If you are working with Davis Creek material and you have a single color you can cut an eye effect. Cut parallel to the color band, look closely and you will see a "fibrous" pattern with the "fibers" all going the same way (sorta like tigereye). Cut the slab 1/2" thick to get a good density, orient the "fibers" perpendicular to the long direction of the cab, cut a long, slender cab with a high dome and you will have an eye that rolls across the cab. Here is a bracelet that I made with these eye cabs. The eye doesn't show as well as I would like (I'm still learning about special effects in my photos). I've been collecting and working Obsidian for the past 30+ years and Davis Creek is my favorite.

Excellent Bob,
I have only cut a small amount of Davis Obsidian. I can see the eye effect in your photo, Have you cut much Glass Buttes Obsidian? If so, what differences do you see. I have cut TONS of Glass Buttes, but very little Davis. Thanks for the good info,
KOR
Dan

Thanks for the instructions.

I'd be interested in advice on orienting other rock, just got a saw about 4 months ago. I think I cut some bronzite in the wrong direction, not sure.

Ok, that half inch idea is good. You will have time to straighten it out a bit before it gets too thin. I will try that. With the fiber. I have a hard time seeing the lines. I think it is dain bramage but it might be my glasses.
