- I did this quite a while ago, and I still haven't finished the piece but I'm going to start posting the videos anyways. Hopefully it will give me the motivation to finish it up and somehow auction it off. I haven't had much time for knapping lately, my plants and work have been taking up all my time! Going to take advantage of the nice summer weather and get back into it soon though.
Thanks for watching. Cheers.

Nice job. Terry
Thanks Terry!
Impressive. This is a skill i want to work on
Thanks very much. Just grab some rocks and start hitting them together, it takes a while to get things going
Wow! Very impressive biface reduction. You are able to remove very thin flakes (and long,too) across that spall with a large hammer stone. Seems to me the keys were lot's of grinding, good choice of where you prepared platforms, super accurate strikes right on the edge of the platform and lots of support/ pressure from your holding hand. Lovely work!
Thanks very much Dooley. Sorry it took me a while to see your comments. Your observations are spot on. After 10 years of knapping I've learned that well prepared isolated platforms are a must for good biface thinning. The amount of preparation needed for that platform will differ depending on the materials used and quality of the rock. For me, soft hammerstones like sandstone work really well for obsidian and other fine grained volcanics like daysite, and grip onto those edges almost as well as antler. Every piece is different and requires a slightly different approach, which is part of the reason why I love it so much! Cheers.
Dacite is my nemesis! I got one small point out of 20lbs of rock. I got several bi faces close to being finished and broke them all. Very fragile stuff
Yes very fragile, brittle stuff, gotta be extra careful!
LOL! My geologist friends always cringe when I tell them I'm knapping dacite! Or browns bench "obsidian".
Do they refer to all of it as obsidian?
@@j.shorter4716 No. Geologist "dacite" is actually a nasty hard, completely un-knappable volcanic rock. But as was mentioned in this video, "dacite" as knappers colloquially call a kind of grainy obsidian, is originally called that because of a location named "dacite" that this type of obsidian was coming from. You'll freak a geologist or calling an obsidian "dacite", real quick! Browns Bench "obsidian" is not an obsidian at all. It's actually what a geologist would call an ignimbrite, which is a volcanic tuff that piled up hot and likely deep, compressing and "welding" it into a glassy material, but it's not necessarily silica like true obsidian. Archaeologists seem to have originally called it "obsidian", but I've seen papers starting in the late 70's start to call it, "welded Tuff", which is far more accurate and palatable by the geologists. Archaeologists are also using a category nowadays called "Fine Grained Volcanic" (fgv) that is not a geologist term, but does kinds of encompass things like welded tuff, basalts, etc.
Interesting, I've never heard the term Brown's Bench obsidian before, is that a more local term? The rock sellers I buy from just call it dacite obsidian, or Daysite (after Day Site, which was the original outcrop it came from I believe). I have seen the term FGV, there are some cool maps I've seen outlining the distribution of obsidian and obsidian-like materials throughout the US and west coast Canada. Thanks for the info Chuck.
@@prehistoricliving Yeah, check the obsidian maps and you'll see browns bench "obsidian" feature heavily in Idaho and Nevada, with a little in Utah. It's scattered all along the southern rim of the snake river plain - which was formerly the Yellowstone hotspot as the continent drifted over it. So it's technically an ancient Yellowstone tuff it's made from. It's one of the few welded tuff types I know of that were used heavily.
As for dacite, simply look it up on Wikipedia and read a few words. You'll immediately understand how un-knappable real geologist "dacite" is. Meh. I don't personally care if knappers call grainy obsidian "dacite". But it does trigger the geologists a little-bit when they do. 😁
Thanks again for this info. Ya I've seen some actual dacite in person, definitely would not even try knapping that stuff! For this type of "dacite/daysite" I think welded tuff is an appropriate term for most situations, whether it be in archaeology, geology, or knapping, works for me.
