrete, big gas maker and slurry will cook yo hands. Texas concrete:  Georgia jasper/Portland  |

That’s a great way to reuse glass, almost as good as James’ way! LOL!

Smh. And yet when I tumbled concrete it turned into oatmeal lol. These modern day concrete crushers can make some nice tumble fodder. Especially if they have been crushing bridges and other structural concrete items. As you know there are all kinds of concrete. Some is super dense and best for lapidary work. And best if it has set for a long time. The concrete along the Rio Grande River in S Texas was rich in agate aggregate. Probably shouldn't take a sledge hammer to their sidewalks. There is a glass recycler not far from the concrete countertop studio. The recycler keeps it separated by color best they can. |

I found this and decided to polish it before i knew it was concrete. I has only been through the course grit  I have also contemplated mixing the bigger chunks from my saw water into some concrete expressly for tumbling fodder |

If it works well I may also use it as a way of tumbling smaller stones, not just the chunky bits from my tile saw. i have some set quikrete at the house I may toss a bit in the next batch of rough. |

They have started crushing so much concrete for re-cycled gravel sizes these days whyofquartz. Keep an eye out for concrete paved parking lots, road projects, etc. Warning, tumbling concrete makes concrete that will re-concrete to the bottom of your rotary if stop it too long. |
