Chalcolithic

The archaeological site of Belovode, on Rudnik mountain in Serbia, has the world's oldest securely dated evidence of copper smelting at high temperature, from c. 5,000 BC.

Ancient writers, who provided the essential cultural references for educated people during the 19th century, used the same name for both copper- and bronze-using ages.

[6] Subsequently, British scholars used either Evans's "Copper Age" or the term "Eneolithic" (or Æneolithic), a translation of Chierici's eneo-litica.

After several years, a number of complaints appeared in the literature that "Eneolithic" seemed to the untrained eye to be produced from e-neolithic, "outside the Neolithic", clearly not a definitive characterization of the Copper Age.

The process of transition from Neolithic to Chalcolithic in the Middle East is characterized in archaeological stone tool assemblages by a decline in high quality raw material procurement and use.

Here, analysis of six archaeological sites determined a marked downward trend in not only material quality, but also in aesthetic variation in the lithic artefacts.

[14] The Tehran Plain findings illustrate the effects of the introduction of copper working technologies on the in-place systems of lithic craft specialists and raw materials.

[14] Arsenical copper or bronze was produced in eastern Turkey (Malatya Province) at two ancient sites, Norşuntepe and Değirmentepe, around 4200 BC.

[15] A copper axe found at Prokuplje, Serbia contains the oldest securely dated evidence of copper-making, c. 5500 BC (7,500 years ago).

Examples of Chalcolithic cultures in Europe include Vila Nova de São Pedro and Los Millares on the Iberian Peninsula.

[21] In Britain, copper was used between the 25th and 22nd centuries BC, but some archaeologists do not recognise a British Chalcolithic because production and use was on a small scale.

[22] 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.

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.

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.

[29] In March 2018, archaeologists had discovered three carts and copper artifacts including weapons dating to 1800 BC in Sanauli village of Uttar Pradesh.

[30] 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.

[32] 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.

[33] Some archaeologists find artifactual and structural evidence of casting by Hopewellian and Mississippian peoples to be demonstrated in the archaeological record.

Archaeologists have found remains of copper metallurgy in various cultures from the late fourth to the early third millennia BC.
