Abstract: As an article of manufacture, a glass block panel comprising a plurality of glass blocks having a circumferential rib around the edges thereof. The glass blocks are uniformly spaced apart edge to edge in a width and breadth direction by longitudinal spacer members. The spacer members are provided with grooves for receiving therein the circumferential rib of the glass blocks. The spacer members are laterally slotted to the center from one side thereof and are interconnected to form a reticular framework between the glass blocks. The reticular framework provides a mortar space between the glass blocks at the faces thereof in which are fitted spacer bars longitudinally abutting against the edges of the spacer members. Further provided in the spaces between the glass blocks is caulking material to form the mortar like joints between the glass blocks of the panel. Banding means are tightened circumferentially around the edges of the glass blocks to secure the panel as an article of manufacture.
