There are many types of glass, but the classification of glass bottles is divided into soda lime glass and borosilicate glass.
Do you want to know how to distinguish glass bottles of different materials? If you want to know, please read below.
1.【Difference of ingredients】
Ordinary soda lime glass is mainly composed of silicon, sodium and calcium. The composition of borosilicate glass is mainly silicon and boron, so we can see their material composition from their two names.
2. [The difference in performance]
Generally speaking, the performance of soda lime glass is not as good as that of high borosilicate glass. This not only refers to the heat resistance, but also the difference in viewing. The high borosilicate glass frit is made of glass tubes cut into glass bottles, so there will be no sutures and marks such as scissors. And soda-lime glass is cut short by melted glass frit and then machine-formed, so there will be stripes, material marks and scissors marks.
3.【Difference in appearance】
High borosilicate glass and sodium calcium glass, if they are formed by feeding and pressing, will not have a circle of cold lines. If they are formed in other ways, there will be cold lines. For example, high borosilicate glass is usually Mainly by hand blowing, there will be no cold streaks. Moreover, borosilicate glass is usually lighter in weight, the bottle wall and bottom are uniform in thickness, and the light refraction is uniform; on the contrary, soda lime glass can clearly see that the bottom of the bottle is thicker, and the light refraction is uneven.
4.【Difference in density】
Generally, the density of borosilicate glass is lower than that of soda lime glass, which can be compared by buoyancy measurement.
5.【The difference in heat resistance】
High borosilicate glass has strong heat resistance, while the heat resistance of soda lime glass is relatively poor. The thermal shock of high borosilicate glass is generally 100 to 200 degrees, and the soda lime glass is generally only 80 degrees.
