Description
Blattgold. Gegenstand der Erfindung ist ein Blattgold, das aus zwei verschiedenen Goldarten besteht, nämlich aus einer oberen Schicht hochkarätigen und einer unteren Schicht geringer karätigen Goldes.Gold leaf. The invention is a gold leaf, which consists of two consists of different types of gold, namely a top layer of high-quality gold and a lower layer of low karat gold.
Blattgold, das aus zwei verschiedenen Metallschichten besteht, ist allerdings als sogenanntes Zwischgold bekannt, das eine obere Schicht aus Blattgold und eine untere Schicht aus Kupfer oder Silber besitzt. Das Zwischgold ist jedoch nicht dauerhaft, da die Oberschicht aus Blattgold den Luftzutritt zur Unterschicht nicht genügend hindert, so daß diese oxydiert und die Oxydation. durch die Oberschicht hindurch sichtbar wird - Gegenüber dem Zwischgold besteht die Eigenart des Blattgoldes gemäß der Erfindung darin, daß nicht zwei Schichten verschiedener Metalle, sondern zwei Schichten des gleichen Metalls verschiedener Zusammensetzung aufeinanderliegen. Infolgedessen tritt auch die dem Zwischgold als unangenehme Eigenschaft anhaftende Oxydierbarkeit nicht auf. Die Unterschicht aus minderwertigem Gold oxydiert nämlich ebenfalls nicht und kann daher auch nicht -den Hochglanz der Oberschicht stören. Außerdem lassen sich nach dem neuen. Verfahren dünnere Folien schlagen als aus Zwischgoid.Gold leaf, which is made up of two different layers of metal however, known as so-called intermediate gold, which is an upper layer of gold leaf and has a lower layer of copper or silver. The intermediate gold is however not permanent, as the upper layer of gold leaf allows air to enter the lower layer does not hinder enough so that this oxidizes and the oxidation. through the upper class becomes visible through it - Compared to intermediate gold, there is the peculiarity of gold leaf according to the invention in that not two layers of different metals, but two layers of the same metal of different composition lie on top of one another. As a result, the unpleasant property inherent in intermediate gold also occurs Oxidizability does not arise. The lower layer of inferior gold namely oxidizes neither and therefore cannot disrupt the high gloss of the upper class. You can also search for the new. Process thinner foils than from Zwischengoid.
Die Herstellung des ,Blattgoldes gemäß der Erfindung erfolgt z. B. in der Weise, daß man zwei Barren von verschiedenem Goldgehalt auf je einer Fläche schleift, mit den geschliiffenen Flächen aufeinanderlegt und durch Schweißen unter mehrmaligem Glühen innig miteinander verbindet. Dieses Erzeugnis wird, in der üblichen Weise gewalzt, in Quartiere geschnitten und in üblicher Weise in Formen zu Blattgold geschlagen. Die Zusammensetzung der oberen und unteren Goldschicht kann beliebig sein, sofern nur der innige Zusammenhalt beider Schichten gewahrt bleibt. In der Regel wird man die Oberschicht mit höchstens %,8 Dukaten Kupfer legieren dürfen.The production of the, gold leaf according to the invention takes place, for. B. in such a way that two bars of different gold content are placed on one surface each grinds, laid one on top of the other with the ground surfaces and welded underneath repeated glowing intimately connects with each other. This product is, in the usual Rolled in a wise manner, cut into quarters, and in the usual way shaped into gold leaf beaten. The composition of the upper and lower gold layers can be arbitrary as long as the intimate cohesion of both strata is preserved. In the As a rule, one will be allowed to alloy the upper class with a maximum of 8 ducats of copper.
