Others say that tourists who urinate on the stones in the rooms leave their mark. According to them, all the walls of our buildings and all our cathedrals built with limestone should be covered with salt. For some Egyptologists, this occurrence of NaCl would be normal since the limestones are sedimented at the bottom of the salty oceans. The presence of NaCl salt is just an anecdote for Egyptology. ” A week later, his daughter confirmed this strange phenomenon to him. The chemist was surprised and replied: “It turns out that my daughter is currently on the Giza site I will send her a message.

He pointed this out to the Head of the Chemistry Department at the Palais de la Découverte in Paris, who was preparing an exhibition on the subject titled: How to build a pyramid, and scheduled for Nov. He repeated the experience on each of his visits, in 1988, 1991, 2003 he shared it with his wife Doris and his son Ralph, who accompanied him and confirmed the issue.

Then he took a piece of geological limestone, tasted it: it was not salty. There was NaCl salt in them, cooking salt. Because he is a chemist, he tasted these stones with his tongue: they were salty. Why is it meaningful? When Davidovits went to the Giza site in 1984, he picked up a few small pieces of stone from the Cheops pyramid. The chemical formula of the microconstituent (mc ’) includes a molecule of NaCl.Įlectron-microscopy SEM of MENK and EDS chemical analysis. It is the presence of halite salt, NaCl (cooking salt), as can be seen in the figure made with the SEM / EDS electron microscopical investigation which gives the chemical structure of the geopolymer glue, located between the numulitic fossil shells. How to get magnesium Mg involved in the geopolymeric chemical reaction? But, there was another chemical element just as important as the others in this MENK sample. Davidovits in June 2004, asking if he had an explanation with respect to their analyzes, in particular the presence of magnesium and the absence of sodium carbonate (natron).

Mykerinos satellite pyramids, sample MENK. It was taken in a large block belonging to a satellite pyramid of Mykerinos (the one in the middle): It consists of numulitic shells, as for the other pyramids. The MENK sample is representative of the blocks forming the core of the pyramids. In the recent study by Barsoum, Gangly and Hug, the core blocks are illustrated by the samples MENK, whereas the casings relate to the LAUER and OC samples. So far, we identified at least two chemical systems, one used for the manufacture of the core blocks (the greatest quantity of stones), the second for the casings. Thanks to the geopolymer chemistry, the chemical reaction generates natural elements, minerals that can be analysed as natural if scientists are not aware of their artificial nature.

People think that because we use chemicals, it is very easy to find these ingredients in the final product. If you want to know how the knowledge evolved after the Pyramids click on Colosses of Memnon The chemical formula: Joseph Davidovits Geopolymer Chemistry & Applications, in several chapters, i.e. The scientific background, including analysis, formula, stone making, are disclosed in the recently updated book by Prof. A geologist not informed of geopolymer chemistry will assert with good faith that the stones are natural. At best, the analysis tools and the working methods of geologists consider the glue as a perfectly natural “micritic binder”.

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.
