Division 8 – Doors & Windows

Door and Window Openings

Glass is made primarily of liquid sand; yes the sand you find on a beach. Made mostly of silicon dioxide, the sand is heated up until it turns into a liquid. Once cooled, it doesn’t turn back into sand, but rather the glass you see around you! Don’t worry about your favorite beach though, sand melts around 2930 °F (1610 °C).

When scientists were testing the first nuclear bomb, in New Mexico, the heat of the explosion turned the sand into glass! Called Trinitite, this glass is left behind on the desert floor of the Trinity testing site!
