Glass is manufactured in numerous variations tailored to structural and functional needs. Four fundamental types include Soda-Lime Glass (the most common commercial glass used for bottles and windows), Borosilicate Glass (thermal-resistant glass used in cookware and chemistry labs), Laminated Safety Glass (multi-layered glass bonded with an interlayer to prevent shattering upon impact), and Tempered Glass (thermally treated safety glass designed to crumble into small, blunt granular pieces rather than sharp shards when broken).
