bjrogg:
Don't even mind it cooling down a bit but the days are getting shorter. Still dark at 6:00am and suns gone by 8:00 pm.

Zuma:
BJ just remember that the deer will be coming out to the grass sooner :D
Here is a link that has a bit about that tough obsidian.

        Green Obsidian knife

Zuma:
Every thing turned out great, Dacite too. :)
Actual time six hours. :) :KN The Mexican obsidian, I think needs only 400 degrees. (=)
It abrades well and the flakes are smooth but there is a tendency to lop to easily. :-K

Zuma:
It took kid gloves to coax this one out of the Mexican Green. O:)
It started as a 1.5" thick brick :-K
Zuma

bjrogg:
That's a sweet point there Zuma. Doesn't look like a brick anymore.
