Copper Scroll

Shiny, reddish copper was the first metal manipulated by humans, and it remains an important metal in industry today. About three-quarters of that copper goes to make electrical wires, telecommunication cables and electronics. Aside from gold, copper is the only metal on the periodic table whose coloring isn’t naturally silver or gray. Most copper occurs in ores and must be smelted, or extracted from its ore, for purity before it can be used. Humans have been making things from copper for at least 8, years and figured out how to smelt the metal by about B. The next technological leap was creating copper alloys by adding tin to copper, which created a harder metal than its individual parts: bronze. The technological development ushered in the Bronze Age, a period covering approximately to B. C, and isdistinguished by the use of bronze tools and weapons, according to History. Copper artifacts are sprinkled throughout the historical record.

The Copper Scroll. Found in a cave near the Dead Sea, the Copper Scroll describes a vast treasure—hidden in locations throughout the Judean wilderness. Some think the scroll served as a map to the treasure from the Jerusalem Temple. Made of copper, the scroll stood apart from the rest of the Dead Sea Scrolls , which were composed of parchment or papyrus.

On this page you will find more information on how copper pans are made, how to tell the different techniques involved in manufacture apart and how these contribute to the quality of the pan. For more information on cooking with copper and the need for a proper tin lining before doing so, please visit our FAQs. All early copper vessels were created by hammering the copper into the desired shape. It required great skill and many years of practice in order to deliver perfectly proportioned products and kitchenware created by this method remains the most desirable.

An added benefit of the hammering was that once the surface had been perfectly smoothed out, the metal retained the imprint of hammer blows, giving a kaleidoscopic reflection. As the industrial revolution progressed towards the end of the 19th century, this hand-made production process was gradually replaced by more mechanized techniques. The copper would be rolled into sheets, producing a much smoother finish, unfortunately without the multi-varied reflection.

As these techniques were perfected, the copper sheets became ever thinner, as a way to reduce costs. The difference is quite striking when comparing a modern copper pan with a 19th century hand-made one, which can often be a factor 3 or 4 heavier due to the thickness of the copper. Given that most kitchenware is cilindrical in some shape or form, joints are required to bring the separate pieces of copper together.

There are many different ways of doing this, but one of the most common ones for hand-made copper pans is called dovetailing. The coppersmith would hammer the edges of the different pieces to about half their original thickness and then cut slits in the metal, thereby producing small strips of copper that could be interwoven and hammered back together. Clean dovetailing is a sign of quality handwork primarily found in pres copperware as the skill and cost involved in creating joints this way led to its disappearance.

Researchers from Binghamton University, State University at New York, have found a copper band that indicates ancient Native Americans engaged in extensive trade networks spanning far greater distances than what has been previously thought. According to an announcement on the University web site , the team discovered a copper band, alongside the cremated remains, at a burial site in coastal Georgia. Radiometric dating using an accelerated mass spectrometer indicate that the remains and band are both more than 3, years old.

This is significant, as it pushes the practice of cremation, as well as the use of copper, in the region more than a millennium older than previously thought. According to the U. The emergence of copper tools is credited for helping mankind transition out of the Stone Age at about B. The period that followed is sometimes known as the Copper Age, or the Chalcolithic Age. The discovery that alloying copper with tin produces bronze launched the Bronze Age at about B.

Copper has continued to be an extremely useful metal throughout history thanks to its high thermal and electrical conductivity. Another reason why copper is so widely used is the fact that it can be recycled indefinitely without losing any of its chemical or physical properties. Recycled, or secondary, copper is indistinguishable from primary copper, and the production process consumes much less energy.

Here, a fuller set of 71 dates from 53 graves is presented. We identify a small reservoir effect in a number of individuals based on 14C, as well as carbon and nitrogen stable isotopes. We test the effect of this by building a series of different Bayesian models.

Historians identify the king of Egypt as Akhenaten, but who was writing to him? And where was Alashiya? Many historians feel that the most likely candidate for copper-rich Alashiya is in Cyprus. But the story of identifying the lost city near the modern-day Cypriot village of Enkomi is filled with archaeological blunders and near misses.

It is now known that during the Late Bronze Age, from the 15th to 11th centuries B. Unlike the nearby ancient city of Salamis whose Roman ruins stand to this day not to be confused with the Island of Salamis just west of Athens , few traces of the ancient site now known as Enkomi remained.
