The 1st International Forum Ceramics & Brotherhoods was held on July 4, 2008, Verona, Italy, during the 2nd International Congress on Ceramics ICC2. It involved representatives of African Countries (Kenya, Liberia, Tanzania) and European scientists. The aim of Ceramics & Brotherhoods is the transfer of appropriate ceramic technologies to African Countries. I am member of [...]

The famous Massachusetts Institute of Technology, Boston, USA, is supporting my re-agglomerated stone (concrete) pyramid theory. At MIT, Professor Hobbs and two colleagues and students are experimenting the construction of a small scale pyramid using my theory. Go to the Boston Globe article of April 22 2008 titled A new angle on pyramids Scientists explore [...]

Three basically different theories on pyramid construction were all validated « scientifically with 3D simulation « . Accordingly, all three would be exact and explain the true methods used by the ancient Egyptians. Actually, it would mean that none of them is accurate, because science cannot validate at the same time several theories, which are fundamentally different and opposite in their concepts.

The world press is commenting the study published by the French science magazine Science & Vie and the scientific paper released by the Journal of the American Ceramic Society , December 2006. Here some links and excerpts from major English, American and German news papers Materials Science: Concrete evidence The scientific magazine NATURE, vol. 444, [...]

It is obvious that, with his statement published on December 1, 2006, in the New York Times , Dr. Hawass, General Secretary of the Egyptian Antiquity Organisation, thought that the renowned material scientists, professors M. Barsoum, G. Hug and G. Demortier, had analyzed modern Portland cement concrete instead of the re-agglomerated (reconstituted) limestone, as claimed [...]

Walter Sullivan, science editor and writer at the New York Times, was the first English speaking journalist to write that the Egyptian pyramids may have been cast from plastic rock instead of being hewn. I have been attending the International Archaeometry Symposium, held at the Brookhaven National Laboratory, Long Island from May 18 to May [...]

In the USA, and consequently in the English scientific journals, my invention of the geopolymer chemistry in the years 1970-80 is narrated like a fairy tale. According to it, it was during my study of the pyramids of Egypt that, Eureka, I got this intuition. In America, the fundamental and applied researches on geopolymers are [...]

Last year, the Nobel Prize of medicine and physiology 2005 was awarded jointly to Barry Marshall and Robin Warren, two Australian researchers who discovered the role of the bacterium Helicobacter pylori in the formation of stomach or duodenum ulcers. Before Marshall and Warren identify this bacterium, at the beginning of the Eighties, way of life [...]

It is with sorrow that I learned that my friend Georges Grimal died at the age of 98 years. The majority of our scientific colleagues, engineers and students, know at least one of his works of Art created with geopolymer.

Continuing my visits to the Czech scientific institutions, I met with Professor Miroslav Verner, professor of egyptology, director of the Czech Institute of Egyptology.

The oldest prehistoric statue, the Venus from Dolni Vestonice (Czech Republic), made out of a ceramic of the geopolymeric type, manufactured at 300-400°C, in an open wood fire.

Geopolymer applications and archaeology summarized in a 9 min. interview (in English)
