I put some in a coarse load quite awhile ago but I was useing a homemade barrel and did not see much difference. I am going to start a new batch of agates and have some left over and will throw it in. I got the sand free so will not be out to much. I will be out a little time but, time matters very little to agates as they are so hard. give it a try and let us know what you think I will do the same

I have heard, I have no experience in this, that sandblast medium can be used to tumble. It breaks down faster than conventional tumbling grit however. The article read that the grit was run all the way through to polish with a little added on the way. It was not used as polish however. I guess it makes sense. It will wear itself finer and finer untill it is microscopic. Give it a try. It might be an alternative.

i have some my dad gve me, it looks pretty gnarly and to be honest i haven't had the cohones to try it....but it might work, hey, regular sharp mason's sand would probably work given enough time? it would break down sooner is all?
go for it, Shorty....

Hey Shorty,,, Don't quote me on this but I think sand is comprised of mostly quartz and quartz is the same hardness as what you're trying to tumble. Tom

Hi again shorty,,,,,,, Using sand to tumble rocks will work on softer materials but even then it will take a long time. Nature uses sand to tumble it's rocks and it's taken Her millions of years to just rough them in!! LOL Ya got me thinkin' though. The sand might work fine on making fake sea glass.It won't polish it but I think it will give the real frosted look. That being said,it just might work for roughing obsidian!!It would of course take longer then using silicon carbide but what the heck,,,,,,it's free!! Maybe we should ask "Sands" about it......... He should be an authority on the subject seein's how he's got the same name!! LOL Tom

I am really interested in this. I looked at Black Beauty sand blast grit. I believe it is silicone carbide. It is large and I believe it would break down fast. It would seem to work better in a larger tumbler than a smaller one. I do not know about vibratory.
