The use of hallmarks, at first on silver, has a long history dating back to the 4th century AD—there is evidence of silver bars marked under authority of the Emperor Augustinian [ clarification needed ] around AD —and represents the oldest known form of consumer protection.
A series or system of five marks has been found on Byzantine silver dating from this period, though their interpretation is still not completely resolved.
From the Late Middle Ages , hallmarking was administered by local governments through authorized assayers. These assayers examined precious metal objects, under the auspices of the state, before the object could be offered for public sale.
The Master Craftsman was responsible for the quality of the work that left his atelier or workshop, regardless of who made the item. Hallmarking is Europe's earliest form of consumer protection.
A standard for silver was thus established. In , King Philip III prescribed, by royal decree, the mark for use on silver works, along with specific punches for each community's smiths.
In , his successor, Philippe IV "the Fair" expanded the use of hallmarks to gold works. In King Edward I of England enacted a statute requiring that all silver articles must meet the sterling silver standard This entity was headquartered in London at Goldsmiths' Hall , from whence the English term "hallmark" is derived.
In , the French cardinal Jean de Brogny , after consulting a council of eight Master Goldsmiths from Geneva , enacted a regulation on the purity and hallmarking of silver objects following the French standards for application in Geneva.
In the modern world, in an attempt at standardizing the legislation on the inspection of precious metals and to facilitate international trade, in November a core group of European nations signed the Vienna Convention on the Control of the Fineness and the Hallmarking of Precious Metal Objects.
The multi-tiered motif of the CCM is the balance scales, superimposed, for gold, on two intersecting circles; for platinum, a diamond shape and for silver a mark in the shape of the Latin letter "M".
Other nations monitor the activities of the Convention and may apply for membership. Complete international hallmarking has been plagued by difficulties, because even amongst countries which have implemented hallmarking, standards and enforcement vary considerably, making it difficult for one country to accept another's hallmarking as equivalent to its own.
While some countries permit a variance from the marked fineness of up to 10 parts per thousand, others do not permit any variance known as negative tolerance at all.
Similarly, with the consent of all the current member states, the terms of the convention may be amended. The most significant item currently up for debate is the recognition of palladium as a precious metal.
Some member nations recognize palladium as a precious metal while others do not. Hallmarks for gold, palladium, platinum and silver from Poland.
Official Polish hallmarks between and French mark head of horse for jewellery and watches from 18k gold made in the French provinces between and The Hallmarking Act made Britain a member of the Vienna Convention as well as introducing marking for platinum, a recognised metal under the Convention.
All four remaining assay offices finally adopted the same date letter sequences. In changes were made to the UK hallmarking system to bring the system closer into line with the European Union EU.
Note: that under this latest enactment, the date letter is no longer a compulsory part of the hallmark.
It is likely that an 'offshore' assay mark will have to be added to signify that the item was not assayed in the UK. As it now stands, the compulsory part of the UK hallmark consists of the sponsor or maker's mark, the assay office mark, and the standard of fineness in this case silver, parts in These are shown in the top of the two example hallmarks.
The bottom example shows the extra marks that can also be struck, the lion passant, indicating Sterling silver, the date mark lowercase a for '' , and in this example, the 'Millennium mark', which was only available for the years and The bottom example bears the Yorkshire rose mark for the Sheffield Assay Office.
The Hallmarking Act was amended in July to include palladium from January Although hallmarking in the Swiss territories dates back to Geneva in the fifteenth century, there was no uniform system of hallmarking in Switzerland until Before that time, hallmarking was undertaken at the local level by the Swiss cantons.
With the introduction of Federal hallmarking laws starting in , increased uniformity was established. Under the current law, on all gold, silver, platinum or palladium watches cases made in Switzerland or imported into Switzerland, there shall be affixed,  near the Maker's Responsibility Mark and his indication of purity, the official Hallmark, the head of a Saint Bernard dog.
Only precious metal watch cases must be hallmarked. Swiss hallmarking for other articles such as jewelry and cutlery is optional. In addition to the Swiss hallmark, all precious metal goods may be stamped with the Common Control Mark of the Vienna Convention.
The Netherlands, who are members of the International hallmarking Convention, have been striking hallmarks since at least Like many other nations, the Netherlands require the registration and use of Responsibility Marks, however, perhaps somewhat unusual, there is a book published entitled "Netherlands' Responsibility Marks since " in three volumes and in the English language illustrating all the responsibility marks registered there since that time.
This is significant since producers that exported precious metal goods to the Netherlands would have been required to register their marks.
The Netherlands' hallmarks are also recognized in Belgium, Denmark, Finland and Sweden, which have voluntary hallmarking systems. One of the two Dutch assay offices, WaarborgHolland b.
The other one is located in Joure, called Edelmetaal Waarborg Nederland b. The Netherlands recognises platinum, gold, silver and palladium as precious metals.
Traditionally, the hallmarks are "struck" using steel punches. Punches are made in different sizes, suitable for tiny pieces of jewelry to large silver platters.
Punches are made in straight shank or ring shank, the latter used to mark rings. The problem with traditional punching is that the process of punching displaces metal, causing some distortion of the article being marked.
This means that re-finishing of the article is required after hallmarking. For this reason, and that off-cuts from sprues are often used for assay, many articles are sent unfinished to the assay office for assay and hallmarking.
A new method of marking using lasers is now available, which is especially valuable for delicate items and hollowware , which would be damaged or distorted by the punching process.
Laser marking also means that finished articles do not need to be re-finished. Laser marking works by using high-power lasers to evaporate material from the metal surface.
Two methods exist: 2D and 3D laser marking. Precious metal items of art or jewelry are frequently hallmarked depending upon the requirements of the laws of either the place of manufacture or the place of import.
Where required to be hallmarked, semi-finished precious metal items of art or jewelry pass through the official testing channels where they are analyzed or assayed for precious metal content.
While different nations permit a variety of legally acceptable finenesses, the assayer is actually testing to determine that the fineness of the product conforms with the statement or claim of fineness that the maker has claimed usually by stamping a number such as for 18k gold on the item.
In the past the assay was conducted by using the touchstone method but currently most often it is done using X-ray Fluorescence XRF.
XRF is used because this method is more exacting than the touchstone test. The most exact method of assay is known as fire assay or cupellation.
This method is better suited for the assay of bullion and gold stocks rather than works or art or jewelry because it is a completely destructive method.
The age-old touchstone method is particularly suited to the testing of very valuable pieces, for which sampling by destructive means, such as scraping, cutting or drilling is unacceptable.
A rubbing of the item is made on a special stone, treated with acids and the resulting color compared to references.
Differences in precious metal content as small as 10 to 20 parts per thousand can often be established with confidence by the test.
It is not indicated for use with white gold, for example, since the color variation among white gold alloys is almost imperceptible.
The modern X-ray fluorescence is also a non-destructive technique that is suitable for normal assaying requirements.
It typically has an accuracy of 2—5 parts per thousand and is well-suited to the relatively flat and large surfaces.
It is a quick technique taking about three minutes, and the results can be automatically printed out by the computer. An expanding tumour requires new blood vessels to deliver adequate oxygen to the cancer cells, and thus exploits these normal physiological processes for its benefit.
To do this, the cancer cells acquire the ability to orchestrate production of new vasculature by activating the 'angiogenic switch'.
In doing so, they control non-cancerous cells that are present in the tumor that can form blood vessels by reducing the production of factors that inhibit blood vessel production, and increasing the production of factors that promote blood vessel formation.
One of the most well known properties of cancer cells is their ability to invade neighboring tissues. It is what dictates whether the tumor is benign or malignant, and is the property which enables their dissemination around the body.
The cancer cells have to undergo a multitude of changes in order for them to acquire the ability to metastasize, in a multistep process that starts with local invasion of the cells into the surrounding tissues.
They then have to invade blood vessels, survive in the harsh environment of the circulatory system, exit this system and then start dividing in the new tissue.
In his NCRI conference talk, Hanahan proposed two new emerging hallmarks and two emerging characteristics. These were later codified in an updated review article entitled "Hallmarks of cancer: the next generation.
Most cancer cells use alternative metabolic pathways to generate energy, a fact appreciated since the early twentieth century with the postulation of the Warburg hypothesis ,   but only now gaining renewed research interest.
Instead of completely oxidizing glucose to produce as much ATP as possible, cancer cells would rather convert pyruvate into the building blocks for more cells.
Mitochondrial membrane potential is hyperpolarized to prevent voltage-sensitive permeability transition pores PTP from triggering of apoptosis.
The ketogenic diet is being investigated as an adjuvant therapy for some cancers,    including glioma,   because of cancer's inefficiency in metabolizing ketone bodies.
Despite cancer cells causing increased inflammation and angiogenesis, they also appear to be able to avoid interaction with the body's immune system via a loss of interleukin immune system.
See cancer immunology. The updated paper also identified two emerging characteristics. These are labeled as such since their acquisition leads to the development of the hypothesized "hallmarks".
Cancer cells generally have severe chromosomal abnormalities which worsen as the disease progresses. HeLa cells , for example, are extremely prolific and have tetraploidy 12, trisomy 6, 8, and 17, and a modal chromosome number of 82 rather than the normal diploid number of See genome instability.
Recent discoveries have highlighted the role of local chronic inflammation in inducing many types of cancer. Inflammation leads to angiogenesis and more of an immune response.
The degradation of extracellular matrix necessary to form new blood vessels increases the odds of metastasis. See inflammation in cancer.
An article in Nature Reviews Cancer in pointed out that five of the 'hallmarks' were also characteristic of benign tumours. An article in the Journal of Biosciences in argued that original data for most of these hallmarks is lacking.

The only hallmark of malignant disease was its ability to invade and metastasize. An article in the Journal of Biosciences in argued that original data for most of these hallmarks is lacking. It argued that cancer is a tissue-level disease and these cellular-level hallmarks are misleading. Notes and references. In a law was enacted making the minimum national standard for silver in Germany. In the use of individual city marks was abolished and replaced by the national mark (reichsmark) of a crescent moon & crown mark (Halbmond und Krone) representing the entire German state.
