Several applications of silicate glasses derive from their optical transparency, supplying rise to their Main use as window panes. Glass will transmit, replicate and refract light-weight; these qualities can be enhanced by slicing and sprucing for making optical lenses, prisms, high-quality glassware, and optical fibers for top speed knowledge transmission by mild. Glass is often coloured by adding metallic salts, and can even be painted and printed with vitreous enamels. These attributes have led on the intensive usage of glass inside the manufacture of artwork objects and particularly, stained glass windows. Though brittle, silicate glass is extremely resilient, and a lot of samples of glass fragments exist from early glass-earning cultures.

Amorphous metallic wires have been produced by sputtering molten steel on to a spinning metallic disk. Far more a short while ago a number of alloys are manufactured in levels with thickness exceeding 1 millimeter. These are typically often known as bulk metallic glasses (BMG). Liquidmetal Technologies market numerous zirconium-based BMGs. Batches of amorphous steel have also been produced streaming glass that display mechanical Houses much exceeding All those located in regular metal alloys.[133][134][one hundred thirty five]
