Snowflake Obsidian

[Hunts with stone]

Anyone worked this stuff? I have a slab and can't get a good flake.

A friend of mine that sells rock told me that at the flake in the stone it wants to stop the flake I was told it is ash in the stone.

I have worked it a few times with success, but you can't think of it like high quality rock. Platforms need to be thicker and build up more pressure. Also depends how many ash pockets are in the stone.

I am not at work so I can't post a pic of a snowflake point.  The flakes are not "ash" pockets they are cristobalite crystals and causes some geologists to believe that this is some of the oldest obsidian due to the crystal formation.  It will knap but the crystals are hard and definitely require better platforms. I will post a pic when I got back to work. It will be a bit though. There is obsidian that does get ash/pumice pockets in it and that stuff is only good for rock gardens.

Thanks for that info. Everyone said it's ash, thats some good info.

Well i gave it a go. Tried many ways this one piece just don't knapp. It's like old dry road tar. If it had more glass apeal it would knapp. I'm shure there is better snowflake out there. Thanks for all the input.
