Review: Good grit - This grit worked great for my first ever Columbia river rock polishing experiment. I didn't have enough stage 1 grit from the "starter" pack I originally purchased. I added another 3 TBSP to my tumbler and the rocks look great at stage 1
Review: Best rock tumbling grits on desertcart - I have been rock tumbling for over two years now and I have purchased this brand multiple times and will continue to be a return customer. The grits work exactly as expected for each stage of tumbling. Important notes: - Get the one that has the ceramic filler - not the plastics. The ceramic will last way longer and be better on your rocks. - Also - watch some YouTube videos on how to tumble rocks and switch between stages. There's some important tips to make sure you get the best results. Michigan Rocks YouTube channel has some great instructions on it. For the price and quality, couldn't be happier.

## Questions & Answers

**Q: how much do you put in a 1 lb Tumbler barrel?**
A: You would add 2 tablespoons per lb. of rock for both Stages 1 and Stage 2 (that is shown).  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
