## 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
