Is sand anygood for grit? or at least to help with the tumbling. Sea glass and other river and bay stones dont have 120 rolling around to make them round.
Even if it takes a few decades to get them that way

I seem to recall someone on the board mentioning that they'd tried it. Can't recall what their result was and, of course, I didn't bother to bookmark the thread. I suspect that your success with it would depend somewhat on whether the stone you're tumbling is softer than the sand. If so, it might work "acceptably".

I met a guy this summer that's a fellow rock-hound and he says he uses sandblasting media instead of silica grit? I have not seen his rocks but I could tell he was no amateur like me. He was an older guy who drove around on a golf cart, with attached buckets, tolls and everything else one would for rock hunting. He was a treat to chat with and a wealth of info. Where he lives, south of Hibbing, MN is some of the best rock hunting,(Lake Superior Agate, Jasper, and many colors of quartz I've seen, and was open to the public? This could never last?? I got off the sand subject but he said he buys the sand locally and strains it himself. I'll contact him for more details.

I've used Black Diamond sand blasting media in the past with some success. Silicon carbide is still better. Quartz sand will work, but takes a long time and several changes of grit.

I believe beach sand is composed mainly of quartz and I think it will tumble glass fairly well if the glass is on the small side without any angular pieces. It will take longer then using silicone carbide though. The thing with using beach sand is to get it clean first if it's self collected at the shore.Sand dug out of the ground will have a lot more dirt in it so it will take more washing to get it clean.

If you have hard water, mixing sand in with the media helps to get the tumbling going.

Before I run my 60/90 phase with my BIFS, I run an 8 day tumble with clean sand. Helps break off the flakes and usually reveals any main faults I'll see when it's too late. Also does a great job cleaning the nasties off before 60/90.

check out industrial supply inc they have all types of grits. It's for sand blasting mostly, but also you may find what you need for us rock hounds.
