Difference between frosted and sandblasted glass wine bottles

Glass bottle frosting and sandblasting are both hazy treatment on the surface of the glass bottle, so that the light can form a relatively uniform scattering after passing through the lampshade, and it is difficult for ordinary users to distinguish between these two processes. The following describes the production methods of the two processes and how to identify them.

1. Frosting process: Frosting refers to immersing the glass bottle in the prepared acidic liquid (or applying acid-containing paste) to erode the glass surface with strong acid, and at the same time, the ammonia hydrogen fluoride in the strong acid solution causes the glass surface to form crystals. Therefore, if the frosting process is done well, the surface of the frosted glass is extremely smooth, and the hazy effect is produced by the scattering of crystals. If the surface is relatively rough, it means that the acid has serious erosion on the glass, which is a manifestation of the immature craftsmanship of the frosting master. Or some parts still have no crystals (commonly known as not ground to sand, or the glass has mottled), which also belongs to the poor control of the master craftsmanship. This process is technically difficult. The process is best characterized by the appearance of sparkling crystals on the glass surface, which are formed under a critical condition, mainly because the ammonium hydrogen fluoride has reached a point where it is running out of sales.

2. Sandblasting process: This process is very common. It hits the surface of the glass with sand particles shot at a high speed from a spray gun, so that the glass forms a fine concave and convex surface, so as to achieve the effect of scattering light, making the light appear hazy when it passes through. The surface of the glass product by sandblasting process is relatively rough. Because the glass surface is damaged, it seems that the original clear glass wine bottle appears to be white glass. The craftsmanship is generally difficult.

The two processes are completely different processes. The cost of frosted glass is higher than that of sandblasted glass, and the effect is mainly due to the needs of users. Some unique glasses are also not suitable for frosting. From the point of pursuit of nobility, frosted should be used. The sandblasting process can be completed in general factories, but it is not easy to do the sandblasting process well.
