The art of stained glass as existed since the Antiquity. One of the most famous and ancient usage of copper for artistic glass was done by the Egyptian. The glass craftsmen of Ancient Egypt use copper to give a bright and beautiful green and blue tone to the pieces.
During the 19th and 20th century that copper was added to the work pieces of religious glass art. To obtain a dark red, crimson like effect very high concentrated copper was including in the glass staining process. This process allowed the early Christian glass stained craftsmen to perform their art in order to create the masterpieces of their time.
Nowadays, artisans, artists and craftsmen of stained glass use a different kind of copper to embellish their pieces. Copper foil tape is now applied directly to the glass, allowing artists to get more flexibility in the shape and taint of the material. Indeed, by changing the chemical composition of the alloy, the copper’s color can go from a pale grayish tone to a dark crimson red.

When amateur ‘land fishers’ (or metal detector users) make an archaeological discovery, who receives the proceeds? Should academics get automatic claim upon the find, the owner of the land, or should we follow the childish yet simple rule of finders keepers?
Economists have long claimed that property rights have incentivized innovation and discovery, so to motivate future finds the finders keepers rule should be maintained. However this infringes on the land owners and the much older monarchist rules where from example in ancient Rome, half went to the finder, half to Hadrian. So what have other countries decided?
In the UK, to encourage artifacts to be enjoyed by the public, the Treasure Act of 1996 stipulates if something of worth is discovered, museums or the government will bid or offer the fair market price for them. For example $5.3 million was paid by the successful bid from a British Museum, and split between Herbert and the owner of the Staffordshire field where the Anglo Saxon copper was found.
However in the US, various statues and precedents make the rules murky. For example, US treasure seekers in 1993 discovered the wreckage of a steamer containing millions of dollars worth of gold coins, but had to fight a court battle with both the government and the original insurers of the accident. They eventually won back most of the value, but these decisions are made by case by case and are very much subject to opinion, and muddled by the American culture personified by the ‘no trespasser’ signs.
So which system should prevail? Ultimately, 90% of finds are by amateurs, so without incentivizing them, future discoveries will never see the light of day and be enjoyed for its academic value. But unfortunately as there is a lot of money involved it will inherently be plagued with conflict.
So like the recent Roman copper coin find in the UK, the value of copper can be quite pricey. At Shanghai Metal, we manufacture competitively priced value added copper products. As an ISO 14001 (International Quality Management System) Company and recipient of the “Star Enterprise Award,” Shanghai Metal Corporation prides itself on exceeding international standards of quality and reliability.

If only I had a lot of gold, I would have a bathroom of gold and every day I would use golden toilet paper to wipe my tush. Come on, who really wants to use gold that way? Well apparently there are people who do, because some companies manufacture gold bathrooms and gold toilet paper. People can purchase 22-carat gold toilet paper rolls with US 1.4 million in Dubai. These are not the only weird instances of using gold. The expensive material has made a lot of people crazy.
Some people take really extreme with gold. It’s not necessarily a bad thing. Creative out-of-the-box thinking has made it possible for people to create beautiful gold masterpieces.
The list of unusual gold products is long. Vibrators, iPhones. MacBooks, Legos, Coffee makers, Christmas Trees and so on. There are even golden Porches and Mercedes cars. A golden iPhone 5 is worth of seven normal iPhone 5s.
Even more interesting is that they even make edible objects out of gold. There are gold cheese, ice cream, chocolate and mineral water with gold chips. Do some people actually have so much gold that they can afford to eat it? See the list of original articles to find out more of bizarre gold objects.
In order to find that much gold or even silver, you need a professional rock crushing tool for separating commercially valuable minerals from ores and a vibrating screen from locating them from the crushed rocks. Shanghai Metal Corporation has a long experience in offering excellent mining machinery for businesses worldwide. To know more about our machinery, please visit our website.

“In the fortress which is in the Vale of Achor, forty cubits under the steps entering to the east: a money chest and it [sic] contents, of a weight of seventeen talents.” (First column of the Copper Dead Sea Scroll)
It may sound like one of Indiana Jones plots, but this is real. Found in 1952 in Cave 3 at Khirbet Qumran on the shores of the Dead Sea, Israel, the Copper Scroll is one of the few scrolls among the collection known as the Dead Sea Scrolls to be discovered by archaeologists in the place where it had been overlooked for decades and unread for 2000 years.
The Copper Scroll is made of copper instead of more fragile animal skins. Unlike the other scrolls, it is not a literary work, but the Copper Scroll is a sort of ancient treasure map that lists 64 underground hiding places around Israel that is believed to contain gold and silver treasure, as well as many coins and vessels. It is difficult to assess the value of what is described, since we are not sure what the weights in the scroll are actually equivalent to, but it was estimated in 1960 that the total would top $1,000,000 U.S. Today, the monetary value is close to $3 billion, but the historical value – is priceless.
None of these hoards have been recovered, possibly because the Romans pillaged Judaea during the first century A.D. According to various hypotheses, the treasure never actually existed, that the Copper Scroll is simply a work of fiction. Some believe the scrolls refer to Temple treasure, hidden for safekeeping before the destruction of the Jerusalem Temple in 70 C.E. Others believe the treasure belonged to the sect that lived at Qumran, a sect usually identified with the Essenes, a Jewish group mentioned in the work of the Jewish historian Josephus, who wrote in the 1st century C.E. However, these are just educated guesses. Who the treasure belonged to, and what happened to it, we may never know.
The script has the features which would result from someone writing – a series of random Hebrew and Greek letters – on the copper with a hammer and chisels. “It actually fits the glove perfectly for these people known as the Zealots, who were the priestly group, who were holding down the temple, who were keeping it from the Romans in the best way possible. Before they were massacred, they left things behind in caves here in Qumran”, said Stephen Pfann one of the editors of the Dead Sea Scrolls. Perhaps, as some have theorized, copper was used to better withstand the passage of time. The sheets of bronze are composed of about 99 percent copper and 1 percent tin (approximately 1.5% of the scrolls), which were then joined together.
At the time it was found, however, the document was rolled into two separate scrolls of heavily oxidized copper which was far too brittle to unroll. For five years scholars and experts discussed ways of opening the scroll. Finally, they decided to cut the scroll into sections from the outside using a small saw. Working very carefully they cut the scroll into 23 strips, each one curved into a half-cylinder. Before it was cut, one scholar thought he saw words for silver and gold and suggested that the scroll was a list of buried treasure.
First hand-drawn transcriptions of the Copper Scroll was dated 1960. A new official edition was published in 1962 by the original editor, Józef Milik, also with hand-drawn transcriptions, though the accompanying black-and-white photographs were “virtually illegible”. The scroll was re-photographed in 1988 with greater precision. From 1994 to 1996 extensive conservation efforts by Electricité de France (EDF) included evaluation of corrosion, photography, x-rays, cleaning, making a facsimile and a drawing of the letters.
Portrayed in novels, the Copper Scroll story hit the New York Times bestseller list by author Joel Rosenberg. He b
elieves the second scroll is still out there and it could be the key to the greatest archaeological prize in history. “The Key Scroll has never been found, nobody has any idea where it is.”, said Rosenberg. He adds, “What would be most dramatic is if in fact the treasures that are described by the Copper Scroll -and perhaps revealed more fully in the Key Scroll – are in fact from the second temple. Finding them would in fact be the most dramatic archeological discovery of all time.”. We shall see.
