Iron Pigments Through The Ages, Fathi Habashi
Iron Pigments Through The Ages, Fathi Habashi
Fathi Habashi
Naturally occurring iron oxides were used since ancient times as ochre yellow and red pigments. It was only in the 18th century that artificially prepared Prussian blue was discovered. This discovery opened up a new field of chemistry - - cyano compounds.

A Short History Of Uranium, Fathi Habashi
A Short History Of Uranium, Fathi Habashi
Fathi Habashi
Uranium was discovered in 1781 by Klaproth, a pharmacist in Berlin, from the black mineral pitchblende found in Joachimsthal silver mines. Peligot in France in 1841 proved that what Klaproth isolated from pichblende was uranium oxide and not the metal. Uranium salts were used at that time to manufacture coloured glass before the discovery of its radioactivity in 1896. It became in great demand when its decay product radium was found to cure cancer. The discovery if uranium fission in 1939 was the reason for the manufacture of the first atomic bomb.
Mining And Civilization, Fathi Habashi
Mining And Civilization, Fathi Habashi
Fathi Habashi
Ancient ruins or an ancient stone statue recalls the work of miners who brought the material from a quarry so that the sculptor can create a work of art. Carving of massive stone blocks and piercing tunnels in mountains are arts in which the same tools of mining are used and mining engineers are involved. Studying history of mining necessitates also the study of archaeology, art, architecture, and world history in general since it is the history of civilization. The pyramids of Egypt, the gold of Tut Ankh Amoun, the Coloseum in Rome, the Taj Mahal in Agra, and the …
The Pyramids Of Egypt, Fathi Habashi
The Pyramids Of Egypt, Fathi Habashi
Fathi Habashi
The Great Pyramid in Egypt built about two thousand years BC is not just a pile of stones. It is a grave containing a burial chamber, passages, and ventilation ducts, etc. It is an engineering feat. It took many centuries of experimentation till it was possible to build a true pyramid. There are about one hundred pyramids in Egypt. After about 500 years when the Egyptians stopped building pyramids, the Nubans who occupied Egypt around 1000 BC, built in Meroe another two hundred pyramids but far much smaller than those at Memphis.
Movement Of Scientists And The Production Of Aluminum, Fathi Habashi
Movement Of Scientists And The Production Of Aluminum, Fathi Habashi
Fathi Habashi
Travelling scientists certainly have contributed to advancing knowledge by communicating their observations to others. Famous professors attract students from different countries to study in their institutions and the interaction among these students is of immense importance in the diffusion of knowledge. The invention of a process for the production of aluminum is an example.
Story Of Metals, Fathi Habashi
Story Of Metals, Fathi Habashi
Fathi Habashi
Metals are not arranged according the Periodic Table or alphabetically but are arranged according to their discovery. There are two introductory chapters on metals and their history: Part 1. Metals Part 2. History of Metals and Metallurgy Part 3. Ancient Metals Part 4. Metalloids of the Alchemists Part 5. Metals from South America Part 6. Metals from the East Part 7. Eighteenth Century Metals Part 8. Metals of the Nineteenth Century Part 9. Twenty century metals The book is illustrated by many Figures mostly in color, biographies of many chemists and metallurgists, and many flowsheets of processes.
Joseph William Mellor (1869-1938) - - A Pioneer Ceramicist, Fathi Habashi
Joseph William Mellor (1869-1938) - - A Pioneer Ceramicist, Fathi Habashi
Fathi Habashi
Mellor is known to chemists as the author of the monumental work on General and Inorganic Chemistry but he is also a pioneer ceramicist. It was under his direction in 1920 that the British Refractories Research Association was formed which eventually became in 1948 the British Ceramic Research Association. Mellor spent most of his professional career at Stoke-on-Trent working on pottery.
