Nice job, obsidian is a bugger to get all the scratches out of - you did a great job! Those rainbow obsidians are amazing - the play of color is beautiful - if you can cut it right
got any tips for cutting them right?

Hey Thanks everyone.
Hi tweetiepy,
I cut that slab or rainbow pretty much right on the flow lines, (the line that have the tiny air bubbles, that refract the light to make the colors), you should be able to see fine layer type lines, I cut as parrallel to those lines as I could, and as you dome it, you expose the other rainbow lines. In the picture the highest part of the dome is right below the flash, the darker area, and as the dome goes down it shows different colors. If you cut the slab slightly off parrallel to the lines, you end up with the rainbow sort of spread across the slab, doming doesn't change that too much. But as most rocks, each piece is different, so there is luck involved to :-).
KOR,
Dan

I keep coming back to look at the 1rst one. The shape and doming have that natural ballanced look. Good work.

Hi All, Thanks!!!! Obsidian can be a bit harder to polish than say agate, you would think a softer stone would polish quicker, but I've noticed on the polish wheel it can take at least 3 times longer to polish. The scratches can be troublesom. but the way I get thru it is to totally dry the cab off and inspect it before moving to the next grit, the water can hide minor flaws that show up during polish. Believe me I know :-) But dry off and check before moving to next grit. Also when polishing, let the polish wheel dry out a little and let it get a little warm, notice I said "LITTLE". The heat, or warmth helps bring the polish out a bit quicker, but you can scratch it if it gets too hot. Right when the polish STARTS to dry out, is about the best. I stand there with a spray bottle, and add about a 1/4 squirt of water at a time. Keep polishing, and it will come around if the other grits were done properly. KOR TTYS Dan www.dbrockwerks.com |
