Tell us about yourself!
Yes, other than the noise I think a cement mixer would work fine. I just found an instructable that shows exaclty what you want to do:https://www.instructables.com/id/Making-fake-sea-glass-at-home/
Thanks! I imaging you could do this with a working treadmill without having to modify it. I think if you clamped a board or some type of roller across the bottom of the belt to keep the bucket from rolling off, it would work fine. I do buy the more expensive bucket lids with a rubber seal to minimize the leaking.
Sorry, that was a bit misleading and I should have expanded on that. I put in sand and water and glass. After a few hours the sand starts to wear away the edges of the glass and small particles mix in with the sand. The sand starts to break down as well and turns a bit muddy. This is what I referred to as "slurry". I ended up rinsing the mix and using new sand several times. I imaging some other abrasive may work better, but I was worried about disposal. The dried slurry would have glass dust in it, so would be harmful if inhaled. I ended up letting it dry into a paste and disposing of it in the trash.
It's very easy to use and water based, very similar consistency to Elmer's glue. Since it is water based, I don't know how it would hold up outdoors, that is why I mentioned silocone in the other comment.
I dabble in fused glass also, mostly bottles and used window glass right now. Very nice works on your website! I just finished a gate with reclaimed redwood and fused wine bottle bottoms. It's a bit unusual, but it was fun to make:https://www.facebook.com/ocglassarts/posts/505335642924112
Thanks! I may experiment with an outdoor mosaic to catch the sun. I think I might need to use clear silicone as a bonding agent rather than the Weldbond though.
Thanks, your's is great. In case you're interested, I've cut hundreds of bottles over the years and have great luck with my old Fleming bottle cutter from the 70's. It has been re-released under the name G2 (looks like they are about $14 on amazon.com). It won't cut angles like you did, but for straight cuts and rings it works great and is fast. The tapping method is much faster than the other methods of breaking the score. It takes some practice, but here is how I do it: https://vimeo.com/207357008
