The quality of glass bottles can be based on national standards. A large proportion of glass bottles are used for foods and beverages. The requirements for such glass bottles are not only general indicators such as appearance quality, but also the thermal stability and chemical stability of the products. Because the glass bottles are to be autoclaved before filling, it is emphasized that these products have high thermal stability. For the preservation of pickles, fermented milk and other products, in order to ensure the quality, the glass bottles are required to have reliable chemical stability.
