Thanks Walt. They were never re-melted, left as is from the glass blower making color and patterns vivid.

This is afternoon sun passing thru west facing windows. Tumbles are scraps from a glass blower. Hand held 2015 iPad Pro. Pure sunlight, no artificial added. Background paper dead white. THe gridded window pane reflection is classic

I just melt mine into bricks cut them into cubes and tumble them Your glass has more color then the COE 33 glass dose I have yet to tumble 33. It is harder than soda-lime 90 and 96 and guessing it should polish easier. if re-melting the blower's glass goes about 1/2 Mohs softer for some reason.

THe gridded window pane reflection is classic I'm about ready to see some Oregon window pane reflections from a Sonic. Or do you guys ever get sun ? do you have two 4 pound or one 12 pound or 14 pound hoppers.

I'm about ready to see some Oregon window pane reflections from a Sonic. Or do you guys ever get sun ? do you have two 4 pound or one 12 pound or 14 pound hoppers. Cloudy, rainy here, artificial light. Two 4lb hoppers, Ran one load with random stuff, and endcuts/ceramics. Sorta followed the loto recipe. Different action, that's for sure. I can also see why you need production roughing to keep it fed....
Motor bearings *might* have sounded a bit different after a week, want to open it and double check the bearings again. Thinking of a way to attach a larger flat tupperware and try polishing a thicker larger slab.... Interesting the long thin piece of Tahoma was just fine all week, but I did a final 'burnish' with ivory soap for a couple hrs and that's when it broke, as well as one or two others - I guess the borax might also act as a cushioning agent.... Crappy photos, decent polish though it's not 'reflected' in the pics.

Those came out beautiful! So many different patterns and colors. I think the little blue and white one in the second picture is my favorite. It has an interesting pattern. I have some creek glass I collected to tumble but never thought of trying slag or art glass. Your pictures makes me want to try.

If you find a way to tumble shape/polish it the same recipe will work super for agates/woods/jaspers. It is a fast tumble for me. Makes it pleasant when there is not such a long wait. I blame my success on the use of slurries and gentle tumbling methods.

endcuts backs endcut fronts I would love to go rock hounding with you and find what is in your photos oregon. Is that your first Sonic load ? Do your bearings have grease fittings or are they self lubricated ? The single long 14 pound original Sonic hopper I have will tumble long items like 3 inch diameter limb casts say 9 to 10 inches long. Call it a small log tumbler, it simply rolls in one rotary direction with no end over end movement. If you weld you can easily make hoppers for that beast. I could see a 24 inch long hopper say 8 inches in diameter for tumbling an 80 pound log quite easily.

I would love to go rock hounding with you and find what is in your photos oregon . about 50% I'm the primary finder. Seems like there's one estate sale around here with tons from a collector every so often. A different kind of hounding, But Figure I'm the secondary finder then Is that your first Sonic load ?Do your bearings have grease fittings or are they self lubricated ? Yeah, first experiment. I think it's the motor bearings that changed pitch, Have to investigate, but too many projects, and have to prep some more rough...

Any thoughts on a flatter container to do heftier specimen slabs with lots of smalls/ceramics?

Wow! I never thought about tumbled glass. But these kind of remind me of marbles when I was a kid. The variety is amazing. The tumbles are all perfect with not even a chip or pit in any one of them that I can see. James, you have turned this glass tumbling thing in to something spectacular. Thanks for sharing! [edit] If it were me, I would see how some of this material did inside a small sphere maker. Just to see if I could get marbles out of it. Hehe. Just thinking.

[edit] If it were me, I would see how some of this material did inside a small sphere maker. Just to see if I could get marbles out of it. Hehe. Just thinking. Those started out at about 13 pounds @nevedabill. They got tumbled down to 5 pounds. I used the high speed 6 inch barrels and super coarse SiC 10 which removed most of the 8 pounds from the starting 13 pounds. In 5 days. Ya know how tumbles look great when they stay in step 1 for a long time. If agate they'd had to run 3 months to shape so much ! well, these were brutally reduced in size resulting in the near perfect surfaces. Not a single one was tossed for defects. Plus it is glass and most glass is almost free of cracks and pits. I'd love to have one of those sphere grinders that you can load 2 dozen pieces at a time in. At least people know these are not marbles. And were molested with some other process... Rewarding to have defect free must say.

Plus the old timers often got the best of the best, and the kids auction their find collections for little of nothing. The basic hopper should probably have a round cross section for fluid movement. The vibration generator seems to cater to round hoppers. Never know though, a flatter hopper may get it done too. My guess is the slabs may get trapped in a corner and cause a jam. I will say a short say 10 inch long pipe say 12 inches in diameter would give large slabs a place to rotate and polish. That base unit should have no problem shaking such a sized hopper.

Those multiple sphere grinders are called Ball Mills. Made one and used it mounted in a floor model drill press with a low speed setting. Worked fairly well, higher speeds caused it to sneak out the door of the garage and head off down the driveway towards the street until it got to the end of the drop cord and unplugged itself !

Heard of walking catfish but never a walking ball mill agatemaggot. I have a dear dog named Maggot. video needed of walking ball mill. got photos ? Would be interesting to see your invention. I think I understand the use of the press of the drill press. Can the round groove section be made out wood ? or metal ?

Thanks for the reference amygdule. I remember this home made unit after seeing your link. jm made it look easy. Glass should be a quick grind being soft.
