Today one can often come across such a mysterious term as "museum glass". It is increasingly being used in various fields of application, as it has characteristics that distinguish museum glass from ordinary glass. What are the advantages of this new product and how to work with it correctly?
All about museum glass
Glass 2 millimeters thick is called museum or non-glare glass, which has been processed using magnetron sputtering, which gives it unique optical characteristics. This process is quite expensive, therefore the raw material is high quality glass with a low iron content. Multi-layer deposition of metal ions covers the glass with an invisible film that dampens the light wave. As a result, the incident light stream is not reflected, but passes through the glass.
Museum discolored glass, in contrast to standard glass, has a white cut on the cut.
The light transmission of museum glass is about 99%, while that of ordinary glass is 90%. The specularity of the non-glare glass is reduced to 1%, making it virtually invisible to the eye. In addition, thanks to magnetron sputtering, the image on the museum glass is protected from damaging ultraviolet rays. Unlike museum glass, the popular anti-reflective glass produces a similar effect due to the rough surface that scatters incident light rays. At the same time, the light transmission of the glass is significantly reduced, it acquires a dullness, which limits the scope of its application.
Working with museum glass
Unlike anti-reflective glass, museum glass extinguishes the flow of light and at the same time blocks ultraviolet rays. At the same time, the degree of its light transmission increases significantly, as a result of which it is ideal for protecting a wide variety of images. When working with museum glass, it is cut and processed in the same way as ordinary glass - however, there are some nuances here. Museum glass has a double-sided magnetron coating, which, despite its hardness, can be scratched.
Scratches on non-reflective glass are much more noticeable than similar defects on the surface of standard glass.
To avoid damage, the workplace must be cleaned of small glass fragments before working with museum glass and wear gloves so as not to leave fingerprints on it. Museum glass can only be wiped with neutral pH solutions and soft, lint-free cloths - the use of abrasive detergents for this purpose is prohibited. Non-reflective glass is used not only for storing images - it is also used in professional camera lenses.
