Heat treating Buffalo River

(1/2) > >>

leapingbare:
  So i tyred to heat treat some buffalo River chert last night and this morning when i looked at it there was no change in texture, only a change in color went from a dull light brown color to a Rusty color brown.
 I cooked it in a pan of sand in the oven at 550' for one and a half hrs. The Kansas chert i heat treat changed and became waxier. But its the buffalo river that i would like to get waxier.
 Anyone ever had any success heat treating Buffalo River?

david w.:
i have never heat treated and i can hardly knap but 1 1/2 hours seems way to short

leapingbare:
it was in the oven about 7 hrs, tuck 5 hrs to get the temp up to 550

david w.:
oh well i never heat treated so i really cant help

El Destructo:
Jesse .....I cant find a Thing on Buffalo River....but I did find this....in case it may be helpful in the Future....why do you want to Heat Treat it anysways??? Everything I have read says that it flakes great without Heat....is it for the Color Change???
