the highest quality of glass will contain the chemical formula of SiO2 and the equations of glass production include

physical properties of annealed glass are low toughness, breaks from sudden change to high or low temperature and when it breaks it form sharp fragments
the main chemical properties of annealed glass are sand and alkali
