Glass is a bit of a riddle. It's hard enough to protect us, but it shatters with incredible ease. It's made from opaque sand, yet it's completely transparent. And, perhaps most surprisingly of all, it behaves like a solid material... but it's also a sort of weird liquid in disguise!
Discover facts about glass and detailed glass information, including its natural materials, endless recyclability, and surprising advantages for packaging.
Glass is an amorphous (non-crystalline) solid. Because it is often transparent and chemically inert, glass has found widespread practical, technological, and decorative use in window panes, tableware, and optics.
Glass is an inorganic solid material that is usually transparent or translucent as well as hard, brittle, and impervious to the natural elements. What is glass made out of? Commercial glass is usually made of sand, limestone, and sodium carbonate that is raised in temperature until it is molten.

At its most basic level, glass is a solid material that is typically transparent or translucent and has a smooth, glossy surface. It is made by heating a mixture of silica (or silicon dioxide), soda ash, and lime to a high temperature until it melts and then allowing it to cool and solidify.
Glass has become so commonplace today that it’s easy to see right through it without a second thought. It’s in our windows, on our screens, in our cabinets, and in many of the devices we interact with every day. Even though glass can be found everywhere, you may live your whole life not knowing much about how it’s made or what it’s composed of.
