  2. Glass coloring and color marking - Wikipedia

    en.wikipedia.org/wiki/Glass_coloring_and_color...

    The color is caused by the size and dispersion of gold particles. Ruby gold glass is usually made of lead glass with added tin. Silver compounds such as silver nitrate and silver halides can produce a range of colors from orange-red to yellow. The way the glass is heated and cooled can significantly affect the colors produced by these compounds.

  3. 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 ...

  4. Glass-ceramic - Wikipedia

    en.wikipedia.org/wiki/Glass-ceramic

    In the visible range glass-ceramics can be transparent, translucent or opaque and even colored by coloring agents. However, glass-ceramic is not totally unbreakable. Because it is still a brittle material as glass and ceramics are, it can be broken – in particular it is less robust than traditional cooktops made of steel or cast iron.

  5. Uranium glass - Wikipedia

    en.wikipedia.org/wiki/Uranium_glass

    Uranium glass was made into tableware and household items, but fell out of widespread use when the availability of uranium to most industries was sharply curtailed during the Cold War in the 1940s to 1990s, with the vast majority of the world's uranium supply being utilised as a strategic material for use in nuclear weapons or nuclear power.

  6. Glass - Wikipedia

    en.wikipedia.org/wiki/Glass

    Fibreglass (also called glass fibre reinforced plastic, GRP) is a composite material made by reinforcing a plastic resin with glass fibres. It is made by melting glass and stretching the glass into fibres. These fibres are woven together into a cloth and left to set in a plastic resin.

  7. Trinitite - Wikipedia

    en.wikipedia.org/wiki/Trinitite

    The color of the glass is a pale bottle green, and the material is extremely vesicular with the size of the bubbles ranging to nearly the full thickness of the specimen." [ 3 ] The most common form of trinitite is green fragments of 1–3 cm thick, smooth on one side and rough on the other; this is the trinitite that cooled after landing still ...

  8. Optical glass - Wikipedia

    en.wikipedia.org/wiki/Optical_glass

    These materials give glass its characteristic non-crystalline structure. The addition of materials such as alkali metals, alkaline-earth metals or rare earths can change the physico-chemical properties of the whole to give the glass the qualities suited to its function. Some optical glasses use up to twenty different chemical components to ...

  9. Glass transition - Wikipedia

    en.wikipedia.org/wiki/Glass_transition

    Other materials, such as many polymers, lack a well defined crystalline state and easily form glasses, even upon very slow cooling or compression. The tendency for a material to form a glass while quenched is called glass forming ability. This ability depends on the composition of the material and can be predicted by the rigidity theory. [12]
