Great job man! This white lime is used here in southern Spain as a paint for the walls and tree trunks. Paint your house's walls with it and not only they will be preserved longer, but it will also fight funghi, moss, parasites and heat accumulation. White lime painted walls and tile covered floor is a classic formula for a cleaner, fresher and more beautiful house

For some reason I want this dude to live forever so he can get to the point of modern technology

The lime stone is also a good additive to iron furnace, when the stone is heated and turning to white qick lime, carbon monoxide (CO) is released, it helps stripping oxigen content of ironoxide, same method is being used in modern blast furnace process, mix some lime stone pebble into your baked iron ore nextime , hope to see the good result!! :)

I feel so dumb. He keeps breaking rocks and showing me the inside like I am supposed to know what he is showing me, and I am like "yup, that's a rock alright" :P

I'm pretty sure that is just "Non-hydraulic Lime Mortar". The Ancient Egyptians were the first to use lime mortars About 6, 000 years ago, but they have been used all over the world including to face the huge pyramids made in central America. Actual Roman Concrete is based on Pozzolana, volcanic ash and the chemistry is very different (it has additional aluminosilicates and forms a geopolymer), in fact it will set under water whereas non-hydraulic lime mortar needs to slowly absorb CO2 from the atmosphere so that it can return to a limestone like state, but with the incorporation of the sand and or rock aggregate.

You should keep adding captions to you videos there really helpful to know what’s going on

This man has so much talent that I am in awe. Story teller, script writer, actor, cameraman, editor, producer and talented and knowledgeable student of primitive skills. I wonder if he earned some kind of film making degree at a university.
And I like that this guy shows what a normal man with a normal body can do. I don't prefer some muscle bound guy who clearly spends more time working out at the gym trying to look like Tarzan and eating stuff you wouldn't touch short of actual starvation than he spends in the wilderness. Primitive Skills is the guy who actually has it going on.

Imagine being a tourist from a big city, getting lost in the rainforest for a month. Days go by, you're unable to catch food, youre cold, hungry and sick from eating the wrong berries and drinking dirty water. Then you stumble across this guy in his little paradise.

I love this channel. Literally when I think of what makes youtube great this channel comes to mind first!

[Stahlengel]

My kids and I are glad you're back, they love your videos, though I have to stop them cutting down small trees to try and build what they see. Excellent work as always.

This kind of content separates you with other "Primitive" videos and places you up with the original "Primitive Technology." You actually teach people and not just make pools.

In case anyone cares: It's been recently (about a year ago, so 2 years after the release of this video) determined that hot-mixing the limestone is essential. You don't want all of it to react, you want some to still be reactive (that is to say still capable of reacting).
That way, it is currently presumed, the wear that happens in the stonework naturally happens through places in the stone that haven't reacted yet, because they are more brittle than the surrounding material.
This in turn can "heal" and reinforce that very area, once water drips into the crack.

As far as we know that's why ancient roman buldings are still standing while modern concrete breaks down surprisingly quickly, in comparison.

Tip: to make it faster, use pistons and a bit of redstone, so you can spam right click and it will be much easier

You should make a spinning grind stone for your tools now that you can make concrete

I love watching this man work at what he knows what he is making.

[loveofiber]

Hasn't anyone noticed that he has harvested his rice??!! I was wondering what was his yield. Also, he planted wild spinach at the end of the second tier just above the fish pond. And, lastly, one of the seed species he foraged was mustard, I didn't notice that he ever planted it. He has a steep learning curve for these videos, I am surprised he gets them out as often as he does. I am a retired teacher and I have used one or two of his videos as teaching tools.

Now imagine doing this but for the whole fricking Rome, like the coliseum and such. Crazy times for real
