How cool! I tried posting the link for you in SG, but I had already posted and it rejected my second message. What is up with that! I have a 3lb tumbler I use and love it. If I just want to smooth the edges, I use dish soap instead of frit, or whatever it's called. I could not find anywhere to put the amount of glass that I tumbled in a cememt mixer! Thanks for the link!

slow- whats the detergent for? Does it make any frothing bubbles?? I read in the directions you could use powder to burnish your rocks if there is a haze on them! daylily- when I tried the jar method described above I tried it. It really worked for me, but I have to say I love the convenience of the tumbler I got today! I used my tumbler for quite a while today doing some china, I had cut up. Now I have to make myself understand..now that its tumbled it will DEFEAT the purpose if I nip them before I use them..I swear I am so horrible about the pieces fitting just so that I'm gonna have to hide the leponitts (which I broke the wheel can you believe it!!!) and hook myself up to shock therapy!!!

Shireen, I don't know if you are still around and still looking, but I think you should pose this question at the Stained Glass and Mosaic forum at the Home part of Garden web forums. Good luck. Kathy

Vintage, I thought maybe a little explanation was needed. If you want to smooth the edges of your glass, just put the glass in the tumbler with water (about 1/2"-1" over the glass) and a drop of dish detergent. Let it run for 30-45 minutes. If you want the sea glass look, then you add the grit and must tumble it for quite a while. You can get the same results by placing your glass in a jar or plastic container and shake it or roll it around.
