New study uncovers 'magnetic' memory of European glass eels

A new study led by researchers at the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science and at the Institute of Marine Research in Norway found that European glass eels use their magnetic sense ...

Process for making ductile glass discovered

If you've ever dropped your smartphone on a concrete floor, you know that dreaded feeling as you turn it over to see how badly the screen has cracked—but that stress may soon be a thing of the past. Researchers at Rensselaer ...

What does the future of plastic look like?

Plastic waste is a growing problem around the world, despite efforts to recycle or reduce plastic use. In order to really transform the recycling process, more attention needs to be paid to the composition of plastic, according ...

New method for the measurement of nano-structured light fields

Structured laser light has already opened up various different applications: it allows for precise material machining, trapping, manipulating or defined movement of small particles or cell compartments, as well as increasing ...

How to bend flat glass perfectly around corners

Researchers from the Fraunhofer Institute for Mechanics of Materials IWM have developed a new process that can bend sheets of glass to produce angular corners. Unlike conventional processes, this does not impair the optical ...

Glass

Glass generally refers to hard, brittle, transparent material, such as those used for windows, many bottles, or eyewear. Examples of such solid materials include, but are not limited to, soda-lime glass, borosilicate glass, acrylic glass, sugar glass, isinglass (Muscovy-glass), or aluminium oxynitride. In the technical sense, glass is an inorganic product of fusion which has been cooled through the glass transition to a rigid condition without crystallizing. Many glasses contain silica as their main component and glass former.

In the scientific sense the term glass is often extended to all amorphous solids (and melts that easily form amorphous solids), including plastics, resins, or other silica-free amorphous solids. In addition, besides traditional melting techniques, any other means of preparation are considered, such as ion implantation, and the sol-gel method. However, glass science and physics commonly includes only inorganic amorphous solids, while plastics and similar organics are covered by polymer science, biology and further scientific disciplines.

Glass plays an essential role in science and industry. The optical and physical properties of glass make it suitable for applications such as flat glass, container glass, optics and optoelectronics material, laboratory equipment, thermal insulator (glass wool), reinforcement fiber (glass-reinforced plastic, glass fiber reinforced concrete), and art.

The term glass developed in the late Roman Empire. It was in the Roman glassmaking center at Trier, Germany, that the late-Latin term glesum originated, probably from a Germanic word for a transparent, lustrous substance.
