“Khusi-to build in reagglomerated stone, and this is what we get as sentence in the Famine Stele: "with these products (that are depicted in the... columns in hieroglyphs) they have built the pyramid (the royal tomb)." Which pyramid? It is the first... of ... built by ... It is the first pyramid, the step pyramid at ... made of small limestone bricks... manufactured like crude clay bricks.

“[L]ime is very important and it has been shown by [(1990) Professor D.D.] Klemm: "...in the VI. Dynasty lime disappears nearly within the mortars. May this be interpreted as a variation in the accessibility of fuel [of wood] and consequently of economic potential and crisis?" ...He was talking about the regular lime that is calcined from limestone in a kiln. ...[W]e have not found any remains of kilns... to manufacture the pyramids of Cheops and Chephren. We need... 150,000 tons of lime, which means that we should have found remains of kilns. We did not... which means that the technology was different. ...[I]t was the one of ashes that contains lime... The ecological disaster came from the over-exploitation of wood... proven by the fact that just after the Great Pyramids, one gets frescoes... describing famines...”

“So we started with mud bricks that were used in the enclosures during the 2nd Dynasty. They did not have stone [working, hard metal] tools so... they used mud bricks. Then... the invention of the first limestone bricks by agglomeration. The technology improved into bigger and bigger... limestone blocks, and then suddenly, 800 years later, they had tools to cut the stone. No! They returned to pyramids made of mud brick. So this is something is not capable of explaining. It is something that ic technology is capable of explaining, essentially because here we had a stop of the use of this technology to make stone.”

“What about the Cheops pyramid? ...We have the core, this is the mass, more than 2 million tons ...made of ...reagglomerated limestone. But ...in the ...inner ...it is made of granite ...carved stone. Why? Cheops... is Khnum Kufu... agglomerated stone. However, Pharaoh is the king of the two countries. ...[T]he pyramids must be the representation of Egypt,... which means ...the replication of agglomerated stone for the northern part ....and in the south, natural granite that is the carving technology. So we have agglomerated limestone for the core, and the King's chamber is made of split granite that is dressed [cut] ...not carved granite.”
