Prism Glass
Prism glass is architectural glass used around the turn of the century to provide lighting to underground spaces and areas that would otherwise be too difficult to light. Prism glass uses a unique convex lens design to help illuminate more than ordinary glass. Prism glass can sometimes be found on sidewalks and in this form is known as vault lighting. It is similar to deck prisms that were used to light spaces below deck on sailing ships.
