Go around the museum or luxury stores, and you will find that the display cabinet glass is a bit special. It’s almost non-reflective, good in light transmission, and natural in color. Moreover, compared with regular glass, it seems to be stronger. However, showcase glass did not have so many advantages initially; it has a process of evolution.
Display cabinet glass evolution
Flat Glass Display Cabinet
In the early days, people used regular transparent flat glass and then laminated it to make the glass display cabinet. However, due to the limitations of the production technology of the plate glass itself, the presence of iron elements inside the glass made the glass body greenish. As a result, although it can fully display the exhibits or products, the clarity is average, and the colors distort.
Ultra Clear Glass Showcase
After entering the 20th century, a revolutionary product, the ultra-clear glass comes out. Ultra-clear glass, also known as low iron glass, reduces the iron element to obtain crystal-like transparent effects. Thus, with the application of ultra-clear glass, the second generation of display showcase glass was born.
Low Reflective Glass Display Cabinet
Soon after, the glass industry introduces “low-reflective glass.” It is a result of changing the optical properties of glass itself. Although the ultra-clear glass achieved the effect of being transparent and preventing the color of the exhibits from being distorted, it still failed to solve the reflective properties of the glass itself. Because of the reflections, viewers always see their shadows on the glass. This phenomenon of reflection becomes more evident when taking pictures. The low-reflective glass solves the glass reflection problem, reducing the glass reflectivity from 8% to less than 1%. As a result, it will hardly affect the viewing, making the perfect display glass for museums and luxury products.
Low Reflective Laminated Glass Showcase
Later, the laminated tempered glass appeared to let the showcase glass have the defensive ability. The laminated tempered glass can withstand a certain amount of energy without breaking. Moreover, even if it brokes, it will have the effect of adhesion of the middle layer. Thus, the laminated glass will not fall and hit the exhibits or products. At present, most showcase glass in museums and luxury stores is low reflective laminated tempered glass.
