I just moved my slag glass from 60/90 to 220. When I opened up the barrel and emptied out, the bottom 2" were cemented in there pretty good. I had to add water and stir it loose with a 1/2" dowel rod to break it loose. Here is my question - is this a common thing when tumbling slag glass? I've never had this problem with any other material. I am suspecting that it is glass particles making the cement/snot in the bottom. I have a 6lb barrel with about 20 pieces of glass and the rest is obsidian that does the same thing. So as an experiment, I stired the contents loose, put it back together, rolled it for 10 minutes to see if the bottom was cemented again. And it was! When I set it down, it only sat long enough for me to remove the 6 nuts. So I am assuming the slurry settles quickly into this cement like state. Sure would like to hear others experience with this! thanks.........gr

You know what Gary, this is probably completely unrelated but.... I did have some glass tumbling in one rotary and agate in the other and noticed when I did a rinse and recharge that I had about 1/4" of cemented gunk in the bottom of both 3lb barrels. What I thought strange was that it had never happened to me either. Then I noticed that Patrick, my husband, had been out tinkering in the garage and without telling me had cut pieces of foam to put under the tumblers to elevate them. He thought the motors felt too hot. What actually happened though was the tumbler became unlevel and caused the cement. When I removed the foam the tumblers behaved normally again.
Yours sounds different but thought I would share my experience anyway just in case.

Thanks Krystee, my shop is lower on the other end but I think I've got my barrels pretty level. I know that when they weren't level, they would walk right off rollers if the stops weren't there

Gary,,, I've only done a few loads of glass.Some was just broken bottles and 1 load was slag glass.I did them a long time ago and do remember having a bit if "cement" at the bottom of the barrels.
It's probably as you say,,,,,tiny,tiny glass particles with the ground down grit??
Not much help here though!

Cool, I wonder if there is a practical use for glass snot.

Gary, I have a tumbler going now, only a 3 lb'er, but I'll be emptying it tomorrow. I'll have a chance to see if I have to same thing in the smaller tumbler. I just love the colors and banding in the slag glass. Can't wait to check it all out. This is the first week in the coarse. How long does it take in the coarse-60/90 grit? Tanya

Steve, could be as a saved slurry. I'm using some of it now in an agate run but, won't know till 6/10/ if it will do the same thing to me or (s)not.
Tanya, I had mine in 60/90 for 15 days in my 12lb rotory and 98% of them were ready to move on. Nice and well rounded.

Gary, I just emptied my 3 lb'er after 6 days and most of them are ready to move on to 200 grit. I am so thrilled with them, the banding and everything is just beautiful. I have to assume that the glass does not take nearly as long as the jaspers, agates, etc. Anyway I did have some build-up on the bottom but mine is 3 lb so not as bad as yours. I will check them again in about 5 days of course burping them every 2 days. So far no gas build up but I do just open it a little every 2 days. I love this stuff. Thanks for aiming me to Stoneviews.

If it were the combination of grit and tiny particles glass particles making the cement/snot in the bottom, Wouldn't it be up on the sides as well? My thought because there is no "bottom" to a rolling tumbler barrel. Just thinking?...Tammy

Tammy, I'm pretty sure that when I stand the barrel up to remove the lid, everything settles to the bottom quickly. Plus the vibration from the other rolling barrels, (4), on the table that everything is on acts as a vibratory settling stuff down before I could get the lid off. Next time I'll set the barrel on a different table and see if anything changes. Thanks for posting in on this!
