Its disadvantages are large mass (mass to capacity ratio), brittleness and fragility. However, with the new technology of thin-wall and light weight and physical and chemical tempering, these shortcomings have been significantly improved, so the production of glass bottles can increase year by year under the fierce competition with plastics, tins and cans.
