Description

Spiegelmirrors

Es sind Spiegel bekannt, denen Glas einen Gehalt an Kobaltoxyd, Kupferoxyd, Nickeloxyd und Chromoxyd aufweist und die <lie Eigenschaft haben, die Färbung· der Bilder, welche sie zurückwerfen, zu verändern, indem man beispielsweise den Bildern der durch das künstliche Licht beleuchteten Gegenstände eine Färbung gibt, die sich, der Färbung derselben Gegenstände, die mit natürlichem Licht beleuchtet sind, nähert.Mirrors are known to have a glass Content of cobalt oxide, copper oxide, nickel oxide and chromium oxide and the <lie Have the ability to change the coloring · of the images which they reflect by for example, the images of the objects illuminated by the artificial light a coloring gives itself, the coloring of the same objects with natural light are lit, is approaching.

'Man weiß anderseits, daß die mit Neodymoxyd gefärbten Gläser die Eigenschaft besitzen, die gelben Strahlen des Spektrums zu absorbieren und infolgedessen die Durchsichtigkeit unter gewissen Beleuchtungsbedingungen, insbesondere bei dunklem oder nebligem Wetter, zu verbessern.'On the other hand, it is known that glasses colored with neodymium oxide have the property to absorb the yellow rays of the spectrum and, consequently, the transparency under certain lighting conditions, especially in dark or foggy weather.

Die Erfindung betrifft einen Spiegel, der sich durch die Anwendung von Neodymoxyd als Bestandteil des verspiegelten Glases kennzeichnet, was insbesondere den Vorteil hat, dem Gesicht eine wärmere und demgemäß schmeichelhaftere Färbung zu geben, indem gleichzeitig die Klarheit der Züge erhöht wird, während die Färbung des Gesichtes, die durch Vergleich in leinem gewöhnlichen Spiegel und in einem Spiegel, dessen Glas Kobalt- und Kupferoxyd enthält, beobachtet wird, im ersteren Fall. gelber und im zweiten Fall bläulicher ist.The invention relates to a mirror that is created by the use of neodymium oxide as part of the mirrored glass, which has the particular advantage of to give the face a warmer and accordingly more flattering color by at the same time the clarity of the features is increased, while the coloring of the face which is caused by Comparison in an ordinary mirror and in a mirror whose glass is cobalt and Contains copper oxide, is observed in the former case. yellow and in the second case is bluish.

Das zur Herstellung eines Spiegels gemäß der Erfindung verwendete Glas muß Neodymoxyd in solchem Verhältnis enthalten, daß der Spiegel sich beim ersten Blick nicht von gewöhnlichen Spiegehi unterscheidet. Die Vesrhältnismengen ändern sich mit der Dicke des Spiegels und mit den Bedingungen für seine Vierwendung, überschreiten aber nicht 1 0/0 für ein Glas von 3 mm Dicke und 0,5 o/o für ein Glas von 6 mm Dicke.The glass used to manufacture a mirror according to the invention must contain neodymium oxide in such a ratio that the mirror does not differ from ordinary mirror at first glance. The Vesrhältnismengen vary with the thickness of the mirror and the conditions for its four-turn, but do not exceed 1 0/0 mm for a glass thickness of 3 and 0.5 o / o mm for a glass thickness of 6.
