Glass block wall in Chicago. 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 together and annealed.
Glass block, also known as glass brick, is an architectural element made from glass used in areas where privacy or visual obscuration is desired while admitting light, such as underground parking garages, washrooms, and municipal swimming baths. Glass block was originally developed in the early 1900s to provide natural light in industrial ...
While typical clear float glass blocks approximately 45% of UV radiation, the addition of CeOx to glass [16] has been shown to further reduce UV transmission as well as widespread use of organic UV blocking dyes in the production of acrylic substrates. [17] Most soda-lime glass completely absorbs short wavelength UV-B radiation below 300 nm.
In the 1950s, Pilkington Bros., England, developed the float glass process, producing high-quality distortion-free flat sheets of glass by floating on molten tin. [21] Modern multi-story buildings are frequently constructed with curtain walls made almost entirely of glass. [47] Laminated glass has been widely applied to vehicles for windscreens ...
Borosilicate glass is a type of glass with silica and boron trioxide as the main glass-forming constituents. Borosilicate glasses are known for having very low coefficients of thermal expansion (≈3 × 10 −6 K −1 at 20 °C), making them more resistant to thermal shock than any other common glass.

This glass pattern was used for stemware and tableware, and continued to be produced until 1988. [64] Described as "block geometric", its appearance was very different from other patterns when it was introduced. Most glass made with the American pattern was produced using Fostoria's high-quality crystal formula. [65]
