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
there are lots of types of glasses which can be used for everyday object but some different types of glass include: annealed glass which is the first product of glass making and will then be turned into tougher glass, toughened glass which is less likely to break or crack and mirrored glass which will have a layer of silver or aluminium on one side this glass often makes mirrors.
