    Did break i’ th’ rinsing. William Shakespeare, Henry VIII.

    Prompts to pursue the sparkling glass, besure
    ’Tis time to shun it. Phillips.

  1. Glass

    Glass is a non-crystalline, often transparent amorphous solid, that has widespread practical, technological, and decorative use in, for example, window panes, tableware, and optics. Glass is most often formed by rapid cooling (quenching) of the molten form; some glasses such as volcanic glass are naturally occurring. The most familiar, and historically the oldest, types of manufactured glass are "silicate glasses" based on the chemical compound silica (silicon dioxide, or quartz), the primary constituent of sand. Soda-lime glass, containing around 70% silica, account for around 90% of manufactured glass. The term glass, in popular usage, is often used to refer only to this type of material, although silica-free glasses often have desirable properties for applications in modern communications technology. Some objects, such as drinking glasses and eyeglasses, are so commonly made of silicate-based glass that they are simply called by the name of the material. Although brittle, silicate glass is extremely durable, and many examples of glass fragments exist from early glass-making cultures. Archaeological evidence suggests glass-making dates back to at least 3,600 BCE in Mesopotamia, Egypt, or Syria. The earliest known glass objects were beads, perhaps created accidentally during metal-working or the production of faience. Due to its ease of formability into any shape, glass has been traditionally used for vessels: bowls, vases, bottles, jars and drinking glasses. In its most solid forms, it has also been used for paperweights and marbles. Glass can be coloured by adding metal salts or painted and printed with vitreous enamels, leading to its use in stained glass windows and other glass art objects. The refractive, reflective and transmission properties of glass make glass suitable for manufacturing optical lenses, prisms, and optoelectronics materials. Extruded glass fibres have application as optical fibres in communications networks, thermal insulating material when matted as glass wool so as to trap air, or in glass-fibre reinforced plastic (fibreglass).


  1. glass

    Glass is a hard, brittle, transparent or translucent substance that is typically produced by supercooling a melted mixture, primarily consisting of silica, soda, and lime, and then solidifying it without crystallization. It is often used in applications like window panes, drinking containers, and eyewear due to its unique properties like the ability to refract, transmit and reflect light without scattering it. It can also undergo coloration, reinforcement or be tempered for additional properties.

Webster Dictionary

  13. Etymology: [OE. glas, gles, AS. gls; akin to D., G., Dan., & Sw. glas, Icel. glas, gler, Dan. glar; cf. AS. glr amber, L. glaesum. Cf. Glare, n., Glaze, v. t.]


  1. Glass

    Glass is an amorphous solid material that exhibits a glass transition, which is the reversible transition in amorphous materials from a hard and relatively brittle state into a molten or rubber-like state. Glasses are typically brittle and can be optically transparent. The most familiar type of glass, used for centuries in windows and drinking vessels, is soda-lime glass, composed of about 75% silica plus sodium oxide from soda ash, lime, and several minor additives. Often, the term glass is used in a restricted sense to refer to this specific use. From the 19th century, various types of fancy glass started to become significant branches of the decorative arts. Objects made out of glass include not only traditional objects such as vessels, paperweights, marbles, beads, but an endless range of sculpture and installation art as well. Colored glass is often used, though sometimes the glass is painted, innumerable examples exist of the use of stained glass. In science, however, the term glass is usually defined in a much wider sense, including every solid that possesses a non-crystalline structure and that exhibits a glass transition when heated towards the liquid state. In this wider sense, glasses can be made of quite different classes of materials: metallic alloys, ionic melts, aqueous solutions, molecular liquids, and polymers. For many applications polymer glasses are a lighter alternative to traditional silica glasses.

The Standard Electrical Dictionary

  1. Glass

    A fused mixture of silicates of various oxides. It is of extremely varied composition and its electric constants vary greatly. Many determinations of its specific resistance have been made. For flint glass at 100° C. (212° F.) about (2.06E14) ohms --at 60° C (140° F.) (1.020E15) (Thomas Gray) is given, while another observer (Beetz) gives for glass at ordinary temperatures an immeasurably high resistance. It is therefore a non-conductor of very high order if dry. As a dielectric the specific inductive capacity of different samples of flint glass is given as 6.57--6.85--7.4--10.1 (Hopkinson), thus exceeding all other ordinary dielectrics. The densest glass, other things being equal, has the highest specific inductive capacity.
