History

The word copper derives from the Latin Cuprum. It is a reddish transition material that presents high thermoelectric conductivity, reason for which it becomes perfect for using in kitchenware. This way you can save time and energy. 

Let's get to know a little of its history. 

Native copper (in its natural form) must have been the first metal ever used by men. History tells us that it's have been used since over 10000 years ago, and as evidence of that we have a copper pendant found in Iraq that dated from 8700 BC. 

It is assumed that the development of metallurgy's history has followed this order:

Cold Working 

The copper in its natural form is shaped at ambient

Annealing

Copper is submitted to a heat treatment until it turns red. Then it is left to cool at ambient temperature. This increases its malleability, which makes it easier to work with;

Smelting

Copper and brass are melted and mixed in the right proportions, originating bronze;

Lost Wax Method 

A wax sculpture is elaborated and then placed inside a box/hole, which is filled with cast. However, a space is left between the wax sculpture and the box/hole. That mold is heated until the wax evaporates, leaving the cast mold of the sculpture. The melted copper is poured into the mold and once it has cooled the mold is broken and the copper sculpture ready.

During the Neolithic Period (7500 BC) this four methods coexisted, in the southeastern of Anatolia. As agriculture was independently developed in many distinct Countries (China, Paquistan, etc.), so did copper's fusion: in China before 2800 BC; in Central America in 600 a.C.; in western Africa in the XIX/XX century a.C..

In Italy, on 1991, the Ice Man was found. The statue had 5300 years old and it incorporated a copper axe with 99.7% of purity. 

Sumerian coins, guns, pipes, and even household items were found, from 3000 BC. 

In Egypt, copper was used in wound sterilization and as a vessel for drinking water, since it was considered to be a clean material.  The methods for obtaining bronze were perfected due to the discovery that adding small amounts of brass facilitates copper's fusion. This metal, due to its resistance, was represented by the Ankh, eternal life's symbol. 

Since 2000 BC that copper was used in ancient China and since 1200 BC that high quality bronzes are manufactured. 

Phoenicians started by importing copper from Greece, and then exploring the available mines in their territory. 

In Cyprus, considered by a long time as the country of copper by excellence, this metal was represented with the same symbol of Venus (Greek Aphrodite), the goddess of beauty. The mirrors were, for that reason, manufactured in copper. 

From the 6th to the 3rd century BC Romans used copper to manufacture coins: the Emperor Julio Caesar had his face printed in the currency used at the time. 

In ancient India copper was used by the holistic medicine (Ayurveda) in the manufacturing of surgical instruments and other medical equipment. 

The gates of the Jerusalem Temple contained Corinthian bronze. 

Even the Christian Bible mentions the use of copper: "There is a mine for silver and a place where gold is refined; Iron is taken from the earth, and copper is smelted from ore" (Job 28:1-2). 

King Salomon's Temple, in Timna (Israel) had, amongst other objects, cast bronze columns, with 5m diameter and 8m height, accordingly to biblical references (1st Book of Kings 7:13-50). Beside the columns, there were also two bronze capitols with 2.5m height and "The Ocean": a bronze water tank with the capacity of 80.000L, held by 12 bronze bulls. 

Along with the Dead Sea Scrolls (approximately from the II Century BC) a bronze roll was found in Qumran, in the year of 1952, that had to be opened very carefully because the oxidizes metal made its opening hard and could cause it to break in the middle. This roll was a treasure map that lead the way, supposedly, to multiple and hidden wealth, such as gold and silver. However, the treasures were never found. 

It is assumed that copper kitchenware was initially created over 3000 years ago. Copper, formerly, had to be hammered by hand until the ideal thickness was achieved. For that reason, the utensils manufactured at the time were made of extremely thick copper sheets. 

The Bagdad battery, from 248 BC contained copper cylinders welded with lead, which made it look like a galvanic cell. This lead to believe that it was the first battery ever invented. 

The Great Mountain of Copper was a mine in Falun, Sweden, which stayed active from 800 BC to 1992. Here 2/3 of European copper necessities in the 17th century were extracted here, which caused many wars inside de country. Even the currency was made of copper back then. 

However, the usage of copper wasn't restricted to coins. It was also used by Renaissance sculptors in the construction of the famous Statue of Liberty (1886).

With the Industrial Revolution, the laminating machine (used since 1495 by Da Vinci) was perfected, which allowed the obtaining of thinner copper sheets in larger amounts, which caused a raise on kitchenware production.  

The usage of copper sheets in ship hulls also increased, spreading to numerous countries.
