I almost made a preform!!
« on: April 18, 2017, 11:22:31 am »
So close!  Coolest obsidian with some weird metallic green flecking look to it when I shifted it in the light.  Totally stoked to have gotten one that close, figured out the angles better this go round to get the thinning flakes to run all the way across the piece.

Progress!

Looks like end shock, might be something else.  Either way don't hit preforms from the end unless you have isolated a platform and support it well.

I wasn't hitting it on an end but I was hitting a spot that i kinda knew was borderline but close to a stack I wanted to remove....I'm happy I had a sense that the hit was bad but unhappy I didn't have enough sense to not hit it.  :o

Don't worry if you had that much sense you wouldn't be hitting rocks anyway.lol.  :o
You'll always be breaking them it's just that they will be nicer ones you break as you get better. ;)

PaulC, you got it going now, great improvement, remember flakes only need to go just past half way from each side to thin not necessary to go coast to coast. Lookin good. Bob

I agree that was a preform. You got close, and your guess as to what went wrong is probably right. Always evaluate the failures.
