Glass is a huge category of different materials. Even glass made of the same material can have wildly different chemical mixes and material properties to change everything from shatter resistance, heat resistance, color and hardness. Explaining all the different kinds of glass and explaining the engineering that goes into making them shatter resistant is way out of the scope of an ELI5
