Actually, it is true that the Berlin Iron jewelry evolved from an existing handicraft and it is not hard to see where it was. In the seventeenth and eighteenth centuries was begun produced significant quantities of iron plaques, medallions, settlement, and mirror frames start made as well as ornaments carved and engraved iron, and pictures in relief of cast iron. Examples of these objects have been seen in the Le Secq des Tourelles museum in Rouen and show great skill and a considerable sense for the special quality of the material. It is very likely that this type of work was carried out by gunsmiths when their traditional trade in creating helmets, shields and armor extensive became obsolete. One can reasonably assume that a number of famous - arms-producing centers of Europe tried their skills will keep on the card. The first factory in Berlin that iron jewelry was opened in 1804 on the grounds behind the charity and became known as the Royal Berlin plant. But since that time, these iron ornaments were known under the name of the Prussian capital. But since that time, these iron jewelry familiar with the name of the Prussian capital, and production was apparently originated at Gleiwitz in Silesia, and similar work, it is said was also done in France already in 1789, during the outbreak of Revolution. The Royal Berlin Factory was obviously busy making all kinds of iron goods and jewelry have it a little have been part of. A good example is the iron bridge in the park of Charlottenburg (Berlin). But because there is no indication that this kind of work was carried out in Silesia for the move to Berlin, the neo-classical design of some parts of Berlin iron may be from earlier years than 1804 - even it is possible that they did 20 years were made before, but it is also possible, and more probably about 6 or 8 years later. Anyway, there is no certainty and even some confusion about the earliest production even in Berlin since 1806, when the factory went into production less than two years earlier when Napoleon occupied the city, the molds were taken to France, and it is generally accepted that the production was resumed. If this was indeed so should there have been a number of different stages of production that no longer can be distinguished: Silesia for 1804, Berlin from 1804 to 1806, France 1806 -; Berlin after 1806. It is very likely that the early work, after the fall of Napoleon in 1815, everybody had sniffed the French culture and taste, and we are probably not far wrong if we assume that all the Berlin iron, consisting of classical pseudocameeën, eagles, and other course designs have a classical origin and that they can be dated from before the Battle of Waterloo.
