Found a nice 3/4 inch thick slab of soft tempered glass at the salvage office supply. Couple of taps w/the hammer threw the pieces in a steel bucket and heated them Dumped the hot glass in a bucket of cold water Fractures throughout make breaking to tumble size pieces easy

flashback! when I was in jr high during the dinosaur ages we used to make fried marble jewelry. heated marbles in frying pan, threw ice on them and then made necklaces and bracelets out of the ones that didn't shatter by gluing on jewelry findings. It was a popular craft for a few years. your posts are always interesting.

Man... that was a nice piece of glass!! My dad builds coffee tables out of elk and moose antlers and that would have went very nicely on top of one!!
On the other hand... I bet you get some nice little tumbles out of it!!!
I am going to have to try the marble deal!!!

That was a 3 piece pedestal with those of this plates bolted together. I make tables too, and people call me to come get glass they do not want. Usually large heavy plates. Flea markets often have stacks of broken table glass they have leaned up to a wall for safety's sake. Hard to dispose of it. Another place is the glass cutters, they have boo boos that they throw away, not to mention edge trimmings. Peek over a glass company's dumpster sometime and you will see what I mean.

Not only does Jimmy crack coral, but he cracks and quenches glass table tops, too. Looking forward to seeing these tumbled, jamesp. Will you tumble 'em in your vibe?

Guessing that rolling 'em means you remove the sharp edges on a grinding wheel, jamesp?

The puree marbles were the prettiest when fried, to my way of thinking. pure- ie rhyming with fury. Pure color, not a cats eye or a swirl). Pardon me Jamesp while I hijack your thread

In the rotary for 24 hours with out grit to remove dangerous edges. Then empty and wash the wicked little splinters away. Even after a few hours the sharp edges are gone. That table glass cuts so fast once you start grit you got to do a clean out about every 2 days. Or grind them manually if you want, at least it will not cut you after a 24 hour tumble.

jamesp what are you going to do with all that marvelous glass after it is tumbled? I put small pieces of rocks and shells in flower pots so the soil won't evaporate so quickly. Looks nice, too.

To bad its so darn expensive to ship by weight. I could give you this stuff by the barrel load each month, on approx how much we toss out each week to month.

I know a few people who have made their small glass chunks by tossing hot water on a car windshield or back window on frozen mornings. No intention to tumble the glass.

Old Tv screens and monitors are a good source of nice thick glass. I have seen a fair bit of it faceted at the club, I personally can't see the point in spending a lot of hours faceting a piece of glass though. If you are going to try a bit of TV glass, (its very good quality glass) there is a bit of a nack in getting it. Health and safety first, wear goggles, cover the picture tube with an old sheet or blanket and do it on a sheet of plastic so splinters of glass aren't laying in wait in the grass for the warmer weather when your footware is less robust. (fancy words for bare feet), then gently knock the tiny pointy little bit of glass on the narrow end with a long rod or shovel and break it off, you should hear a hiss as air rushes into the vacuum inside the tube, when this is done you can then smash up the picture tube without any fear of an implosion spraying glass everywhere. Yes its an implosion not an explosion but it can still spray glass all over the place if not done carefully.
