The so-called patterned glass is a pattern with slight bumps on the surface of the glass. The production of patterned glass is quite like textile printing. When the glass melt is in a softened state, let it pass through a pair of embossing rollers, so the pattern on the rollers is "printed" on the glass melt. The "printed" patterned glass melt is then processed in the subsequent process to become the embossed glass that people need.
Although the glass surface has a strong three-dimensional pattern, its transparency is better: when light passes through the patterned glass, it will diffuse and deform the image of the objects inside. People stand at different distances from the patterned glass to observe the room, and the images of objects that can be seen are also different. As the distance between it and the patterned glass becomes longer, the image of the object seen from the outside of the room becomes more and more blurred. In addition, due to the different patterns of the embossed glass, the images of the objects that pass through will also be different. It is precise because of this characteristic that patterned glass is used to make window glass, which will not affect the indoor lighting effect, but also make it impossible for people outside to see the indoor situation.
