All-silica fiber

All-silica fiber, or silica-silica fiber, is an optical fiber whose core and cladding are made of silica glass. The refractive index of the core glass is higher than that of the cladding. These fibers are typically step-index fibers. The cladding of an all-silica fiber should not be confused with the polymer overcoat of the fiber.


Annealing (glass)

Annealing of glass is a process of slowly cooling hot glass objects after they have been formed, to relieve residual internal stresses introduced during manufacture. Especially for smaller, simpler objects, annealing may be incidental to the process of manufacture, but in larger or more complex products it commonly demands a special process of annealing in a temperature-controlled kiln known as a lehr. Annealing of glass is critical to its durability. Glass that has not been properly annealed retains thermal stresses caused by quenching, which indefinitely decrease the strength and reliabi ...


Bologna bottle

A Bologna bottle, also known as a Bologna phial or philosophical vial, is a glass bottle which has great external strength, often used in physics demonstrations and magic tricks. The exterior is generally strong enough that one could pound a nail into a block of wood using the bottle as a hammer; however, even a small scratch on the interior would cause it to crumble. It is created by heating a glass bottle and then rapidly cooling the outside whilst slowly cooling the inside. This causes external compression and internal tension such that even a scratch on the inside is sufficient to shat ...


Central Glass and Ceramic Research Institute

Central Glass and Ceramic Research Institute is a Kolkata based National research institute under Council of Scientific and Industrial Research, India. Established in 1950 it focuses on the area of glass, ceramics, mica, refractories etc.



ClearCurve is Cornings brand name for a new optical fiber that can be bent around short-radius curves without losing its signal. It is constructed with a conventional fiber on the inside, surrounded by a cladding containing a new nanostructured reflector. ClearCurve is hundreds of times more flexible than conventional optical cable, transmitting high-quality signals even when wrapped around small objects like a pen, where a conventional cable would lose the signal completely. Although originally introduced to serve the needs of pulling fiber in apartment buildings and other high-density un ...



Dragontrail, manufactured by Asahi Glass Co., is an alkali-aluminosilicate sheet glass engineered for a combination of thinness, lightness and damage-resistance, similar to Cornings proprietary Gorilla Glass. The materials primary properties are its strength, allowing thin glass without fragility; its high scratch resistance; and its hardness – with a Vickers hardness test rating of 595 to 673.
