One of the St Paul's Cathedral masons gives us a close look at carvings on the outside of the building, a perspective that is only available when you are up on some high scaffolding.
There’s so much in this world that people take for granted or see and don’t even think about the hard work that goes into so many different things. That’s some beautiful stone right there
I do stone masonry at 7000+ ft elevation. The cement dries to fast usually 15 minutes is too long and you get grey cement. Here is what I do about that: Take the cement residue in the bucket mix it with saw dust and just enough water to saturate the wood shavings, mix them together and apply it to the joints. It sticks and when you come back in a couple weeks it comes out perfect. Every single time.
If you think that this carvig is one of the finest you can find, just go and have a look at the choir of the Cathedral of Albi, in France. It's not stone carving, it's litterally stone lace, a work I never saw anywhere else.
No not geopolymer, that was debunked worldwide, all the ancient stoneworks are hand made with basic tools, even those in egypt and in central america, all of the monuments have tool marks including baalbek in Libanon. It took many skilled men who back then had higher grade dna(dna get's worse and worse with every generation).
Are you okay? There's extensive documentation of the construction of this cathedral. It was only completed in 1710. I believe you've confused it with a conspiracy based around the pyramids in Egypt. You're definitely wrong about that as well. Egyptians didn't know how to make cement or they would have written about it in the Pyramid Texts. We know how they built them because they have literally already told us. We've literally found wooden sleds used to haul the stones, and have found texts describing how they were used. The pyramids were built using cut stone and some fill dirt. Final answer.
