Just imagine the neighbors going "Dammit! Honey the neighbors being a caveman again"

I love the fact that Andy shows all of his failures. It makes it clear that this kind of technological advance is difficult.

"FISH?" When sieging a castle you want to bring a herd of pigs with you. When sapping the walls you add the pigs to the fire which raises the temperature high enough to make the earth above become brittle and collapse the wall above it. Dried oily fish have been used as a fuel by many people and continued into relatively recent times in the form of a ferry that once crossed Lake Michigan fueled by dried sturgeon. Maybe the original artist is suggesting that oily fish will help bring a high stable heat.

Soooo everything you are doing has been a HUGE part of my art practice. History, anthropology, materials science, applied vs. Theoretical science. Experimentation. I have worked in just about every facet of the arts and commercial/industrial fields in pursuit of this same goal. I LOVE WHAT YOU ARE DOING. I would LOVE to contribute any experience or knowledge I have developed to help you you out.

I couldn't tell for sure, did you add straw to your clay when making bricks? That's important. Some kind of fibrous plant material, such as straw, grass, etc, it adds a lot of strength to the bricks.

Thank you for showing how hard and tedious it was to live before modern tech Your dedication to hands on trying out your explorations is TRULY AMAZING admirable

Once again, the HTME team has put an insane amount of work for one video! The love you guys have for this stuff is infectious haha

The bricks need a lot of work it seems. As other people have mentioned they probably could use less water to reduce deformation. A tip I saw on primative technology was to use wood ash with water on the brick mold to allow it to slide out more easily, but also being dryer would allow it to slip out more easily too (also using wood ash on the floor to prevent it from sticking). I believe the design of your kiln was also pretty flawed, if you're using rectangular bricks you should be building a square kiln (make sure to make square bricks too for end pieces). If you need to make a cylindrical shaped kiln you should be using trapezoidal bricks, where the interior angles are 75 and 105 degrees respectively (for a 12 sided circle). One more thing you missed is the critical step of firing the bricks (you can test to see if they're fired by putting them in water to see if they dissolve, if they dissolve then they weren't properly fired). When you put them around the fireplace all that did was dry them, which isn't bad but it doesn't make them fired; they should glow orange/red or be close to glowing. I've never made bricks in my life so feel free to disregard all of what i said, but there's lots of videos about how to do this stuff on youtube (e.g. primative technology)

I wonder how long until he makes a fuse lock musket. He has almost all the materials he needs, besides potassium nitrate I think

10:20 The clay was actually way too wet for making bricks, it should be a lot drier and harder, somewhat like the consistency of hard dough. The clay being too wet could be harder to handle, and more importantly it will shrink significantly and unevenly when drying, causing the brick to have inconsistent shapes or even cracks.

She worked with cement, made bricks AND still has great nails!! RESPECT!!

Despite being lower-tech, wooden molds generally make for smoother, more consistent bricks. Great video

Omg, it’s a rare specimen of the Iron Age infrared thermometer!

This should be titled “different ways to fail at making glass”

Glass flutes were discovered in egypt and other desert regions whenever lighting pierced through the sands. Glass has always been around. I imagine someone collecting a glass flute after lighting striking the ground. Their minds must have made the connection between heat and sand producing glass.

Shoutout to Annalise :) first her and now Lauren doing all the grunt work, they da real MVPs

Try watching the OG PRIMITIVE TECHNOLOGY to make better bricks and kiln/oven

I really love the reset of this channel, I think y'all are getting so much better at craftsmanship.
