In order to obtain the best products during production, glass bottle manufacturers control the process very strictly. So what aspects should be checked when accepting glass alcohol bottles?
First of all, the quality of the frit should be pure: if the frit is impure, there will be lines, bubbles or sand on the glass drinkware. The rough lines can be felt by hand, but the fine lines can only be seen by facing the light. The material bubble lives in a relatively deep part of the vitreous body and looks like a small circle from the outside. “Sand” refers to the white granular silica sand embedded in the vitreous body without melting, and also refers to other granular impurities.
Secondly, the thickness of the same batch of glass alcohol bottles should be the same: when selecting, observe the glass bottles against the light. If the light perception is the same everywhere, it means that the thickness is the same. From the outside, the bottom should be level, not sloped or pot-like; flicking the walls with your fingers should make a nice sound.
The appearance of the final glass alcohol bottles should be beautiful: that is, the surface should be smooth; the gloss of the bottle should be good; the geometric shape should be smooth; the bottle cap should not be too loose or too tight, and the shape of the neck should be coordinated.
they must also strictly select the finished glass bottles. Vlaliant has been established for 8 years with state-of-the-art production technology and is an excellent choice.
