Copper: the essentials
For example this one http: Also on that one the “yellow” solder is perfectly flat and in new condition. The pot at this link has either never been used or used very little and I’m guessing was made this century.
Copper, that reddish-orange metal that has been used to benefit civilization since B.C. is one of the most important metals used by modern industry.
Water levels would have been high near the time of the final glacier melt enabling human travel along ancient trade routes. Soil conditions indicate that at one time the Wisconsin River was several miles wide in the center part of the state, and the escarpment of Door County as an ancient shoreline proves examples of this. Artifacts from this ancient civilization contribute to understanding the truly wide-ranging influences of early man.
Found at the Oconto site were freshwater clam shells indicative of the Mississippi River and a shell representative of the southern Atlantic coastline. Yet, it is copper for which this culture is known. They fashioned arrowheads and bracelets and other tools and ornaments But copper, like shells, was not native to either Green Bay or Lake Michigan. The only area along the major waterways of North America where copper is found is the Lake Superior region, some of the oldest land on earth.
It yielded vast quantities of copper both in ancient, as well as in modern times.

Physical A copper disc The filled d-shells in these elements contribute little to interatomic interactions, which are dominated by the s-electrons through metallic bonds. Unlike metals with incomplete d-shells, metallic bonds in copper are lacking a covalent character and are relatively weak. This observation explains the low hardness and high ductility of single crystals of copper. For this reason, copper is usually supplied in a fine-grained polycrystalline form, which has greater strength than monocrystalline forms.

Cassiterite ore was then crushed at the surface, washed, and smelted with charcoal in rather small crucibles rather than the large furnaces characteristic of copper smelting sites. Goltepe has yielded many crucibles in which the tin was smelted into a slag that contained globules of pure tin, which had to be separated out by crushing and re-washing.
The small scale of the crucible operations, and the crushing of the slag for multi-stage refining, make it difficult to detect the scale of the operations. For over a decade, archaeologist Tom Levy has been researching the evolution of that Edomite kingdom. According to Genesis, the Edomites, descendents of Jacob’s brother Esau, created a kingdom even before ancient Israel. The remains of Edomite settlements cling to the mountaintops and plateaus high above Petra.
Missing: Prehistoric Michigan’s Half-Billion Pounds of Copper By David Hoffman AA #35 pp Approximately 9, years ago, the Great Lakes achieved their current definition.
VERY rare tapering trapezoidal form vase with cutouts and applied silver. The silver overlay includes the Roycroft orb and cross mark. About 7 inches high. A good example of Roycroft’s use of avant garde European “Secessionist” design elements in their circa copperwork. Thus it is an “important” vase and may be considered the most desirable cataloged Roycroft vase to collectors today.
These are VERY hard to find these days. Here’s another version of the vase above, this time without the silver overlay. This vase is also very rare, and what’s more amazing is that the examplepictured was found by its owner at a barn sale and purchased for only one dollar! We should all be so lucky. This vase has an interesting “double strike” mark that you can see by clicking here Just means the craftsman had to whack it twice — doesn’t add or detract from value.

By becoming familiar with the dozen or so main variations of the Wedgwood mark and by knowing when each was in use, a collector can determine an approximate period of production of an object. A guide to trademarks is listed here and by careful study most collectors can acquire a reasonably sound knowledge. Determining the specific year of production of an item is somewhat more complicated, and this calls for close examination of a variety of other marks, such as three-letter date marks, registration marks, artists signatures or monograms and other devices.
In addition to these, the style and method of production should be kept in mind as giving clues to dating.
Spanish and Portuguese scientists have now introduced a technique for dating artifacts made of copper and bronze.
Natural copper patina at the Nordic Embassies Berlin  The green patina that forms naturally on copper and bronze, sometimes called verdigris , usually consists of varying mixtures of copper chlorides , sulfides , sulfates and carbonates , depending upon environmental conditions such as sulfur-containing acid rain. In industrial and urban air environments containing sulfurous acid rain from coal-fired power plants or industrial processes, the final patina is primarily composed of sulphide or sulphate compounds.
Facade cladding copper cladding ; copper wall cladding with alloys of copper, e. Even a lasting gold colour is possible with copper-alloy cladding, for example Colston Hall in Bristol, or the Novotel at Paddington Central, London. Often, antique and well-used firearms will develop a patina on the steel after the bluing , parkerizing , or other finish has worn. Firearms in this state are generally considered more valuable than ones that have been re-blued or parkerized. The patina protects the firearm from the more damaging rust that would occur were the patina to be polished off.
The process is often called distressing. A wide range of chemicals, both household and commercial, can give a variety of patinas. They are often used by artists as surface embellishments either for color, texture, or both. Patination composition varies with the reacted elements and these will determine the color of the patina.
Within ten years he had enlarged the factory three times, built a china works, taken on the largest and most gifted group of artists in the Potteries, and developed for Doulton a reputation for craftsmanship and artistry still identified with Royal Doulton today. There follows a selection of the backstamps most commonly used on Doulton Burslem wares, and some further hints on dating. The information is taken by permission from “The Doulton Burslem Wares” by Desmond Eyles, a compulsory work of reference for any collector of Doulton wares see back page.
The reference numbers for the Doulton Burslem marks have been prefixed by the letter ‘B’ to distinguish them from those also numbered 1 and up in the list of Lambeth marks given in The Doulton Lambeth Wares. Several of these were adopted after by Doulton and remained in use for about twenty years. The following are two typical examples found on the patterns Rouen and Kew.

Ming Mine Project Overview Rambler Metals and Mining was established to invest in the base metal sector in politically stable jurisdictions. Rambler’s Strategic Vision is the be the leading mine operator and resource developer in Atlantic Canada. First production from the mine began on November 28, from the gold zone. Production from this zone continued up to early May , having produced 14, ounces of gold dore at Nugget Pond mill.
Live ore commissioning of the copper concentrator began on May 14, At the end of fiscal Q1 , Rambler had 6, tonnes of wet copper concentrate stored at their Goodyear’s Cove storage facility, awaiting shipment by Transamine Trading. The company subsequently declared commercial production on 1st November , which was the start of its 2Q reporting period. The Northwestern coast of the island of Newfoundland has a history and culture of gold, base metals and industrial minerals mining dating back to the mid ‘s.
The major centre for the region is the town of Baie Verte, which offers several mining and exploration service providers, deep water loading, hotels, schools, shopping, medical facilities and recreational facilities. The Ming Mine last operated in and produced over 2. Mining ceased when workings reached a neighboring property boundary.
Originally, the term Bronze Age meant that either copper or bronze was being used as the chief hard substance for the manufacture of tools and weapons. In , John Evans recognized that use of copper often preceded the use of bronze, and distinguished between a transitional Copper Age and the Bronze Age proper. He did not include the transitional period in the three-age system of Early, Middle and Late Bronze Age, but placed it outside the tripartite system, at its beginning.
He did not, however, present it as a fourth age but chose to retain the traditional tripartite system. The phrase was never intended to mean that the period was the only one in which both bronze and stone were used. The Copper Age features the use of copper, excluding bronze; moreover, stone continued to be used throughout both the Bronze Age and the Iron Age.

Copper is essential in the formation of normal healthy proteins, that is, normal amino acid sequences, in that it provides a balanced pH state for the blood and tissues. Copper is acidic at a pH of 5. A balanced pH is present in blood type AB, which is the only normal blood type. Consequently, because of generations of poisons, the vast majority of the population has malformed proteins and is missing normal proteins, as can be evidenced just in the blood properties as noted in different “blood types”.
The ” Rhesus Factor ” D-antigen is a malformed or variant A or B protein, resulting from insufficient copper levels. The blood type AB is balanced and therefore does not carry the malformed “Rhesus Factor” protein, thus, only AB negative blood is possible.
