That's a real good question. I don't know if it can be done in a tumbler or not. Because real beach glass found on the beach has probably taken years to be made naturally. Yes I would put a little water in there too but I have no clue how long you would have to tumble it to get it to look like real beach glass.

Sorry I can't be of more help.

I made some in my tumbler. I put the glass pieces in, dumped in some sand (don't know how much. I didn't measure) filled it with water to about 3/4 full and ran it for about 2 days. Hope that helps. It's not very specific.

I think Smickerdoodle will know something on this. I think it was her that uses a tumbler sometime. And maybe CalamityJane.

Have you heard the noise a rock tumbler makes? My kids insistd on one and OHHHHHHHHHHHHHHHH my ears!!!!!

I do it in a cement mixer because I am usually doing large quantities, but you can do the same thing in a rock tumbler. I would just put in the glass and sand. I have found that you get the same results with a lot less time and a lot less mess than if you add water. I add about 4 parts glass to 1 part sand in mine. Hope this helps. Good luck!

I've heard use just water, and they will smooth up fine. I'm in the process of collecting a bunch of bottles, and when I get a pile, I will rent a cement mixer for a few hours and they will be done. Should have a ton of bottles..lol

Really dulcer? Just a few hours will do it? A friend and I are thinking of renting a cement mixer to make concrete stuff. Making beach glass would be a cool thing to do too.

It really takes longer with water than it does sand. I have tried it that way and it really takes longer than a few hours with the water. It takes only a couple of hours with the sand in the cement mixer. I usually check it after 2 hours.

Thank you for your replies & ideas! I really sort of figured it would take several days to get that 'beachy' look. I've used the tumbler a time or two, with just water and a drop of detergent, ran it about 30 minutes or so, and that did a wonderful job of cleaning up the glass, making it sparkling clean, and took off all the sharp edges, so it was safer to mosaic with. So now I think I will try the just sand method. Sure wish I had access to a cement mixer!
By the way, I've never run the tumbler with any rocks in it, so I have no idea what kind of noise that would make, but the glass with water made hardly any sound at all. Thank goodness!

Thanks snickerdoodle, I was wondering how it worked. I'll bet just water takes alot longer. I will make sure I just use sand when I get around to doing that..

I use a little rock tumbler I bought from Michael's...I put in the glass and beleive or not kitty litter and cover it all with water and then tumble it for about 24 hours...it is loud so leave it in the garage...the tumbler does not hold much but does the job...the glass is smooth and has that milky look like beach glass...except when it gets wet then it goes back to the original in this case brilliant green color...I use it in a planter with a purple tropical plant and it looks very pretty

Thanks for the tips Smick.
Someone on the mosaic and stained glass forum said they bought an electric ice cream maker at a YS and took out the paddle and they tip it at an angle to tumble stuff. Isn't that a riot? I'm going to keep my eyes peeled when its ys time again here.
Mary I think when "real" sea glass is wet it is colorful. Not that you find much of the real thing anymore since everyone is after it. But maybe Florida sea glass is different than Maine.

Imitation sea glass can be made in a tumbler using the shot (steel pieces of various sizes). This seems to be faster than using sand.

Be sure to specify that this is not real sea glass if you are planning on selling at craft shows, etc., as there is a huge difference in price and quality of real sea glass as opposed to man-made seaglass!
