Pañcadhātu
''Panchaloha'' (), also called ''Pañcadhātu'' (), is a term for traditional five-metal alloys of sacred significance, used for making Hindu temple ''murti'' and jewellery. Composition The composition is laid down in the ''Shilpa shastras'', a collection of ancient texts that describe arts, crafts, and their design rules, principles and standards. Panchaloha is traditionally described as an alloy of gold, silver, copper, zinc, and iron. It is believed that wearing jewellery made of such an alloy brings balance in life, self-confidence, good health, fortune, prosperity, and peace of mind. In Tibetan culture, it was considered auspicious to use ''thokcha'' (meteoric iron Meteoric iron, sometimes meteoritic iron, is a native metal and early-universe protoplanetary-disk remnant found in meteorites and made from the elements iron and nickel, mainly in the form of the mineral phases kamacite and taenite.

Iron
Iron is a chemical element; it has symbol Fe () and atomic number 26. It is a metal that belongs to the first transition series and group 8 of the periodic table. It is, by mass, the most common element on Earth, forming much of Earth's outer and inner core. It is the fourth most abundant element in the Earth's crust, being mainly deposited by meteorites in its metallic state. Extracting usable metal from iron ores requires kilns or furnaces capable of reaching , about 500 °C (900 °F) higher than that required to smelt copper. Humans started to master that process in Eurasia during the 2nd millennium BC and the use of iron tools and weapons began to displace copper alloys – in some regions, only around 1200 BC. That event is considered the transition from the Bronze Age to the Iron Age. In the modern world, iron alloys, such as steel, stainless steel, cast iron and special steels, are by far the most common industrial metals, due to their mechan ...

Zinc Alloys
Zinc is a chemical element; it has symbol Zn and atomic number 30. It is a slightly brittle metal at room temperature and has a shiny-greyish appearance when oxidation is removed. It is the first element in group 12 (IIB) of the periodic table. In some respects, zinc is chemically similar to magnesium: both elements exhibit only one normal oxidation state (+2), and the Zn2+ and Mg2+ ions are of similar size. Zinc is the 24th most abundant element in Earth's crust and has five stable isotopes. The most common zinc ore is sphalerite (zinc blende), a zinc sulfide mineral. The largest workable lodes are in Australia, Asia, and the United States. Zinc is refined by froth flotation of the ore, roasting, and final extraction using electricity ( electrowinning). Zinc is an essential trace element for humans, animals, plants and for microorganisms and is necessary for prenatal and postnatal development. It is the second most abundant trace metal in humans after iron, an important c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hindu Iconography
Over the millennia of its development, Hinduism has adopted several iconography, iconic symbols, forming part of Hindu iconography, that are imbued with spiritual meaning based on either the Hindu scriptures, scriptures or cultural traditions. The exact significance accorded to any of the icons varies with region, period and denomination of the followers. Over time some of the symbols, for instance the Swastika has come to have wider association while others like Om are recognized as unique representations of Hinduism. Other aspects of Hindu iconography are covered by the terms murti, for icons and mudra for gestures and positions of the hands and body. Hindu sacraments Hindu sacraments are physical pieces of that help objects or markings that are considered sacred and used as a sign of devotion by the followers of Hinduism. These are often objects associated with a puja (Hinduism), puja (prayer) or religious ceremony. Murti Murtis (Sanskrit: मूर्ति) are sa ...

Copper Alloys
Copper alloys are metal Alloy, alloys that have copper as their principal component. They have high resistance against corrosion. Of the large number of different types, the best known traditional types are bronze, where tin is a significant addition, and brass, using zinc instead. Both of these are imprecise terms. Latten is a further term, mostly used for coins with a very high copper content. Today the term ''copper alloy'' tends to be substituted for all of these, especially by museums. Copper deposits are abundant in most parts of the world (globally 70 parts per million), and it has therefore always been a relatively cheap metal. By contrast, tin is relatively rare (2 parts per million), and in Europe and the Mediterranean region, and even in prehistoric times had to be Tin sources and trade during antiquity, traded considerable distances, and was expensive, sometimes virtually unobtainable. Zinc is even more common at 75 parts per million, but is harder to extract from its ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iron Meteorite
Iron meteorites, also called siderites or ferrous meteorites, are a type of meteorite that consist overwhelmingly of an iron–nickel alloy known as meteoric iron that usually consists of two mineral phases: kamacite and taenite. Most iron meteorites originate from cores of planetesimals, with the exception of the IIE iron meteorite group. The iron found in iron meteorites was one of the earliest sources of usable iron available to humans, due to the malleability and ductility of the meteoric iron, before the development of smelting that signaled the beginning of the Iron Age. Occurrence Although they are fairly rare compared to the stony meteorites, comprising only about 5.7% of witnessed falls, iron meteorites have historically been heavily over-represented in meteorite collections. This is due to several factors: * They are easily recognized as unusual, as opposed to stony meteorites. Modern-day searches for meteorites in deserts and Antarctica yield a much more repre ...

Thokcha
''Thokcha'' (; also alternatively ) are Tibetan amulets which are said to have fallen from the sky in traditional Tibetan folklore. These are traditionally believed to contain a magical, protective power comparable to Tibetan dzi beads. Most ''thokcha'' are made of a copper alloy. The use of meteoric iron has been common throughout the history of ferrous metallurgy. Historically, ''thokcha'' were prized for the metallurgical Fabrication (science), fabrication of weapons, musical instruments, and sacred tools, such as the ''phurba''. ''Thokcha'' are an auspicious addition in the metallurgical fabrication of sacred objects cast from ''panchaloha''. Writer Robert Beer regards meteoric iron as "the supreme substance for forging the physical representation of the ''vajra'' or other iron weapons." It was believed that these amulets had been tempered by the celestial gods before falling to Earth. Beer describes the metal falling from space as a metaphor for "the indivisibility of fo ...

Tibetan Culture
Tibet developed a distinct culture due to its geographic and climatic conditions. While influenced by neighboring cultures from China, India, and Nepal, the Himalayas, Himalayan region's remoteness and inaccessibility have preserved distinct local influences, and stimulated the development of its distinct culture. Tibetan Buddhism has exerted a particularly strong influence on Tibetan culture since its introduction in the seventh century. Buddhist missionaries who came mainly from India, Nepal and China introduced arts and customs from India and China. Art, literature, and music all contain elements of the prevailing Buddhist beliefs, and Buddhism itself has adopted a unique form in Tibet, influenced by the Bön tradition and other animism, local beliefs. Several works on astronomy, astrology and medicine were translated from Sanskrit and Classical Chinese. The general appliances of civilization have come from China, among many things and skill imported were the making of bu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Alloys
An alloy is a mixture of chemical elements of which in most cases at least one is a metallic element, although it is also sometimes used for mixtures of elements; herein only metallic alloys are described. Metallic alloys often have properties that differ from those of the pure elements from which they are made. The vast majority of metals used for commercial purposes are alloyed to improve their properties or behavior, such as increased strength, hardness or corrosion resistance. Metals may also be alloyed to reduce their overall cost, for instance alloys of gold and copper. A typical example of an alloy is 304 grade stainless steel which is commonly used for kitchen utensils, pans, knives and forks. Sometime also known as 18/8, it as an alloy consisting broadly of 74% iron, 18% chromium and 8% nickel. The chromium and nickel alloying elements add strength and hardness to the majority iron element, but their main function is to make it resistant to rust/corrosion. In an al ...

Copper
Copper is a chemical element; it has symbol Cu (from Latin ) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins, and constantan used in strain gauges and thermocouples for temperature measurement. Copper is one of the few metals that can occur in nature in a directly usable, unalloyed metallic form. This means that copper is a native metal. This led to very early human use in several regions, from . Thousands of years later, it was the first metal to be smelted from sulfide ores, ; the first metal to be cast into a shape in a mold, ; and the first metal to be purposely alloyed with another metal, tin, to create bronze, ...
