Iron Age
The Iron Age () is the final epoch of the three historical Metal Ages, after the Chalcolithic and Bronze Age. It has also been considered as the final age of the three-age division starting with prehistory (before recorded history) and progressing to protohistory (before written history). In this usage, it is preceded by the Stone Age (subdivided into the Paleolithic, Mesolithic and Neolithic) and Bronze Age. These concepts originated for describing Iron Age Europe and the ancient Near East. In the archaeology of the Americas, a five-period system is conventionally used instead; indigenous cultures there did not develop an iron economy in the pre-Columbian era, though some did work copper and bronze. Indigenous metalworking arrived in Australia with European contact. Although meteoric iron has been used for millennia in many regions, the beginning of the Iron Age is defined locally around the world by archaeological convention when the production of Smelting, smelted iron (espe ...

Painted Grey Ware Culture
The Painted Grey Ware culture (PGW) is an Iron Age in India, Iron Age Indo-Aryan people, Indo-Aryan Archaeological culture, culture of the western Gangetic plain and the Ghaggar-Hakra River, Ghaggar-Hakra valley in the Indian subcontinent, conventionally dated 1200 to 600–500 BCE, or from 1300 to 500–300 BCE. It is a successor of the Cemetery H culture and Black and red ware culture (BRW) within this region, and contemporary with the continuation of the BRW culture in the eastern Indo-Gangetic Plain, Gangetic plain and Central India. Characterized by a style of fine, grey pottery painted with geometric patterns in black, the PGW culture is associated with village and town settlements, domesticated horses, ivory-working, and the advent of iron metallurgy. , 1,576 PGW sites have been discovered. Although most PGW sites were small farming villages, "several dozen" PGW sites emerged as relatively large settlements that can be characterized as towns; the largest of these were fort ...

Iron Age In India
In the prehistory of the Indian subcontinent, the Iron Age succeeded Bronze Age India and partly corresponds with the megalithic cultures of South India. Other Iron Age archaeological cultures of north India were the Painted Grey Ware culture (1300–300 BCE) and the Northern Black Polished Ware (700–200 BCE). This corresponds to the transition of the Janapadas or principalities of the Vedic period to the sixteen Mahajanapadas or region-states of the early historic period, culminating in the emergence of the Maurya Empire towards the end of the period. The earliest evidence of iron smelting predates the emergence of the Iron Age proper by several centuries. Region Northern India R. Tewari (2003) radiocarbon dated iron artefacts in Uttar Pradesh, including furnaces, tuyeres, and slag between c. 1000 BCE to 1800 BCE. Antiquity of iron in India was pushed back from following the excavations at Malhar, Raja Nala ka Tila, Dadupur and Lauhradewa in Uttar Pradesh from 1996-200 ...

Smelting
Smelting is a process of applying heat and a chemical reducing agent to an ore to extract a desired base metal product. It is a form of extractive metallurgy that is used to obtain many metals such as iron-making, iron, copper extraction, copper, silver mining#Ore processing, silver, tin, lead smelting, lead and zinc smelting, zinc. Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal behind. The reducing agent is commonly a fossil-fuel source of carbon, such as carbon monoxide from incomplete combustion of coke (fuel), coke—or, in earlier times, of charcoal. The oxygen in the ore binds to carbon at high temperatures, as the Chemical energy, chemical potential energy of the bonds in carbon dioxide () is lower than that of the bonds in the ore. Sulfide ores such as those commonly used to obtain copper, zinc or lead, are roasting (metallurgy), roasted before smelting in order to convert the sulfid ...

Northern Europe
The northern region of Europe has several definitions. A restrictive definition may describe northern Europe as being roughly north of the southern coast of the Baltic Sea, which is about 54th parallel north, 54°N, or may be based on other geographical factors such as climate and ecology. Climate The climate is mainly Oceanic climate (Cfb), Humid continental climate (Dfb), Subarctic climate (Dfc and Dsc) and Tundra (ET). Geography Northern Europe might be defined roughly to include some or all of the following areas: British Isles, Fennoscandia, the peninsula of Jutland, the Baltic region, Baltic plain that lies to the east, and the many islands that lie offshore from mainland northern Europe and the main European continent. In some cases, Greenland is also included, although it is only politically European, comprising part of the Kingdom of Denmark, and not considered to be geographically in Europe. The area is partly mountainous, including the northern volcanic islands ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
