The importance and development trend of museum display case glass

With the rapid development of the cultural industry, museums have an increasing need to protect and display cultural relics. As an indispensable part of museums, museum display case glass plays an important role in connecting with audiences and cultural relics. However, how to choose the museum display case glass that meets the display specifications has become a challenge for museum managers.

The importance of museum display cabinet glass is mainly reflected in the following three aspects:

1. Isolation of harmful gases: The museum display case glass needs to have good sealing to prevent harmful gases from entering the cabinet and reacting with cultural relics, causing damage. For example, the reaction between hydrogen sulphide and pigment will to the discolouration of paintings, and the reaction between chlorine and fibre will to the deterioration of textiles. Therefore, the precision of the size of the display cabinet glass is crucial.

2. Facilitate temperature and humidity control: the dimensional accuracy of museum display case glass helps to achieve precise control of temperature and humidity inside the cabinet. Relative humidity is an important factor affecting the integrity of cultural relics, too high or too low relative humidity will cause damage to cultural relics. Only the exhibition cabinet and the exhibition cabinet glass are seamless, to form a stable cabinet environment, for constant temperature and humidity systems to play a role in providing favourable conditions.

3. Blocking harmful light: museum display case glass needs to effectively block ultraviolet light because ultraviolet light is a destructive invisible light. Ultraviolet light can cause dyes to fade and cause irreversible damage to textiles, ancient paintings and other cultural relics. Modern museum display case glass blocks 99.9% of UV rays, essentially preventing them from damaging artefacts.

With the upgrading and development of museums, the requirements for display case glass have also increased. Initially, the museum's requirements for display case glass were relatively simple, only requiring the glass to be transparent. However, ordinary glass is prone to breakage and theft and cannot meet the needs of protecting cultural relics. Toughened glass was introduced as a kind of high-strength glass, but its shortcomings, such as self-breaking and mottling, gradually faded out of the field of museum display cabinets.

With the progress of science and technology, low reflection glass has become the new trend in museum display case glass. Low-reflective glass has extremely low reflectivity and good light transmittance, which eliminates the interference between the audience and the artefacts and makes the viewing of artefacts clearer. At the same time, low-reflective glass has a low rate of colour deviation, which can show the real colour and lustre of cultural relics. In addition, low-reflection glass can effectively block ultraviolet rays, and the design of double-layer laminated glass improves safety.

In summary, museum display case glass has an important role in the process of protecting cultural relics and displaying them in museums. With the development of science and technology, the museum's requirements for display case glass continue to improve, and low-reflective glass has become a new development trend, providing better conditions for the protection and display of cultural relics.
