When I went to bermuda as a child we collected bits of class that had been rounded by the waves and sand. Anyone try this in a tumbler? What do I have to do different, if anything?

Great question. We have a jar full of glass that we've collected from the beaches in Maine, I never thought of trying to make some. Before I tie up a barrel I'd like to hear if anyone else has tried it.

I've made faux seaglass. I just busted up bunch of blue glass water bottles and dumped them in the tumbler in 220 grit for a week. Then, because it wasn't beat up enough to my liking (ie: still pretty clear with no frosting) I dumped them in 60 grit for another week and am happy with the results. I'd suggest if you're interested you might try the coarsest grit first, checking every couple of days until it gets to the point you like.

Glass can be tumbled and get excellent results. A good week with 60 grit will give seaglass, the full cycle with all grits and polish will give smooth lozenge type glass. Glass is primarily quartz and it behaves like it. You will find some glass that will not co-operate under any circumstances however. New beer bottle glass is an example. That needs to be heated first.

"That needs to be heated first". 100 degrees Celcius? 200 degrees? 500? A thousand? For a minute, hour or day?

I would go about 1300 degrees f. Let the glass glow, and let it cool normally. Another cool trick is to take glass marbles, heat them, and throw them in ice water. makes interesting patterns inside the marble.
