Awesome, did not think of that.

The lighting stone I tumbled was finished in the Lot-O vibratory tumbler. I used a rotary tumbler for the rough stage, and did the last 3 stages (SiC 220, AO 500, and AO polish) in the Lot-O. It got pretty shiny, almost as shiny as a Lake Superior Agate. I think the big difference between my lighting stone and yours is that mine is from Lake Superior, and the brown part is probably a lot harder than it is on yours. Mine is basically brown jasper with a few quartz lightening bolts running through it. I believe that the lake Michigan lightning stones are considerably softer and probably will not tumbled to a high shine. Rob ( Jugglerguy) would be my go-to expert for all things Michigan rocks... Maybe he can chime in.

The light color is sometimes banded agate. Those would be much harder than Lake Michigan thunder eggs.

The bottom line is whatever I've got from Superior (probably rhyolite) is a completely different rock than the Lake Michigan lightning stones that Son Of Beach is trying to tumble. And that is why mine got shiny, and his did not.

I love the Moroccan septarian. It takes a great polish on the wheels.

It's good to know the thunder eggs tumble, I have a handful I've been holding off on not knowing what to expect.

Son Of Beach, that looks great! I like the look of shiny glass.

Chad, those are really cool looking stones! I love the pictures you took too...especially those last couple! I think I might try this setup now that I'm starting to accumulate more finished rocks. I can kind of play with the background a little. This lens that I use makes it tricky to hit the sweet spot on the rock that I want in focus. I wish I had a way to see it on a bigger screen in real time. I tried a thing called "tethering", downloaded some software and all that. When I went to plug my camera in to try it out live, the charging cable got way too hot, something went wrong. Not sure why it would pull more power...a little out of my technology threshold.

Are those Leland glass? They're beautiful whatever they are! This type of slag can be found all around TN and KY near the old blast furnaces of the civil war. I think lots of folks on eBay and such are freely collecting it and then selling it as the Michigan Leland Blue

Those have got some cool colors for sure. The one on the far right in your first photo is my favorite.
I like the last photo with the narrow plane of focus. It gives the photo a dreamy quality.

Would anyone be interested in cabbing or tumbling slag glass? I have found plenty this year in the few rockhounds I've done and have more than my fair share. The handful near the quarter are a few with more potential IMO.
I guess if you are interested let me know, we can work something out. Not really a sale per se, I just have more than I care to keep on hand and I'm sure I'll find more
I don't know if it's big enough to cab and this is for sure a man made and likely material you'll want to use some kind of mask with, it has an odor and is more gaseous than normal when I crack the lid after a week of tumbling.

That slag glass looks super cool! I always see people being disappointed with finding slag glass, but I would be elated. It really does have great patterns and color in it. So, you found it waaaay south of Leland, but still found in Michigan... maybe in the mitten? Have you rolled this yet or did you find it rounded like that (both the septarian/lightning and slag)? Look up smelters from the civil war. That blue, green, purple, gray slag can be found all over the South. KY, TN, AL, GA, etc. There's even a map online of all the smelters in TN and all you have to do is visit one that was operational (some were destroyed by the Union before operations could start) and look around in the creek areas. Stuff is usually everywhere. I trashed prob a good 50lbs years ago because nobody seemed interested in it then like they do now.

brybry I may have to try that. I haven't really done a "soft" rock tumble yet so I have some trial and error ahead of me. The corn cob you just run dry, correct? Son Of BeachI got some crushed corn cob at a store like Cabelas that carries ammo reload supplies. I watched a video on YouTube where the lady followed the recommendations of Shawn at The Rock Shed for tumbling soft stones and got a great shine on pink calcite. I put my orchid calcite back in to see if I could coax more of a shine onto it. She took her 3# barrel filled it to the 2/3 to 3/4 level with dry corn cob, weighed it, 2Tbsp of polish for each pound of corn cob, fill the barrel almost to capacity then push your rocks in. Cover and tumble. Mine have been tumbling 2 weeks without peeking. Figured my polish barrel will not be in use for a couple more weeks so I'm just going to let them tumble. Maybe open it up and put another scoop of polish in unless the experts do feel it necessary

I only have this small supply of septarians for now anyway

I could bring it with the flint.

But for real, you don't have to come all this way just for a delivery
