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 ### ⭐⭐⭐⭐⭐ Good Stuff Maynard *by J***N on 21 February 2026* Took a while to arrive...BUT this product is worth the wait. ### ⭐⭐⭐⭐⭐ Smooths them out *by M***T on 11 November 2023* Does a great job of smoothing out rocks, very consistent job. ### ⭐⭐⭐⭐⭐ Excellent Grit *by C***S on 15 April 2023* I use this grit in my rock vibratory and roller tumblers and have gotten excellent results every time. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/480386070-polly-plastics-rock-tumbler-media-grit-refill-medium-180-220](https://www.desertcart.tn/products/480386070-polly-plastics-rock-tumbler-media-grit-refill-medium-180-220) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-17*
