The Land of Khem: the Birthplace of Chemistry

It isn't often when you can pinpoint the beginning of anything, but chemistry was an invention of the ancient Eqyptians. With a handfull of natural chemicals both organic from plants and inorganic from minerals the people of the land of Khem passed down the science of chemistry

The land of Khem was the actual name for ancient Egypt. This is what the everyday Egyptians called the country where they lived. You would never suspect it today, but the name lives on in the word chemistry. Thousands of years ago people of Khem were among the first practitioners of the art of chemistry. It was recently discovered how highly developed their chemistry was. From the studies of Prof. Joseph Davidovits of France to get an idea of how highly developed it really was.

Prof. Davidovits discovered an ancient technology Egyptians used to cast some of the stones found in the Great Pyramid at Giza. It is a form of concrete that was cast in place rather than dragging them up long slippery inclines of mud by thousands of sweating slaves. He has named this method of making concrete geopolymers that are an alumino-silicate analogue of Portland cement.

The ancient Egyptian priests many of whom were skilled alchemists were capable of taking some common chemical compounds that were found in Egypt and its environs and make them perform in ways that seemed magical including making the ancient Egyptian equivalent of concrete. The technique the Egyptians used to make their concrete was apparently even ancient in their day as the use of has been traced back for over 25,000 years.

Prof. Davidovits experiments with some similar limestone to that found in Egypt with some from northern France was even able to duplicate the fossils in the limestone like that in the blocks of the Great Pyramid. The Egyptians were able to synthesize a particular chemical technique needed to carry this process forward from a common substance was found in the surrounding deserts in large quantities.

The author, himself has performed a number of experiments dealing with geopolymers that did verify a great deal of work that was done by the ancient Egyptians through his own experiments.

The Egyptians developed some of the processes used in chemistry that we use today. These processes have been handed down through the ages since the time of ancient Egypt when they were building the pyramids. Building pyramids wasn't the only trick that the Egyptians did with their chemistry. Among some of the other things they did was to mummify their dead, devise various ways to preserve their food, do their cooking and baking, make beer and wine, tan leather and to invent the pigments used in cosmetics and paint.

It was from their legacy of using chemicals that they have handed down to us among the many laboratory utensils that are still used in a modern lab, notable among them was the use of the beaker. It was also the ancient Egyptians that developed the use of a blow pipe that was the only method of making a really hot flame until he invention of the Bunsen burner in 1860. Many other pieces of intricate gold jewelry were soldered using the flame of a blowpipe.
