Glass blocks - sward
Note the textured nature of the original glass surface (near edge) and the smoothly worn areas where people walked for 110 years. The large panel is an example of size A (~36 x 34.5").  The 2nd panel (size B) looks shinier because it is upside down; its textured and worn surface is facing down.
