Two crafts of double-layer glass

Nowadays, the double-layer glass is more and more popular. It is not only a tool for drinking water, but it can also be used as a handicraft. So what is its craftsmanship? There are two main types: sandblasting and frosting.

1. Sandblasting process:

This process is very common. It uses sand particles shot by a spray gun at high speed to hit the glass surface of a double-layer glass to form a fine uneven surface, so as to achieve the effect of scattering light and make the light pass through a hazy feeling. The surface feel of the sandblasting process is relatively rough, and because the surface is damaged, the glass bottle that looks originally bright seems to be white glass in the photosensitive. The process difficulty is average.

2. Frosting process:

The frosting of the double-layer glass refers to immersing the glass in a prepared acid liquid (or applying an acid paste), using strong acid to corrode the surface of the glass, and the hydrogen fluoride ammonia 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 double-layer glass is extremely smooth, and the hazy effect is caused by the scattering of crystals.

If the surface is relatively rough, it means that the acid has severely corroded the glass, which is a manifestation of the immature craftsmanship of the frosting master. Or there are some parts that still have no crystals (commonly known as not sanded, or the glass has mottling), but the master’s craftsmanship is not well controlled. This process is technically difficult.

The process is manifested by the appearance of sparkling crystals on the surface of the double-layer glass, which is formed under a critical condition.

I believe you all understand these two processes, and you can choose according to actual needs.
