Soda–lime glass (for containers) [2] Borosilicate (low expansion, similar to Pyrex, Duran) Glass wool (for thermal insulation) Special optical glass (similar to Lead crystal) Fused silica Germania glass Germanium selenide glass Chemical composition, wt% 74 SiO 2, 13 Na 2 O, 10.5 CaO, 1.3 Al 2 O 3, 0.3 K 2 O, 0.2 SO 3, 0.2 MgO, 0.01 TiO 2, 0. ...
In general opaque glass can devit easily as crystals are present in the glass to give its opaque appearance and thus the higher the chance it might devit. Techniques for avoiding devitrification include cleaning the glass surfaces of dust or unwanted residue, and allowing rapid cooling once the piece reaches the desired temperature, until the ...
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 ...
Sidewalk skylight (also named 'pavement light') made of load-bearing glass bricks in Burlington House, London. Glass brick, also known as glass block, is an architectural element made from glass. The appearance of glass blocks can vary in color, size, texture and form. Glass bricks provide visual obscuration while admitting light.
A newer, alkali-free (<2%) type, E-glass, is an alumino-borosilicate glass. [10] C-glass was developed to resist attack from chemicals, mostly acids that destroy E-glass. [10] T-glass is a North American variant of C-glass. AR-glass is alkali-resistant glass. Most glass fibers have limited solubility in water but are very dependent on pH.
Rippled glass refers to textured glass with marked surface waves. [1] Louis Comfort Tiffany made use of such textured glass to represent, for example, water or leaf veins. The texture is created during the glass sheet-forming process. A sheet is formed from molten glass with a roller that spins on itself, while travelling forward.
Smart glass has been used in some small-production cars including the Ferrari 575 M Superamerica. [20] ICE 3 high speed trains use electrochromic glass panels between the passenger compartment and the driver's cabin. The elevators in the Washington Monument use smart glass in order for passengers to view the commemorative stones inside the ...
A pendant made from modern dichroic glass. Dichroic glass is glass which can display multiple different colors depending on lighting conditions.. One dichroic material is a modern composite non-translucent glass that is produced by stacking layers of metal oxides which give the glass shifting colors depending on the angle of view, causing an array of colors to be displayed as an example of ...
