It's foolish to attribute knowledge of stonemasonry to freemasonry. Monks had access to books like Vitruvius' "De Architectura." It wasn't a secret.
He is at Hadrian’s wall and he is looking at a simple house
I didn’t know much about limestone just where it’s most likely found but it took me 2 minutes to realize one can melt it and it would react with water creating a usable material that will become solid afterwards. Before even watching this video. I knew this right away Cuz I’m into chemistry. If I am being honest it’s not that difficult to figure out. lime stone will bubble with lime or vinegar cause of the calcium. which means water will form it together once again after melting it. Just like how water was what created it too.
"A kind of alchemy..." LOL do you mean chemistry? 🤣🤣🤣
It was all called Alchemy at the time....
But how did they make the bricks for the kiln before they made they kiln?😯🤔🤔
Aliens gave them the first couple bricks duh
Haha. That blows the chicken/egg question out of the water for sure lol
@@peeb8301 😂🤣😂
a kiln doesnt have to be built upon bricks.. you can make it directly from clay
@@alwanrosyidi2772 ahhh I see
I’m a helper for a bunch of masons but I just had the question, “how tf did they build buildings back then?” Well, I got my answer lmao
Why do Americans make everything so dramatic lol
It’s rock n roll baby
What was it's darker use?!?
Right? They tease us and then slap us down!
They mentioned that it was used for war, but not specifically how.
I'm guessing something to do with controlling the decomposition and odors of corpses
I can actually answer that!
Quicklyme was a weapon in medieval warfare, specifically in naval battles. It's very caustic and reacts violently to water, and it can also be made into a fine dust which floats easy in the air. There were two uses of this:
1) If the fine dust got into a cloud (say if you broke a pot of it on an enemy ship or blew it out through bellows), the quick lime reacts (I believe) with the water in the skin and eyes and gives really really bad burns
2) Quicklime can burn up to about 300 C when it touches water, which makes it it really good at setting wet things (i.e. ships) on fire.
isn't it one of the supposed ingredients of Greek fire?
I thought castles used mortar. Never heard of quicklime b4. My mistake!
Yes, later determined it was a kiln-not a castle
The mortar was made from quicklime and reinforced with goat hair.
Trust a channel called science to cram a report full of bullshit instead of sticking to the facts. Come on guys, the facts are interesting enough.
Using quick lime is again invention of India.... Read book 'Varaha Mahira' a complete science of building which has life more than cement and minimum life of 500 yrs
and know we are using fucking poor cement with an average life of 60-70 years 🤷🏻♂️ !!
Vitruvius has a better recipe. His has lasted 2100 years
@@superturkeylegs 500 is minimum , 2500-3000 is maximum , 500is when we only use quicklime mortar , there are many options in ancient time India according to avelibity or raw materials and money rich poor middle class Houses, So don't Compair anyone with ancient indian People's.
@@superturkeylegsGo read History of Egypt and there Trading Roots With india, Many Indian artisans were invited by Egypt as guests to literally guide to make Egypt.
@@superturkeylegs search Indus velly civilization 😂
Knowledge from Africa
we wuz
Just get yourself a bag of NHL 5 😉
Totally with you on that one mate lol

Yeah i made it fast and see for 65 views!
POV: you are here because of "The Story of Edgar Sawtelle"
First
Addison your stole it from India 🙏🇮🇳🕉️
Yeah, the Romans definitely didn't used mortar or anything. Heck I bet they never built walls.
@@nunyabiznes33 They made lime concrete piers and harbors that are still standing. Interestingly, Roman concrete gets stronger over time. Basically, CO2 turns the lime concrete into a composite of sand/pozzolan and limestone. Romans knew about the atom, too.
World old history only indian history. Indian sraview to all country ..in great talent in India technology in art ..stone .. mogals .British. Is destrsier to India hindhu life
