Obsidian inclusions
JoJoDapyro:
Yep, as soon as I have my camera up. My phone died, i'll dig out the old camera!
Redhand:
I had a few pieces of that obsidian out by Milford when I went to a knap in by Nephi. It had some inclusions in the stone it looked a lot like ash.
JoJoDapyro:
There are ash inclusions as well. More ash than crystals. A guy recently showed me an arrow head he knapped that had one right in the middle. Here is a photo. The glint on the bottom right of the arrow head is the crystal.
This stuff is also from the Milford area.
YosemiteBen:
One more time....
Snow flake Obsidian has cristobalite crystals in its matrix and is presumed to be some of the oldest obsidian around due to the crystal formation.
Obsidian with other inclusions is usually pumice in nature and will not carry flakes very well at all.
I have a snow flake point I made from a small slab - I will try to het a pic of it later since my office lights burned out yesterday afternoon.
JoJoDapyro:
This flakes well. It isn't snowflake. It is just random inclusions. No rhyme or reason for where, or how big. This stuff is also not black, it is more gray to purple.
