Nowadays, an increasing number of glass water bottles are made of High Borosilicate Glass, which is a special type of glass made from boron, silicon, oxygen, and other metal oxides. It has high heat resistance, resistance to thermal shock, corrosion resistance, and chemical stability. It has high melting and softening points, can withstand high pressure and rapid changes in temperature under high temperature, and has excellent physical properties and chemical stability, which is why more and more glass water bottles are made of High Borosilicate Glass.
When we purchase glass water bottles, we may notice an interesting phenomenon that the silicone ring on the lid is not assembled but is placed directly inside the bottle. Why is this? Let's take a closer look.
Both the silicone ring and High Borosilicate Glass contain silicon ions. If the silicone ring is assembled on the lid when it leaves the factory, chemical reactions may occur between the silicone ring and the mouth of the water bottle over time, and silicon ions will become free between the two. When the bottle is opened, the silicone ring will stick to the mouth of the bottle. In addition, there is a certain period of time required for sales, so the silicone ring is usually placed inside the bottle instead of being assembled on the lid.
When we purchase a glass water bottle, the silicone ring will form a layer of oxide film when it encounters water, which prevents the reaction between the silicone ring and the bottle, so we will not encounter this problem during use.
