Cutting-Edge analysis proves Davidovits’ Pyramid theory
On November 30, the Journal of the American Ceramic Society has released a very important scientific research carried out on the pyramid stones, which confirms the theory developed by Professor Joseph Davidovits on agglomerated (artificial) limestone concrete (ancient geopolymer). The references of this paper are : Barsoum, M. W., Ganguly, A. & Hug, G. (2006), [...]
25.000 years old : a geopolymer ceramic ?
The oldest ceramic ever manufactured, the Venus of Dolni Vestonice, is displayed at the Anthropology Museum, at Brno, Czech Republic. The Venus of Dolni Vestonice was visited by Prof. Joseph Davidovits who writes: ” I still had for my eyes the image of the yellow limestone Venus displayed at the Vienna Museum, Austria, to be [...]
The making of brown-black ceramics with LTGS in prehistory and antiquity
At the 1980, 1981, 1982, and 1984 Symposia on Archaeometry, Joseph Davidovits showed the possibility of fabricating ceramics by Low Temperature Geopolymeric Setting between 50°C and 500°C. The results obtained with LTGS have been surprising and very interesting from the archaeological point of view, e.g. the fabrication of ceramic whose surface is covered by an [...]
#H: the making of black-brown Etruscan ceramic, LTGS analogue

Pyramids (3) The formula, the invention of stone
Why do geologists see nothing? This is due to the geological glue, which, though artificial, is seen by the geologists either as an impurity, and therefore useless to study, or as a natural binder. At best, the analysis tools and the working methods of geologists consider the glue as a perfectly natural “micritic binder”. A [...]
The Famine Stele: hieroglyphs on pyramids construction
Summary of the Conference by Joseph Davidovits Vth International Congress of Egyptology, Cairo, Egypt, Oct. 29-Nov.3, 1988. Egyptologists have long claimed that no records exist which describe how the Pyramids were built. A stone stele is engraved on a rock at the island Sehel, near Elephantine, Egypt, north of Aswan. It was discovered in 1889 [...]
High performance Roman cement and concrete, high durable buildings

Concrete experts talk today about how to make concrete durable. Many ancient Roman concrete buildings are still in use after more than 2000 years. For these modern concrete experts, the [...]
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 [...]
Papers dedicated to archaeology in Geopolymer Proceedings
Brief summary of the papers dedicated to archaeology and published in the Geopolymer Proceedings : Geopolymer 2005 and Geeopolymer ‘99 Geopolymer 2005 Synthetic stone in Ancient Egypt and Mesopotamia manufacture of synthetic lava and synthetic basalt and decipherment of the C-14 Irtysen Stele (2000 B.C.)

The geopolymer chemistry was known during antiquity
Joseph Davidovits has found revolutionary ways of producing cements with plants saps, which could explain some of the mysteries associated with Pre-Columbian architectures. Preliminary results had been presented at two International Archaeometry Symposia. See in the library the paper #C Making Cements with Plant Extracts disclosing information dating back to 1981 and 1982. In 1979, [...]
