History Of Metallurgy In Africa
African metallurgy has a long history, spanning several millennia and encompassing a wide range of techniques and innovations. This article explores the development and significance of metalworking in different regions of Africa, highlighting the social, economic, and cultural impacts of metallurgical practices. From the earliest use of metals in ancient Egypt to the sophisticated ironworking traditions across sub-Saharan Africa, metallurgy has played a crucial role in shaping African civilizations. Early metallurgy in Africa Prehistoric Metallurgy Evidence of early metallurgical activity in Africa dates back to the 5th millennium BCE. The earliest known use of metals, primarily copper, was likely for ornamentation and tools. Archaeological sites in Niger have revealed copper artefacts dating to this period, showcasing the early adoption of metalworking technologies. Ancient Egypt Ancient Egypt is one of the earliest regions in Africa where metallurgy was significantly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Forging
Forging is a manufacturing process involving the shaping of metal using localized compression (physics), compressive forces. The blows are delivered with a hammer (often a power hammer) or a die (manufacturing), die. Forging is often classified according to the temperature at which it is performed: cold forging (a type of cold working), warm forging, or hot forging (a type of hot working). For the latter two, the metal is heated, usually in a forge. Forged parts can range in weight from less than a kilogram to hundreds of metric tons.Degarmo, p. 389 Forging has been done by metalsmith, smiths for millennia; the traditional products were kitchenware, household hardware, hardware, hand tools, edged weapons, cymbals, and jewellery. Since the Industrial Revolution, forged parts are widely used in mechanism (engineering), mechanisms and machines wherever a component requires high strength of materials, strength; such forgings usually require further processing (such as machining) ...

Iron 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, copper, silver, tin, lead and 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—or, in earlier times, of charcoal. The oxygen in the ore binds to carbon at high temperatures, as the 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 roasted before smelting in order to convert the sulfides to oxides, which are more readily reduced to the metal. Roasting heats the ore in the presence of oxygen from air, oxidizing the ore ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nok Culture
The Nok culture is a population whose material remains are named after the Ham people, Ham village of Nok in Southern Kaduna, southern Kaduna State of Nigeria, where their terracotta sculptures were first discovered in 1928. The Nok people and the Gajiganna people may have migrated from the Central Sahara, along with pearl millet and pottery, and diverged prior to arriving in the northern region of modern-day Nigeria. This may have led to their respective settlements in the regions of Gajiganna and Nok. Nok people may have also migrated from the West African Sahel to the region of Nok. Nok culture may have emerged in 1500 BCE and continued to persist until 1 BCE. Nok people may have developed Nok culture#Sculptures, terracotta sculptures, through large-scale economic production, as part of a complex funerary culture that may have included practices such as feasting. The earliest Nok terracotta sculptures may have developed in 900 BCE. Some Nok terracotta sculptures portray figu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Termit Massif
The Termit Massif (Termit Mountains or simply the Termit) is a mountainous region in south-eastern Niger. Just to the south of the dunes of Ténéré desert and the Erg of Bilma, the northern areas of the Termit, called the Gossololom, consist of black volcanic peaks rising from the surrounding seas of sand. The southern Termit is a roughly east–west ridge of heavily eroded black sandstone. Its foothills to the southwest are the Koutous hills. Location The Termit Massif is located in the Tesker commune in the north-east of the Zinder region. Geographically, the Termite Massif is located in the western part of the Chad Basin. This is where the Sahel desert meets the Sahara. To the north and north-east lie the great sandy deserts of the Ténéré and to the east, behind the Tin-Toumma desert, the Grand Erg du Bilma. South of the mountains is the Dilia de Lagané valley, which runs in a straight line for 200 kilometres. The southern part of the range is characterised by rugge ...

Early Dynastic Period (Egypt)
The Early Dynastic Period, also known as Archaic Period or the Thinite Period (from Thinis, the hometown of its rulers), is the era of ancient Egypt that immediately follows the unification of Upper and Lower Egypt in . It is generally taken to include the First Dynasty and the Second Dynasty, lasting from the end of the archaeological culture of Naqada III until , or the beginning of the Old Kingdom. With the First Dynasty, the Egyptian capital moved from Thinis to Memphis, with the unified land being ruled by an Egyptian god-king. In the south, Abydos remained the major centre of ancient Egyptian religion; the hallmarks of ancient Egyptian civilization, such as Egyptian art, Egyptian architecture, and many aspects of Egyptian religion, took shape during the Early Dynastic Period. Before the unification of Egypt, the land was settled with autonomous villages. With the early dynasties, and for much of Egypt's history thereafter, the country came to be known as "The Tw ...
