1. Appearance:
(1). Check for bubbles: Good glass bottles have a smooth surface without bubbles or flaws.
(2). Check for uniformity: Good glass bottles have a flat bottom and consistent top diameter, with no debris, edges, or burrs at the rim.
2. Material:
(1). The material of the glass bottle must be borosilicate glass, which has excellent heat resistance and stability. Ordinary glass is prone to cracking.
(2). Check the light transmittance: Good glass bottles have high light transmittance, a bright surface, and no chromatic aberration when light passes through.
3. Weight:
Good glass bottles should be heavy because thicker glass bottles have higher compressive strength. At the same size, quality good glass bottles will have a weight that is relatively close.
4. Sound:
(1). Clear sound: Good glass bottles should produce a clear and loud sound when tapped, without any noise.
(2). Test different positions: Tap the glass bottle at different positions with your fingers and listen to the sound. Good glass bottles should produce the same sound at different positions. If there is a difference, it indicates that the glass bottle is damaged or has air holes.
These are some methods to identify the quality of glass bottles. I hope they can be helpful to everyone. When purchasing glass bottles, be sure to carefully inspect and choose quality glass bottles to ensure safety.
