  2. Vitrification - Wikipedia

    en.wikipedia.org/wiki/Vitrification

    The most common applications are in the making of pottery, glass, and some types of food, but there are many others, such as the vitrification of an antifreeze-like liquid in cryopreservation. In a different sense of the word, the embedding of material inside a glassy matrix is also called vitrification. An important application is the ...

  3. Hexactinellid - Wikipedia

    en.wikipedia.org/wiki/Hexactinellid

    They are more-or-less cup-shaped animals, ranging from 10 to 30 centimetres (3.9 to 11.8 in) in height, with sturdy skeletons made of glass-like silica spicules, fused to form a lattice. [ 4 ] [ 5 ] In some glass sponges such as members of the genus Euplectela , these structures are aided by a protein called glassin.

  4. 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 .

  5. Amorphous solid - Wikipedia

    en.wikipedia.org/wiki/Amorphous_solid

    The terms "glass" and "glassy solid" are sometimes used synonymously with amorphous solid; however, these terms refer specifically to amorphous materials that undergo a glass transition. [1] Examples of amorphous solids include glasses, metallic glasses, and certain types of plastics and polymers. [2] [3]

  6. Transparency and translucency - Wikipedia

    en.wikipedia.org/wiki/Transparency_and_translucency

    Materials that allow the transmission of light waves through them are called optically transparent. Chemically pure (undoped) window glass and clean river or spring water are prime examples of this. Materials that do not allow the transmission of any light wave frequencies are called opaque. Such substances may have a chemical composition which ...

  7. 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.

  9. Rotating locomotion in living systems - Wikipedia

    en.wikipedia.org/wiki/Rotating_locomotion_in...

    Among animals, there exists a single known example of an apparently freely rotating structure, though it is used for digestion rather than propulsion: the crystalline style of certain bivalves and gastropods. [19]: 89 The style consists of a transparent glycoprotein rod which is continuously formed in a cilia-lined sac and extends into the stomach.
