Me too!
I'd gladly pay you Tuesday for some obsidian today :)

And I'd certainly pay shipping!

Yes Sir!

I'm trying to figure out how to work obsidian as well... :)

Reading back through a search on Obsidian last night I'm guessing I should start with Glass as there's no Obsidian to be found around Houston.

Lee, I only know how to knapp slabs, I don't know how to use spauls. Having said that, I don't have access to a saw any more. 

Send me a PM if you want some. Im sure we can work something out.

snowflake can be knapped but it's a bear as the snowflakes tend to be hard, the ol' boy that owns the rock shop here made a real nice point out of some but did say that he didn't like working with it, Bub

I guess it depends on how big the ash "snowflake" is. I have seen it knapped, but only when it has very little ash. I have tried some with a moderate amount of ash and it stacks when it hits the ash leaving you with a great big ridge. The ash is usually soft like trying to knapp around cortex or cracks in the rock. No matter how hard you try you cannot get a flake to travel through a crack to the other side. At least I can't, but I already told you Im not a real knapper.

Great responses. Justin and Eddie, I'm gonna have to go check and see what I got that you might want or need, but would like to try pressure flaking some of those mini slabs. I'll pm you guys later after I check my available resources.

Thanks Tracy

Is it big enough to slab some cobles?

You can cut about 2" with a 4" blade, a little more if you take the safety features off. You can also look for a cheap 10" brick saw. I use my 4" for cutting triangle slabs.

Do you need to lube the cuts? Oil or Water?

you can get a little eight inch tile saw from home depot, i got one for 'bout $70.00 like mullet said you can make about a two inch cut, wide enough for a blade, just fill the tray with agua, and if ya buy mook slabs you can cut shapes, heck i've cut triangles out of slabs of brazillian agate, Bub

It depends on what stone you are cutting. Water is fine for obsidian and a few others, but oil is needed for a lot. The oil actually keeps the blade clean, keeping mineral buildup off the cutting edge.
