the two halves of the block during manufacture. Some manufacturers of glass blocks have developed a method of bonding two glass blocks together with adhesive, producing blocks of up to 160 mm (6½") thick with enhanced fire resistance. It is important that the block manufacturer's recommendations are followed with regards to the installation of fire resisting glass block walls, as without special construction techniques, the wall will not achieve the desired fire resistance.

Modern glass bricks were preceded by
Falconnier Hollow Glass Bricks in the late nineteenth century. Falconnier Bricks were blown glass bricks available in multiple colors and were formed in molds while the glass was molten. They could be used for walls or roofs and were joined with wire and cement.

Standards allow for variation in sizes and production irregularity. Blocks fall within three classifications; Class 1, Class 2 and Class 3 with Class 1 being the highest and best rating with a maximum permissible deviation from designed size and rectangularity of 1 mm.

Glass blocks can provide light and serve as a decorative addition to an architectural structure, but hollow glass blocks are non load-bearing unless stated otherwise. Hollow glass wall blocks are manufactured as two separate halves and, while the glass is still molten, the two pieces are pressed

Some hollow glass wall blocks are available in colored variants. These colored variants fall into two categories. The first type is manufactured with UV stable colored glass and can be used in the same locations as standard clear glass blocks. The second type utilizes a colored material (dye or

227:. Glass block walls are constrained based on the framing in which they are set. If a masonry or steel frame exists, the maximum area of the wall can be 144 square feet (13.4 m), whereas the maximum area without a frame is 100 square feet (9.3 m).
