Heat treating Buffalo River

<< < (2/2)

  Jesse, when I heat treat the local chert we have here. I just put the spalls in the toaster oven, turn it all the way on (500dgs) and let it cook all night. I unplug it in the morning when I go to work and it is cool when I get home. You can usually hear the diferrence when you smack it.

The Buffalo River chert i heated last weekend did change some, it napped better and was less grainy.
 Thanks for the list Michael thats a good reference, not only for me but for anyone.
