Observe the lines on the bottle
●Feature description: High borosilicate glass bottles adopt a controlled production process, and there are no bottle lines on both sides of the bottle. In contrast, soda-lime glass bottles will have two bottle lines during the molding production process.
●Identification method: Directly observe whether there are obvious bottle lines on the bottle. If there are no bottle lines, it may be a high borosilicate glass bottle; if there are two bottle lines, it may be a soda-lime glass bottle.
Check the transparency and font changes
●Feature description: High borosilicate glass bottles have the characteristics of high transparency, bright and clear appearance, and no phantoms. At the same time, the fonts or patterns on them remain intact without deformation. Soda-lime glass bottles may have a phantom effect, causing the font or pattern to deform.
●Identification method: Place the glass bottle in a well-lit environment and observe whether its transparency and font are clear and not deformed. If the transparency is high and the font is intact, it may be a high borosilicate glass bottle; if there is a phantom effect or font deformation, it may be a soda-lime glass bottle.
Observe the surface quality of the bottle
●Feature description: The surface of the high borosilicate glass bottle is delicate and smooth, without defects such as bubbles and cracks. In contrast, the surface of the soda-lime glass bottle may be rough and have defects such as bubbles.
●Identification method: Carefully check whether the surface of the bottle is smooth and flawless. If the surface is delicate and smooth without obvious defects, it may be a high borosilicate glass bottle; if the surface is rough or has defects such as bubbles, it may be a soda-lime glass bottle.
IV. Consider other appearance characteristics
●Color uniformity: The color of high borosilicate glass bottles is usually more uniform, without obvious color difference or spots.
●Gloss: The glossiness of high borosilicate glass bottles is high, showing a crystal clear texture.
In summary, by observing the lines of the bottle, checking the transparency and font changes, observing the surface quality of the bottle, and considering other appearance characteristics, we can more accurately identify high borosilicate glass bottles. It should be noted that the above method is for reference only. If more accurate identification results are required, it is recommended to combine other professional testing methods for verification.
