Knapping in Texas

<< < (15/17) > >>

le0n:
^^ yep.

i took a photo because i knew i was going to break it.

then i took a few more photos to show how far i got before i broke it.

i'll probably snap it while notching, hah hah.

le0n:
i've had the heat on this since yesterday evening, so 21 hours so far.



it should still be warm well into tomorrow afternoon.

so maybe i can retrieve the rocks on tomorrow evening after work.

i laid down sand (.5 cubic foot) in the fire pit until it was almost level with the top (layering my flakes and spalls within); then built the fire on top.



the metal bottom of the fire pit has been reading around 250°F for about 19 hours now, so i'm guessing the sand is at least 400°F; being that the top layer of hot coals is over 800°F.

hopefully this works because i put about $2 worth of Colorado (River) Bull rocks in there, hah hah.

le0n:
they were cooled already and i dug them up.

check out what the sand sounded like when i removed the ashes:

Josh B:
I've really enjoyed following along on your thread.  That bull rock looks to be exactly the same stuff I've been picking up in Houston.  I'm going to have to try your indirect percussion method.  Thanks for sharing it.  Josh

JackCrafty:
Any form of indirect in instantly addictive.  Make sure you have insurance that covers rehab...   >:D
