Hi friends, I went to town today and found about 1.5 pounds of obsidian at Vinnie's Thrift Shop (75 cents). It's in three pieces, roughly 3" x 5" each, up to 1" thick. Some edges are thin and extremely sharp. I've never tried to polish this glass as I haven't had any rough material. Now with this, and maybe getting more, it may be time to try. It would have to be made into much smaller pieces, and I'm stumped as to how to cut it. Would my trusty little 7" tile cutter likely work. Using a saw seems counter-intuitive. I would expect the material to shatter. Can anyone set me straight on how to get it into smaller bits? Also, would it work to make up a load by adding pieces of ordinary glass? Thanks for your help. Cheers! Robbiejohn.

Cutting it with a saw is a GOOD thing!!!! It's not likly to shatter unless it gets snagged or something. But I really should zip it before I say something that i dont even know about the truth, lol!
You can smash it with a hammer, but with so little amount you have, not a good idea. Smashing Obsidian make lots of tiny shards. But that isn't the way I do it anymore. And I find you can get lot less tiny shards (if any) if you hold the rock, and tap it on a sledg hammer on the ground! Seems like it brakes off larger bits. =)
You're better off tumbling obsidian with obsidian (of the same type). Using glass as a filler may work, but there are too many variables to know. Not all obsidian and not all glass are created the same.
As suggested in another post I tried a small diamond blade on my Dremel a few nights ago and found that it cuts it like butter and no chipping on edges. You get less waste than your tile saw would create. I know I`ll use mine for it again when needed. The blades are pretty inexpensive too for the Dremel.

Overall I agree with Steve--many variables between glass and obsidian. That being said, I just tumbled some glass and obsidian and the variables worked out in my favor--both tumbled and polished nicely. I remember reading that glass can be as low as Mohs 5 in hardness and obsidian is 6-6.5 so it seems that if anything goes wrong it will be with the glass. This is just a *slightly* educated guess, though

wampidy: The verison jet pack works excellent for internet. I get 5 gig for fifty a month but I have not gone over 4 gig yet and I watch a lot of the weather channel videos.

rockpickerforever: A bath tub, that's funny Jim! I have just a shower, but it ends up being extra closet space. Comes in handy for storing all those goodies bought in Quartzsite!

wampidy: If I keep this trailer I am going to take out the tub and make a cabinet out of half of the space. If I need to soak my feet (or head) I have a plastic tub for that.

drocknut: Jim, I am currently using something called fox fi through my phone for internet. Thought about getting the jet pack but going to try this with my current data plan before I shell out more money. Generator is top of the list right now.

rockpickerforever: mr.mohs, how did that hose clap work?? Are you up and grinding?? Sending some cooler weather (maybe rain?) your way for the weekend. At least the Heart concert is indoors Sunday. We have a lot of outdoor concerts here... mohstly. Rain sucks then.

rockpickerforever: Made chili relleno casserole today, yum! Also started Jalapeno jelly (jals cut-up and steeped), but will have to finish the job tomorrow. TIP: Take a leak first, then don vinyl gloves. Sometimes I get the oils in my eye anyway, but not today!

mr.mohs: gritz--never had that error & I've had many---pretty sure you'll figure it out- are you posting pictures from photobucket?

mr.mohs: what kind of chili did you use, Jean? what did you make the casserole out of?
Apr 23, 2014 22:28:37 GMT -5
rockpickerforever: Ortega green chilis, mr.mohs. With jack and cheddar cheese and covered with El Pato hot tomato sauce. It's the casserole I brought to the BBQ in Quartzsite. Do you remember? Did you get some of it, Ed? It is so good!
