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.
