Kestel is an archaeological site in the Taurus Mountains in Turkey, with important finds related to the study of Tin sources and trade in ancient times.
Kestel is a probable site of Bronze Age tin mining in the Bolkar range of the Taurus Mountains in Anatolia (near the present village of Celaller, Çamardı District, Niğde Province, Turkey). Tin in the Bronze Age was as scarce and valuable as petroleum is today. It was a vital ingredient of bronze, used with copper to make the alloy.
K. Aslihan Yener spent years in archaeometallurgy surveys together with the Turkish Geological Survey (MTA) and found cassiterite (tin ore) crystals in a stream in the Taurus foothills. This ore is purple; previous searches had been looking for black ore because most tin ores are black. Near the site was a deserted valley with a hill called Kestel that proved to hold a tin mine. Additionally, fragments of Bronze Age pottery were found in and near the mine. Inside, there were veins of bright purple tin ore.
The Kestel mine has two miles (3 km) of tunnels, many of which are only about two feet wide, just large enough to allow children to do the mining work. In one abandoned shaft, a burial of twelve to fifteen children was found, presumably killed while working in the mine.
In 1989, on the on top of a large natural hill called Göltepe located 2 km opposite the Kestel mine ( 37°48′04″N34°56′02″E / 37.801°N 34.934°E ), associates found piles of Bronze Age pottery, close to 50,000 ground stone tools and evidence that this site had been continuously occupied from 3290–1840 BC. The hill measures close to 60 hectares and is fortified at the summit, with cultural deposition throughout the entire extent of its surface. The size of the settlement is estimated to be 8-10 hectares, and combined with the Kestel slope occupation probably totals 60 hectares in a man+mine system. A great deal of the city was semi subterranean.
The pottery at Göltepe provided the final proof of the tin industry in the Bronze Age. Many thick crucibles lined with slag were found at the site and tests revealed the slag to have very high concentrations of tin (30% to almost 100%). It is likely that after the ore nuggets were washed, stone tools were used to grind them to a powder, and then the powder was heated to melt out the tin. All of this can be accomplished with Bronze Age tools and methods. The Kestel mine stopped producing at the end of the third millennium BC.
J.D. Muhly has criticized the reconstruction proposed by Yener. He noted that no ores with high tin mineral contents were found; that the ores found may be more useful for iron mining; that the radiocarbon dating provided allows for setting the expansion of the mine in a much later time; that no significant bronze artefact are known from southeastern Anatolia in the Early Bronze Age; that tin extraction with the Kestel crucibles would require manipulation of microscopic slag particles; that Middle Bronze Age Assyrian records point to tin trade - sourced in the east - that extended into Anatolia; that no textual evidence of any period refers to tin extraction on Anatolia.

The Chalcolithic is an archaeological period characterized by the increasing use of smelted copper. It follows the Neolithic and precedes the Bronze Age. It occurs at different periods in different areas, and is absent in some parts of the world, such as Russia. Stone tools were still predominantly used during this period.
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, 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.
The Taurus Mountains are a mountain complex in southern Turkey, separating the Mediterranean coastal region from the central Anatolian Plateau. The system extends along a curve from Lake Eğirdir in the west to the upper reaches of the Euphrates and Tigris rivers in the east. It is a part of the Alpide belt in Eurasia.
Alalakh is an ancient archaeological site approximately 20 kilometres (12 mi) northeast of Antakya in what is now Turkey's Hatay Province. It flourished, as an urban settlement, in the Middle and Late Bronze Age, c. 2000-1200 BC. The city contained palaces, temples, private houses and fortifications. The remains of Alalakh have formed an extensive mound covering around 22 hectares. In Late Bronze Age, Alalakh was the capital of the local kingdom of Mukiš.
The Uluburun Shipwreck is a Late Bronze Age shipwreck dated to the late 14th century BC, discovered close to the east shore of Uluburun, Turkey, in the Mediterranean Sea. The shipwreck was discovered in the summer of 1982 by Mehmed Çakir, a local sponge diver from Yalıkavak, a village near Bodrum.
Tell Ta'yinat is a low-lying ancient tell on the east bank at the bend of the Orontes River where it flows through the Amuq valley, in the Hatay province of southeastern Turkey about 25 kilometers south east of Antakya, and lies near Tell Atchana, the site of the ancient city of Alalakh. Tell Ta'yinat has been proposed as the site of Alalaḫu, inhabited in late 3rd millennium BC, mentioned in Ebla's Palace G archive; and in later times as Kinalua, the capital city of an Iron Age Neo-Hittite kingdom.
Cupellation is a refining process in metallurgy in which ores or alloyed metals are treated under very high temperatures and subjected to controlled operations to separate noble metals, like gold and silver, from base metals, like lead, copper, zinc, arsenic, antimony, or bismuth, present in the ore. The process is based on the principle that precious metals typically oxidise or react chemically at much higher temperatures than base metals. When they are heated at high temperatures, the precious metals remain apart, and the others react, forming slags or other compounds.
K. Aslıhan Yener, often anglicised as K. Aslihan Yener, is a Turkish American archaeologist whose work on Bronze Age tin mines in Anatolia revealed a new possible source of the important metal.
Mining in Cornwall and Devon, in the southwest of Britain, is thought to have begun in the early-middle Bronze Age with the exploitation of cassiterite. Tin, and later copper, were the most commonly extracted metals. Some tin mining continued long after the mining of other metals had become unprofitable, but ended in the late 20th century. In 2021, it was announced that a new mine was extracting battery-grade lithium carbonate, more than 20 years after the closure of the last South Crofty tin mine in Cornwall in 1998.
Oxhide ingots are heavy metal slabs, usually of copper but sometimes of tin, produced and widely distributed during the Mediterranean Late Bronze Age (LBA). Their shape resembles the hide of an ox with a protruding handle in each of the ingot’s four corners. Early thought was that each ingot was equivalent to the value of one ox. However, the similarity in shape is simply a coincidence. The ingots' producers probably designed these protrusions to make the ingots easily transportable overland on the backs of pack animals. Complete or partial oxhide ingots have been discovered in Sardinia, Crete, Peloponnese, Cyprus, Cannatello in Sicily, Boğazköy in Turkey, Qantir in Egypt, and Sozopol in Bulgaria. Archaeologists have recovered many oxhide ingots from two shipwrecks off the coast of Turkey.
Metals and metal working had been known to the people of modern Italy since the Bronze Age. By 53 BC, Rome had expanded to control an immense expanse of the Mediterranean. This included Italy and its islands, Spain, Macedonia, Africa, Asia Minor, Syria and Greece; by the end of the Emperor Trajan's reign, the Roman Empire had grown further to encompass parts of Britain, Egypt, all of modern Germany west of the Rhine, Dacia, Noricum, Judea, Armenia, Illyria, and Thrace. As the empire grew, so did its need for metals.
Yener is a Kurdish name. Notable people with the name include:
Tin is an essential metal in the creation of tin-bronzes, and its acquisition was an important part of ancient cultures from the Bronze Age onward. Its use began in the Middle East and the Balkans around 3000 BC. Tin is a relatively rare element in the Earth's crust, with about two parts per million (ppm), compared to iron with 50,000 ppm, copper with 70 ppm, lead with 16 ppm, arsenic with 5 ppm, silver with 0.1 ppm, and gold with 0.005 ppm. Ancient sources of tin were therefore rare, and the metal usually had to be traded over very long distances to meet demand in areas which lacked tin deposits.
Gerd Weisgerber was an eminent German professor of mining archaeology. He was one of the first mining archaeologists of the world, who set standards in this scientific discipline. As a scientist from the German Mining Museum, he focused his research mainly on Western Asia, especially on Oman, Jordan, Palestine, and Iran.
Nonferrous archaeometallurgy in the southern Levant is the archaeological study of non-iron-related metal technology in the region of the Southern Levant during the Chalcolithic period and Bronze Age from approximately 4500BC to 1000BC.
Non-ferrous extractive metallurgy is one of the two branches of extractive metallurgy which pertains to the processes of reducing valuable, non-iron metals from ores or raw material. Metals like zinc, copper, lead, aluminium as well as rare and noble metals are of particular interest in this field, while the more common metal, iron, is considered a major impurity. Like ferrous extraction, non-ferrous extraction primarily focuses on the economic optimization of extraction processes in separating qualitatively and quantitatively marketable metals from its impurities (gangue).
Tell Judaidah is an archaeological site in south-eastern Turkey, in the Hatay province. It is one of the largest excavated ancient sites in the Amuq valley, in the plain of Antioch. Settlement at this site ranges from the Neolithic through the Byzantine Period.
Niğde Archaeological Museum is located in the centre of the Turkish provincial capital, Niğde between Dışarı Cami Sokak and Öğretmenler Caddesi. It contains objects found at sites in the surrounding area, including the tell of Köşk Höyük and the Graeco-Roman city of Tyana, both in the nearby town of Kemerhisar.
Değirmentepe or Değirmentepe Hüyük is an archaeological site which is located at 50 km north of the river Euphrates and at 24 km in the northeast of Malatya province in eastern Anatolia. It is now submerged in the reservoir area of the Karakaya and Atatürk dams. Rescue excavations were undertaken in 1978 under the supervision of Ufuk Esin of Istanbul University and interrupted in 1989 by flooding of the dams.
The Vilabouly Complex is an archaeological site that is located in the Savannakhet Province in Laos which holds copper smelting and copper mining during the Iron Age. The Vilabouly Complex is significant since it puts archaeologists in a predicament of when did the origin of bronze metallurgy begin in Southeast Asia. It was estimated that the site was around 400BC - AD 500 as well as 1000 - 400BC reaching both the Iron Age and Bronze Age of Southeast Asia.
