How to distinguish the quality of a glass wine bottle?

Glass has excellent performance and can be applied in various occasions. In terms of interior decoration, painted glass and hot-melt glass can be used, with diverse styles; Suitable for using safety glass such as tempered glass and laminated glass in situations where personal safety needs to be protected; When adjusting brightness and protecting privacy, frosted glass and dimming glass can be used for convenience and durability. To understand the main process of glass bottle production and how to distinguish the quality of glass wine bottles, please refer to the following text.

1. Inspection of glass sheets
The appearance quality mainly involves checking the flatness, observing for quality defects such as bubbles, inclusions, scratches, lines, and fog spots. Glass with such defects will deform during use, reducing its transparency, mechanical strength, and thermal stability. It is not suitable for engineering use. Due to the fact that glass is a transparent object, its quality can be easily distinguished through visual inspection during selection. The inspection of glass processing products should not only be carried out according to the requirements of flat glass, but also to check the processing quality, whether the specifications and dimensions are standard, whether the processing accuracy and pattern clarity meet the requirements, and at the same time, no defects are allowed on the edges. The appearance quality of hollow glass bricks shall not have cracks, opaque unmelted substances are not allowed in the glass body, and poor fusion and bonding between two glass bodies are not allowed. Visually, there should be no ripples, bubbles, or layered stripes caused by heterogeneity in the glass body of the brick. The concave surface of the large surface of the glass brick should be less than 1 millimeter, and the convex surface should be less than 2 millimeters. The weight should meet the quality standards, and there should be no quality defects such as surface warping, notches, and burrs. The angle should be square.

2. Listening to sound
The sound heard when hitting a craft glass wine bottle with your hand is different. In the wine bottle factory, the crystal material has a higher tone and a lingering feeling, while the tone of glass products is lower and has no echo.

3. Of course, if we want to accurately prove whether the glass bottle is qualified, we still need to conduct some testing and testing. However, we cannot do it on a daily basis. Judging the quality based on appearance can basically determine the quality.
