History of Metallurgy - Trivia For Your Brain
What do we know about metallurgy? Metallurgy is that branch of science that deals with the procedures used when extracting metals from their ores, purifying and alloying them. This also involves the study of the procedures used when making objects out of metals. Yet, to be able to understand fully what metallurgy is all about, it would be better to have a short glimpse of the history of metallurgy. One of the oldest processes of applied science is the process of metallurgy. Its history would give us a good view of how the process developed and its association with metals. The history of metallurgy can be dated back to 7,000 BC which is what they call the age of copper. It is the period between the Stone Age and the Bronze Age which could also be considered the turning point between Stone to Metal.

Metallurgy - What is It?
Metallurgy is the art and science that deals in extracting metals from their ores, alloying and getting the impurities of the metal and transform the metals to a more useful object. It is also the study of metals, its physical and chemical properties, the atomic structure and the process on how to combine to produce an alloy. There are two phases to extract the metal from its ore this includes mineral processing and process metallurgy. During the mineral processing, desired broken elements are extracted from the broken ore. The minerals are created to produce an alloy and metal to a more useful form during the metallurgy process. Metallurgy is divided into two processes, the process metallurgy and the physical metallurgy. Process metallurgy includes the system metal processing while in physical metallurgy includes the mechanical behavior of the metals.

Boric Acid
Boric acid is made out of hydrogen (three parts), oxygen (three parts), and one part boron. Boron, like oxygen and hydrogen, occurs naturally in the water, air, and soil. Most people actually eat a small amount of boron every day without realizing it. Boric Acid Silly Putty The most famous boric acid product is silly putty. It s a mixture of silicone oil and boric acid. It was developed by accident by James Wright (G.E. engineer). Common Uses Boric acid is used in a lot of ways. Here are some of the most common: ndash Pharmaceuticals ndash nutritional supplements ndash flame retardants ndash metallurgy ndash glass ndash wood preservative ndash flame retardants. Roaches Most people discover boric acid the first time they have a roach problem. It is the simplest and least toxic way to eliminate roaches.

Silver Gemstone Jewelry History In Neolithic India
In the majority of Neolithic India, as in most parts of the world at that time, people fashioned jewelry out of seeds, feathers, berries, flowers, bones and shells. But in the north of India, in the Indus valley cities of Mohenjo ndash daro and Harappan, men and women were already wearing jewelry made of gold, silver, copper and set with precious and semi ndash precious gemstones. The Indus valley civilization, preceding the Vedic, existed from 3000 B.C. to 1500 B.C., and was built in and amongst the fertile lands of what is known today as Pakistan. The Neolithic Indus valley people like others, domesticated animals and harvested crops of cotton, sesame and barley. Contrary to the belief that India only possessed an agricultural economy in this period, evidence has been found at the Indus cities of Mohenjo ndash daro and Harappan, showing the people as having been sophisticated urbanites whose cities were bastions to art and culture.

What is Chemistry
Chemistry is the science of substances, or materials, their composition and characteristics, and the reactions which take place between those substances. It is concerned with chemical elements in their pure state and when they are combined, that is, reactions of these elements and the compounds which they form. The scientist who wants to do chemistry must first be able to understand its building blocks, substances in their pure state. Only then can the chemist use that knowledge to comprehend more complicated phenomena, and begin to perform his own experiments. Every chemical reaction can be represented with the help of atoms and molecules. It was necessary, therefore, to develop a special system of chemical symbols. Substances in their pure state, called elements, were sometimes named after the scientists who discovered them. From those names, abbreviations were derived (like O for oxygen).

What is Chemistry?
Put it simply Chemistry is the study of matter and the way matter changes. The word Chemistry comes from an ancient Egyptian word khemeia. Khemeia was an Egyptian art which occurs in various Egyptian groups that was connected to mummification. Later along the history, its practices included things such as dyeing, metallurgy and glass making. Although the ancients knew of copper, silver, gold, tin, lead, iron, carbon and sulphur, they did not know that these are elements. To them, they follow the teachings of the 5th century BC Greek thinker and philosopher Empedocles and popularized by Aristotle. To them, matter was made up of four elements ndash the earth, air, fire and water. To them this classification made sense because after all, earth is not a solid, water is not a liquid, air not a gas and fire not an energy.

Santorini - Bronze Age (3200-1100 BC)
The early Bronze Age in the Aegean, also known as the Early Cycladic period, is divided into sub ndash periods, corresponding primarily to the advances in pottery techniques and design. By the first period of the Bronze Age (Halcolithic Age), the Cyclades had already developed a culture with its own distinct features. The expansion of shipping and trade between 2800 ndash 2700 BC generated the growth of ports, which became small urban centers. Besides Phylakopi on Milos, other centers were Akrotiri on Santorini, Aghia lrin on Kea, Parikia on Paros, and so on. Fortified settlements also appeared, such as at Kastri on Syros, Panormos on Naxos, Kynthos on Delos, Halandriani on Syros, and so far on. But these settlements did not last long and came to violent ends. As a result, artistic creation in the Aegean was suspended and the settlements did not evolve into city ndash states.
