Review: Grit Number 2 for rocks tumbling (Medium 180.220 Carbide Grit) - The size of the containers are perfect for smaller tumbler that tumble up to 2 pounds of rocks at a time. For bigger tumblers one would need a bigger volume of grit than these containers. For what they are designed for though, they are about perfect. The grit is very good and works just like it should. There was no delay in the order and the product arrived quickly.

Steps 3 and 4 will require 1 tablespoon per lb. of rock. **Q: Is this good for etching glass? Has anyone tried it on glass?** A: Yes, it will work for tumbling glass. Using Step 2 will give a matte finish. Tumbler for a couple of days and check if are happy with the finish. You may have to tumble a couple more days to get the effect you like. To get a more clear look, continue with Step 3 grit (500 grit) and then possibly on to Step 4 (aluminum oxide). **Q: Is it 6 table spoons of grit for 3 pouns of rock? The video doesn't show them putting that amount in** A: Yes. We recommend 2 tbs per lb of rock for steps 1 and 2. 1 tbs per lb of rock for step 3 and then 1.5 tbs per lb of rock for step 4. **Q: can this be used in a sandblaster?** A: YES ## Customer Reviews ### ⭐⭐⭐⭐⭐ Grit Number 2 for rocks tumbling (Medium 180.220 Carbide Grit) *by T***S on May 8, 2026* The size of the containers are perfect for smaller tumbler that tumble up to 2 pounds of rocks at a time.
