In Sept. 2004, at the IXth International Congress of Egyptologists, Grenoble, France, Prof. Joseph Davidovits and Dr. Frederic Davidovits presented several papers depicting the chemical knowledge of the Egyptians involved in pyramid building.
One was dedicated to the manufacture of the famous blue faience tiles, like those adorning the subterranean galleries of the Djoser Step-Pyramid at Saqqarah : See in the Library the paper IXth Egyptology Congress, Grenoble, 2004: The manufacture of Egyptian Blue Faience Tiles .
The second paper dealt with the famous Herodotus text; see the paper IXth Egyptology Congress, Grenoble, 2004: Herodotus and Pyramid construction (“Construction des pyramides d’après Herodote”), in French.
