  2. Glass in green buildings - Wikipedia

    en.wikipedia.org/wiki/Glass_in_green_buildings

    Glass is a wholly recyclable material. [2] Glass is beloved by architects as well as designers. Glass can play a role in accomplishing greater indoor environmental quality and when used carefully can improve energy efficiency, however a measured approach needs to be taken to ensure the building loads are not excessively increased due to solar gain.

  3. Transparent ceramics - Wikipedia

    en.wikipedia.org/wiki/Transparent_ceramics

    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 generated the need for new materials. Chemical or thermal treatments can increase the strength of glasses, and the controlled crystallization of certain glass systems can produce transparent ...

  4. Bioactive glass - Wikipedia

    en.wikipedia.org/wiki/Bioactive_glass

    Bioactive metallic glass is a subset of bioactive glass, wherein the bulk material is composed of a metal-glass substrate and is coated with bioactive glass in order to make the material bioactive. The reasoning behind the introduction of the metallic base is to create a less brittle, stronger material that will be permanently implanted within ...

  5. Libyan desert glass - Wikipedia

    en.wikipedia.org/wiki/Libyan_desert_glass

    Libyan desert glass or Great Sand Sea glass is an impactite, made mostly of lechatelierite, [1] found in areas in the eastern Sahara, in the deserts of eastern Libya and western Egypt. Fragments of desert glass can be found over areas of tens of square kilometers. Like obsidian, it was knapped and used to make tools during the Pleistocene. [2]

  6. Ultra low expansion glass - Wikipedia

    en.wikipedia.org/wiki/Ultra_low_expansion_glass

    Diagram of process of making ULE glass. The way that ULE is made is very different from the standard way that glass is made. Instead of mixing powdered materials together into a batch, melting that batch and pouring out sheets of glass, ULE, being such a high temperature glass, has to be made in a flame hydrolysis process.

  7. Glass - Wikipedia

    en.wikipedia.org/wiki/Glass

    The refractive, reflective and transmission properties of glass make glass suitable for manufacturing optical lenses, prisms, and optoelectronics materials. Extruded glass fibres have applications as optical fibres in communications networks, thermal insulating material when matted as glass wool to trap air, or in glass-fibre reinforced plastic .

  8. Reflective surfaces (climate engineering) - Wikipedia

    en.wikipedia.org/wiki/Reflective_surfaces...

    The albedo of several types of roofs (lower values means higher temperatures). Reflective surfaces, or ground-based albedo modification (GBAM), is a solar radiation management method of enhancing Earth's albedo (the ability to reflect the visible, infrared, and ultraviolet wavelengths of the Sun, reducing heat transfer to the surface).

  9. List of physical properties of glass - Wikipedia

    en.wikipedia.org/wiki/List_of_physical...

    Unless stated otherwise, the properties of fused silica (quartz glass) and germania glass are derived from the SciGlass glass database by forming the arithmetic mean of all the experimental values from different authors (in general more than 10 independent sources for quartz glass and T g of germanium oxide glass). The list is not exhaustive.
