  2. Borosilicate glass - Wikipedia

    en.wikipedia.org/wiki/Borosilicate_glass

    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.

  3. Pipe smoking - Wikipedia

    en.wikipedia.org/wiki/Pipe_smoking

    Spoon pipes (glass pipes or glass bowl pipes) have become increasingly common with the rise of cannabis or other narcotics smoking. Spoon pipes are normally made of borosilicate glass to withstand repeated exposure to high temperatures. They consist of a bowl for packing material into, stem for inhaling, and a carburettor (carb) for controlling ...

  4. Cannabis smoking - Wikipedia

    en.wikipedia.org/wiki/Cannabis_smoking

    Pipes made for smoking cannabis, sometimes called pieces or bowls, are made of a variety of materials, including metal fittings, ceramic, borosilicate glass, stone, wood, bamboo among other materials. Subtypes include one-hitters, bubblers, chillums, glass blunts, corn cob pipes, and standard hand pipes. Pipes vary greatly in shape and ...

    An Italian-made chillum Traditional earthen chillum displayed for sale at Chawk Bazaar Jorhat, Assam. A chillum, or chilam, is a straight conical smoking pipe traditionally made of either clay or a soft stone (such as steatite or catlinite). It was used popularly in India in the eighteenth century and still often used to smoke marijuana.

  6. Glass-to-metal seal - Wikipedia

    en.wikipedia.org/wiki/Glass-to-metal_seal

    The borosilicate glass of usual laboratory glassware has a lower coefficient of thermal expansion than tungsten, thus it is necessary to use an intermediate sealing glass to get a stress-free seal. There are combinations of glass and iron-nickel-cobalt alloys where even the non-linearity of the thermal expansion is matched. These alloys can be ...

    250ml DURAN® laboratory bottle. DURAN is a brand name for the internationally defined borosilicate glass 3.3 (DIN ISO 3585) produced by the German company DURAN Group GmbH since 2005 under license from the Schott AG, which was the first to develop it, and which sold it from 1893 until the equity carve-out of the DURAN Group in 2005.

  8. Vycor - Wikipedia

    en.wikipedia.org/wiki/Vycor

    Vycor is the brand name of Corning's high-silica, high-temperature glass.It provides very high thermal shock resistance. Vycor is approximately 96% silica and 4% boron trioxide, but unlike pure fused silica, it can be readily manufactured in a variety of shapes.

  9. Transparent ceramics - Wikipedia

    en.wikipedia.org/wiki/Transparent_ceramics

    Several glasses are used in transparent armor, such as normal plate glass (soda-lime-silica), borosilicate glass, and fused silica. Plate glass has been the most common glass used due to its low cost. But greater requirements for the optical properties and ballistic performance have necessitated the development of new materials.
