012 Weird Nodule of Black Butter (Dacite) Obsidian Knife - Direct Percussion Biface Flint Knapping
HTML-код
- Опубликовано: 3 авг 2024
- After looking at the weird shape of this obsidian nodule, I decided to record the flintknapping process because I knew it would be a fun one to knap. This opaque obsidian appears to be what is commonly known as "black butter" or informally as dacite although I've never been fortunate enough to work with dacite of this quality. Most dacite I've worked is much more coarse-grained and prone to hinge fractures. This nodule is the only one of this type that I picked up from Glass Buttes and I wish I had more as it really feels like knapping butter. Thankfully, I was able to produce plenty of good flakes for smaller points during the bifacing process shown in this video.
Technique: Direct percussion with a copper bopper.
Material: Opaque black obsidian from Glass Buttes

Please continue making these - fascinating
Thanks. I will continue until supplies last!
You are a knapping machine. Thank you for showing me how you would find your target and the direction from which to attack it and how you set up beautiful platforms and almost always executing with perfect precision. I've seen many videos and your confidence is reassuring and empowering.
Thank you, I’m glad you enjoyed watching! ✌️
There is no way I thought you were going to get that big bulbous backend off without losing that thin front end. Especially with a crack there! Well done.
That was exactly my thought when I grabbed this nodule. The obsidian gods were on my side that day 😉
@@knaptime all except for that overshot at the end there. But dacite is like that sometimes. I've sworn off dacite as it does not like me lol. But good job on that weird shaped rock.
Thank you!
I love the color of this material. It's deep and dark matte black appearance is so consistent that it almost looked like plastic on the first few flakes you removed. You guys are causing me some severe stone envy over here.
That “don’t try this at home” line made me chuckle. ;) Excellent job, beautiful work!
Thank you very much!
Well done, again!
Thank you sir!
Very nicely done. If you have access to Glass Buttes, there lots of that material to be had. Glad I found your channel & look forward to following along. Thanks for sharing.
Tricky piece but you mastered it.
Thanks, I got lucky!
Great job!
Obsidian is a lot like glass... too hard, & it shatters!
Too soft, & it crumbles. Your platforms were set just the right ! Perfect angles😇
Sounds like you’ve done some knapping yourself! Thank you for watching. ✌️
I too am addicted to obsidian.. I hope I never get better lol. Nice work.
Thank you!
😙👍
I would love to get that very same kind of black butter obsidian. Hopefully you could me some info on where to get some.
It was pure luck that I found this piece. Someone must have left it behind in an area where I was collecting another variety. I can tell you that it came from Glass Buttes in Oregon but don’t know the specific source of this obsidian type. Maybe someone can give you more details about where exactly you can find it at Glass Buttes.
Hey man where do you get the large pieces like that? I'm very interested in using them keep doing the good work you are awesome!
Thank you! See the reply to your other comment about the material.
You were probably an A student in math and physics.
Haha only when the answers were on the back of the book 😉
@@knaptime 🤣
@@knaptime This actually happened to me in my High School Algebra 1 class. The school had gotten some new books between my freshman/sophomore year, and when we received the books at the beginning of the school year, I was mistakenly given a teacher's edition. I kept it quiet for as long as I could, but I was eventually discovered when it was noticed that I was phenomenal at the work/homework, but couldn't pass a test to save my ass.

Very interesting to watch. What are you doing when you rub the other stone on the edges?
Thanks for watching! Grinding the obsidian edge with the other rock is called abrading. It helps remove the sharpness of the edge so that it doesn’t crush when I hit it. If I don’t abrade then the flakes won’t travel far.
Do you have any trouble getting the black obsidian I live close to a seam of it that goes all along a gas well road for a couple hundred yards it looks like a seam of coal but I found out it's not its about a hundred times as hard I hit it with a hammer and didn't eaven chip it
Interesting. Obsidian is all over the surface in glass buttes. I just got a limited quantity of this specific type.
Endonde encuentran esa obsidiana o donde la compran
Where do you find that obsidian or where do you buy it?
En una montaña que está como a 4 horas de donde vivo en Oregon.
Knapp some churt or flint and make a video
I’ll have to get some chert first 😊
I never understand , you start with a stone big as a football and end up with an arrowhead. I could have made a grand worth of jewelry
I can see how these videos lead you to think that. In reality, a large portion of the flakes removed during the process are further knapped into smaller arrowheads or eccentric pieces.
It might have been a unipolar blade core if you did not work on it before. So it seems that you destroyed an archaeological artifact!
Things aren’t always what they seem 😉
