Safety glass

Glass with features that make it less likely to cause injury

Safety glass is glass with additional safety features that make it less likely to break, or less likely to become a hazard when broken. Common designs include toughened glass (also known as tempered glass), laminated glass, and wire mesh glass (also known as wired glass). Toughened glass was invented in 1874 by Francois Barthelemy Alfred Royer de la Bastie.
