Da bigger, Da better. That is some fine looking obsidian. I know you'll make jaw droppers out of them babies.

Great variety that I have no doubt will end up polished and pretty. Tumbleholic. I want your energy. Maybe just a little bit of your energy would have me jumping over the moon. If a cow can do it I can do it. Jim

If a cow can do it I can do it. Jim I am thinking you wrote the book on spry Jim. Climbing those 8000 foot hills in Wyomingville. And being a bit of a tumbler yourself. Easier to tumble rocks. I do like to work smart, to the point of being lazy.

Looking fantastic so far. Easy to grind, tricky to polish. I will soon have 10 pounds that need a better polish and this 20 pounds that will need a polish LOL. What to do at polish Toad ?

Haven't tried the obsidian yet. Lots of filler and lots of polish for cushioning would be my only advice.

Maybe I'll try it next year though. I have a hundred pounds of the stuff collecting dust right now...

James, in your last post with pictures, the 2nd to last picture (above the large glass pieces) what type of obsidian is it at the top out towards the tip of your index finger. Some kinda mahogany, but is there a specific name? Thanks

Some kinda mahogany, but is there a specific name? Thanks Jean got all that obsidian from an old estate captbob. And I know nothing about obsidian. Jean may know. That came out of a chunk about the size of a brick. There is another small piece just above it in the next photo. It was glassy and hole/fracture free, el primo stuff. Nice to have 50 pounds of it.

Sorry, I don't know the name of half that stuff. There's so many flavors! That's always the problem when getting rocks from estate sales. I Googled "types of obsidian" and checked the images. There was one called "double flow" that looked somewhat close. So I Googled that, clicked on an image and located this web site link. captbob , take a look and see if it is there. You will be overwhelmed by the variety! Good luck with that.

Good info Jean. I was curious too. There is a bunch of crazy obsidians out there. This batch kinda dazzles me. But have to enjoy it whilst wet since I have trouble shinning it LOL.
That 'double flow' is awesome looking stuff.
The black with grey stripes seems to chip real easy. It was easier to slice on the tile saw. Frosts easiest too. The plain mahogany seems to be the hardest. Or most dense.
The one that has a purple martian's eye inside it is about freaky when held at the correct angle. Looks possessed.
