Thanks...good to know. We used to give that to chickens to help them digest food. Didn't realize they used it to polish rocks, too.
Well, it’s just something I had on hand. Because we have chickens and it does help them digest food.
I just “repurposed” it on a whim. Worked a lot better than any of the purpose-made stuff that came in the kit with the tumbler. Also worked better than clean play sand from the kids’ sandbox.
