#F: Why Djoser’s blue Egyptian faience tiles are not blue?
IXth Egyptology Congress, Grenoble, 2004 Why Djoser’s blue Egyptian faience tiles are not blue? Manufacturing Djoser’s faience tiles at temperatures as low as 250°C? by Joseph Davidovits and Ralph Davidovits 30,000 blue faience tiles were found in Djoser’s funerary complex at Saqqarah (3. dynasty). It is generally assumed that the tiles underwent a self-glazing process [...]

Les mortiers de pouzzolanes artificielles chez Vitruve: évolution historique et archirtecturale DEA thesis by Frédéric Davidovits, université de Nanterre – Paris X, 1993 ( in French, en Français ) Contrairement à ce que l’on croit généralement, les sables employés dans les mortiers dits hydrauliques chez les romains sont de nature pouzzolaniques car d’origine volcanique. Des [...]
#C: Making Cements with Plant Extracts
Fabrication of stone objects, by geopolymeric synthesis, in the pre-incan Huanka civilization (Peru) Joseph DAVIDOVITS and Francisco ALIAGA Abstract of a paper presented at the 21st International Symposium for Archaeometry, Brookhaven National Laboratory, New York, USA, 1981 (page 21). It is now agreed, that the TIHUANACO civilisation is modeled on the pre-incan HUANKA civilisation revealed [...]
#B: Famine Stele and the construction of Pyramids with man-made stone
Vth Egyptology Congress, Cairo, 1988 The Famine Stele and the construction of Pyramids with man-made stone by Joseph Davidovits Egyptologists have long claimed that no records exist which describe how the Pyramids were built. A stone stela is engraved on a rock at the island Sehel, near Elephantine, Egypt, north of Aswan. It was discovered [...]
