Near East male figurine, 4500-3500 BC The emergence of
metallurgy may have occurred first in the
Fertile Crescent.
Lead may have been the first
ore that humans
smelted, since it can be easily obtained by heating
galena. Possible early examples of lead smelting, supported by the extreme rarity of native lead, include: lead
beads, found on Level IX of
Chatal/Çatal Hüyük in central
Anatolia, though they might be made of galena,
cerussite, or
metallic lead, and accordingly might or might not be evidence of early smelting; a lead bracelet, found in level XII of
Yarim Tepe I, dated to the 6th millennium BC; a small cone-shaped piece of lead, found in the "Burnt House" in TT6 at
Arpachiyah, dated to the Halaf period or slightly later than the Yarim Tepe bracelet; Archaeological evidence from the village of Una in the eastern Caucasus indicates copper mining activities during the Chalcolithic and Bronze Ages.
Arsenical copper or
bronze was produced in eastern
Turkey (
Malatya Province) at two ancient sites,
Norşuntepe and
Değirmentepe, around 4200 BC. According to Boscher (2016),
hearths or natural draft furnaces,
slag, ore, and
pigment had been recovered throughout these sites. This was in the context of
Ubaid period architectural complexes typical of southern Mesopotamian architecture. Norşuntepe site demonstrates that some form of arsenic alloying was indeed taking place by the 4th millennium BC. Since the slag identified at Norşuntepe contains no arsenic, this means that arsenic in some form was added separately.
Europe A copper axe found at
Prokuplje, Serbia contains the oldest securely dated evidence of copper-making, (7,500 years ago). The find in June 2010 extends the known record of copper smelting by about 800 years, and suggests that copper smelting may have been invented in separate parts of Asia and Europe at that time rather than spreading from a single source. Copper artefacts found in northern Germany and Denmark date from between 4000 and 3300 BC, with most finds dating from 3500 - 3300 BC. They belong to the
Funnel Beaker group. The copper was mined in Serbian mines, as researchers from Kiel have recently discovered.
Ötzi the Iceman, who was found in the
Ötztal Alps in 1991 and whose remains have been dated to about 3300 BC, was found with a
Mondsee copper axe. , Spain Examples of Chalcolithic cultures in Europe include
Vila Nova de São Pedro and
Los Millares on the
Iberian Peninsula. Pottery of the
Beaker people has been found at both sites, dating to several centuries after copper-working began there. The Beaker culture appears to have spread copper and bronze technologies in Europe, along with
Indo-European languages. In Britain, copper was used between the 25th and , but some archaeologists do not recognise a British Chalcolithic because production and use was on a small scale.
South Asia Ceramic similarities between the
Indus Valley Civilisation, southern
Turkmenistan, and northern
Iran during 4300–3300 BC of the Chalcolithic period suggest considerable mobility and trade. The term "Chalcolithic" has also been used in the context of the
South Asian Stone Age. In
Bhirrana, the earliest Indus civilization site, copper
bangles and
arrowheads were found. The inhabitants of
Mehrgarh in present-day
Pakistan fashioned tools with local copper ore between 7000 and 3300 BC. The
Nausharo site was a pottery workshop in the province of
Balochistan, Pakistan, that dates to 4,500 years ago; 12 blades and blade fragments were excavated there. These blades are long, wide, and relatively thin. Archaeological experiments show that these blades were made with a copper indenter and functioned as a potter's tool to trim and shape unfired pottery. Petrographic analysis indicates local pottery manufacturing, but also reveals the existence of a few exotic black-slipped pottery items from the
Indus Valley. In India, Chalcolithic culture flourished in mainly four farming communities –
Ahar or
Banas,
Kayatha,
Malwa, and
Jorwe. These communities had some common traits like painted pottery and use of copper, but they had a distinct ceramic design tradition. Banas culture (2000–1600 BC) had ceramics with red, white, and black design. Kayatha culture (2450–1700 BC) had ceramics painted with brown colored design. Malwa culture (1900–1400 BC) had profusely decorated pottery with red or black colored design. Jorwe culture (1500–900 BC) had ceramics with matte surface and black-on-red design.
Pandu Rajar Dhibi (2000–1600 BC) is a Chalcolithic site in the eastern part of the
Indian subcontinent. It is located on the south bank of
Ajay River in
West Bengal.
Blackware, painted Koshi ware, pottery, various ornaments made of
pearl and copper, various types of tools, pieces of fabric woven from Shimul cotton thread, human and various animal skeletons, burnt clay fragments have been found at the site. In March 2018, archaeologists had discovered three carts and copper artifacts including weapons dating to 1800 BC in
Sanauli village of Uttar Pradesh. The artifacts belongs to
Ochre Coloured Pottery culture.
Americas In the
Archaeology of the Americas, a five-period system is conventionally used which does not include metal ages, though metalworking technology did precede European contact in some areas.
Andean civilizations in South America appear to have
independently invented copper smelting. The term "Chalcolithic" is also applied to American civilizations that already used copper and copper
alloys thousands of years before Europeans immigrated. Besides cultures in the Andes and Mesoamerica, the
Old Copper complex mined and fabricated copper as tools, weapons, and personal ornaments in an area centered in the upper
Great Lakes region (present-day
Michigan and
Wisconsin). The evidence of smelting or alloying that has been found in North America is subject to some dispute and a common assumption by archaeologists is that objects were
cold-worked into shape.
Artifacts from some of these sites have been dated to 6500–1000 BC, making them some of the oldest Chalcolithic sites in the world. Some archaeologists find artifactual and structural evidence of casting by
Hopewellian and
Mississippian peoples to be demonstrated in the archaeological record.
East Asia In the 5th millennium BC copper artifacts start to appear in East Asia, such as in the
Jiangzhai and
Hongshan cultures, but those metal artifacts were not widely used during this early stage. Copper manufacturing gradually appeared in the
Yangshao period (5000–3000 BC).
Jiangzhai is the only site where copper artifacts were found in the
Banpo culture. Archaeologists have found remains of copper metallurgy in various cultures from the late fourth to the early third millennia BC. These include the copper-smelting remains and copper artifacts of the
Hongshan culture (4700–2900) and copper
slag at the Yuanwozhen site. This indicates that inhabitants of the
Yellow River valley had already learned how to make copper artifacts by the later
Yangshao period.
Sub-Saharan Africa In the region of the
Aïr Mountains, Niger, independent copper smelting developed between 3000 and 2500 BC. Their metallurgical technologies would continue to develop into 1500 BC and onward. ==See also==
