Due to the brittleness of <a href=\"https:\/\/info.glass.com\/glass-dictionary\/glass\/\" target=\"_blank\" rel=\"noopener\">glass<\/a>, bending must happen while the glass is still warm enough to be manipulated but not so hot that it is molten. To bend glass, manufacturers place a piece of glass over a piece of metal made to simulate the curve needed for the glass. Both the metal and glass are placed into an oven and heated until the glass begins to soften, at which point both the glass and the metal form are removed from the heat. If left alone, gravity will pull the softened glass down and onto the shape of the intended curve, or an outside force can apply pressure to hasten the bending process.<\/p>\n<p>&nbsp;<\/p>\n\t\t\t\t\t\t<\/div>\r\n\t\t\t\t\t<\/div>\r\n\t\t\t\t\t\r\n\t\t\t\t\t<a class=\"dictionary-to-top\" href=\"#dictionary-top\">Back to top<\/a>\r\n\t\t\t\t<\/article>\r\n\r\n\t\t\t\t\t\t\t\t\r\n\t\t\t\t\t\t\t\t\r\n\t\t\t\t\r\n\t\t\t\t\r\n\t\t\t\t<article class=\"dictionary-entry clearfix\" id=\"beveled-glass\">\r\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<div class=\"dictionary-entry__img-container\">\r\n\t\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"150\" height=\"150\" src=\"https:\/\/www.glass.com\/info\/wp-content\/uploads\/2018\/05\/beveled-glass-150x150.jpeg\" class=\"dictionary-entry__img wp-post-image\" alt=\"beveled glass\" \/>\t\t\t\t\t\t<\/div>\r\n\t\t\t\t\t\t\t\t\t\t<div class=\"dictionary-entry__details-container\">\r\n\t\t\t\t\t\t<h2 class=\"dictionary-entry__headline\"><a href=\"https:\/\/www.glass.com\/info\/glass-dictionary\/beveled-glass\/\">Beveled Glass<\/a><\/h2>\r\n\t\t\t\t\t\t<div class=\"dictionary-entry__content\">\r\n\t\t\t\t\t\t\t<p>Thick pieces of glass with the edges cut on an angle is beveled glass.

The resulting matter is a non-crystalline structure. The most common kind of glass is silicate glass, which consists mainly of silica or silicon dioxide (SiO2). Silicon dioxide is the chemical makeup of sand, which is why many people say that glass is made from sand\u2014it is a primary component.<br \/>\nOther substances can be added to make different kinds of glass. Boron oxide added to the mixture will make a tougher glass that remains solid at high temperatures, such as the glass used in kitchens and laboratories. Iron alters optical properties of glass and can be found in <a href=\"https:\/\/info.glass.com\/glass-dictionary\/decorative-glass\/\" target=\"_blank\" rel=\"noopener\">decorative glass<\/a> applications. Glass can be colored by adding metallic salts, and can also be painted after manufacturing.<br \/>\nGlass both reflects and refracts light. Cutting and polishing glass in certain ways enhance these qualities and create optical lenses, prisms, fine glassware, and optical fibers for high speed data transmission by light.<\/p>\n\t\t\t\t\t\t<\/div>\r\n\t\t\t\t\t<\/div>\r\n\t\t\t\t\t\r\n\t\t\t\t\t<a class=\"dictionary-to-top\" href=\"#dictionary-top\">Back to top<\/a>\r\n\t\t\t\t<\/article>\r\n\r\n\t\t\t\t\t\t\t\t\r\n\t\t\t\t\t\t\t\t\r\n\t\t\t\t\r\n\t\t\t\t\r\n\t\t\t\t<article class=\"dictionary-entry clearfix\" id=\"glass-block\">\r\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<div class=\"dictionary-entry__img-container\">\r\n\t\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"150\" height=\"150\" src=\"https:\/\/www.glass.com\/info\/wp-content\/uploads\/2017\/09\/glass-brick-150x150.jpg\" class=\"dictionary-entry__img wp-post-image\" alt=\"Glass brick wall\" \/>\t\t\t\t\t\t<\/div>\r\n\t\t\t\t\t\t\t\t\t\t<div class=\"dictionary-entry__details-container\">\r\n\t\t\t\t\t\t<h2 class=\"dictionary-entry__headline\"><a href=\"https:\/\/www.glass.com\/info\/glass-dictionary\/glass-block\/\">Glass block<\/a><\/h2>\r\n\t\t\t\t\t\t<div class=\"dictionary-entry__content\">\r\n\t\t\t\t\t\t\t<p>Glass that is made generally smaller and significantly thicker than traditional windows and look like building blocks are called glass blocks.

Warm edge spacers create an additional layer to heat loss through the windows; some spacers may help absorb moisture.<\/p>\n\t\t\t\t\t\t<\/div>\r\n\t\t\t\t\t<\/div>\r\n\t\t\t\t\t\r\n\t\t\t\t\t<a class=\"dictionary-to-top\" href=\"#dictionary-top\">Back to top<\/a>\r\n\t\t\t\t<\/article>\r\n\r\n\t\t\t\t\t\t\t\t\r\n\t\t\t\t\t\t\t\t\r\n\t\t\t\t\r\n\t\t\t\t\r\n\t\t\t\t<article class=\"dictionary-entry clearfix\" id=\"glass-stove-top\">\r\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<div class=\"dictionary-entry__img-container\">\r\n\t\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"150\" height=\"150\" src=\"https:\/\/www.glass.com\/info\/wp-content\/uploads\/2018\/09\/glass_stovetop-150x150.jpg\" class=\"dictionary-entry__img wp-post-image\" alt=\"A sliver pan sits on a glass stove top filled with cut up yellow and red peppers.\" \/>\t\t\t\t\t\t<\/div>\r\n\t\t\t\t\t\t\t\t\t\t<div class=\"dictionary-entry__details-container\">\r\n\t\t\t\t\t\t<h2 class=\"dictionary-entry__headline\"><a href=\"https:\/\/www.glass.com\/info\/glass-dictionary\/glass-stove-top\/\">Glass Stove Top<\/a><\/h2>\r\n\t\t\t\t\t\t<div class=\"dictionary-entry__content\">\r\n\t\t\t\t\t\t\t<p>The glass stove top is made of a glass-ceramic blend that provides the stove top with the strength and heat-resistance needed to sit atop heating elements.

According to the Corning website, the science behind Gorilla Glass was created in the 1960s but the product created then is compositionally different from the various incarnations of Gorilla Glass available today (there are four kinds of Gorilla Glass on the market).

Unless the windows are made to prevent that heat transfer, a building would require more energy for heating and cooling the interior. One way to prevent heat transfer is with heat-absorbing tint or <a href=\"https:\/\/info.glass.com\/glass-dictionary\/window-film\/\" target=\"_blank\" rel=\"noopener\">window film<\/a>. Often an aftermarket application, window tint\u2014a type of window film made specifically to darken the glass or reflect light\u2014will reduce glare and absorb solar heat from the outside. Certain colors, particularly bronze, green, or gray tint will lower heat transfer (prevent heat from entering or leaving through a closed window) by up to 45 percent. Lowering the heat transfer reduces the energy costs for keeping the building interior stable. While heat-absorbing films are made to be practical, they also do offer a certain decorative element, though not on the scale that decorative window film provides. Decorative film does not generally provide heat-absorbing properties.<\/p>\n\t\t\t\t\t\t<\/div>\r\n\t\t\t\t\t<\/div>\r\n\t\t\t\t\t\r\n\t\t\t\t\t<a class=\"dictionary-to-top\" href=\"#dictionary-top\">Back to top<\/a>\r\n\t\t\t\t<\/article>\r\n\r\n\t\t\t\t\t\t\t\t\r\n\t\t\t\t\t\t\t\t\r\n\t\t\t\t\r\n\t\t\t\t\r\n\t\t\t\t<article class=\"dictionary-entry clearfix\" id=\"high-performance-glass\">\r\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<div class=\"dictionary-entry__img-container\">\r\n\t\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"150\" height=\"150\" src=\"https:\/\/www.glass.com\/info\/wp-content\/uploads\/2017\/09\/high-performance-glass-150x150.jpg\" class=\"dictionary-entry__img wp-post-image\" alt=\"Glass skyscraper.\" \/>\t\t\t\t\t\t<\/div>\r\n\t\t\t\t\t\t\t\t\t\t<div class=\"dictionary-entry__details-container\">\r\n\t\t\t\t\t\t<h2 class=\"dictionary-entry__headline\"><a href=\"https:\/\/www.glass.com\/info\/glass-dictionary\/high-performance-glass\/\">High performance glass<\/a><\/h2>\r\n\t\t\t\t\t\t<div class=\"dictionary-entry__content\">\r\n\t\t\t\t\t\t\t<p>The phrase high performance glass is a broad description that can encompass any added benefit the glass provides, other than a general, practical component.

The lamination prevents those tiny shards of glass from flying if, for example, the glass were to be hit by an object that, under normal circumstances, would propel them with some force.<\/p>\n\t\t\t\t\t\t<\/div>\r\n\t\t\t\t\t<\/div>\r\n\t\t\t\t\t\r\n\t\t\t\t\t<a class=\"dictionary-to-top\" href=\"#dictionary-top\">Back to top<\/a>\r\n\t\t\t\t<\/article>\r\n\r\n\t\t\t\t\t\t\t\t\r\n\t\t\t\t\t\t\t\t\r\n\t\t\t\t\r\n\t\t\t\t\r\n\t\t\t\t<article class=\"dictionary-entry clearfix\" id=\"lateral-wind-load\">\r\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<div class=\"dictionary-entry__img-container\">\r\n\t\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"150\" height=\"150\" src=\"https:\/\/www.glass.com\/info\/wp-content\/uploads\/2019\/10\/lateral-wind-load-150x150.png\" class=\"dictionary-entry__img wp-post-image\" alt=\"A cartoon blue house being blown off a gray slab.\" \/>\t\t\t\t\t\t<\/div>\r\n\t\t\t\t\t\t\t\t\t\t<div class=\"dictionary-entry__details-container\">\r\n\t\t\t\t\t\t<h2 class=\"dictionary-entry__headline\"><a href=\"https:\/\/www.glass.com\/info\/glass-dictionary\/lateral-wind-load\/\">Lateral Wind Load<\/a><\/h2>\r\n\t\t\t\t\t\t<div class=\"dictionary-entry__content\">\r\n\t\t\t\t\t\t\t<p>Lateral wind load is a type of <a href=\"https:\/\/info.glass.com\/glass-dictionary\/wind-load\/\" target=\"_blank\" rel=\"noopener\"><u>wind load<\/u><\/a> that describes the amount of horizontal force a structure can endure before being pushed off of its foundation.<\/p>\n\t\t\t\t\t\t<\/div>\r\n\t\t\t\t\t<\/div>\r\n\t\t\t\t\t\r\n\t\t\t\t\t<a class=\"dictionary-to-top\" href=\"#dictionary-top\">Back to top<\/a>\r\n\t\t\t\t<\/article>\r\n\r\n\t\t\t\t\t\t\t\t\r\n\t\t\t\t\t\t\t\t\r\n\t\t\t\t\r\n\t\t\t\t\r\n\t\t\t\t<article class=\"dictionary-entry clearfix\" id=\"layered-glass-multi-layered-glass\">\r\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<div class=\"dictionary-entry__img-container\">\r\n\t\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"150\" height=\"150\" src=\"https:\/\/www.glass.com\/info\/wp-content\/uploads\/2020\/03\/layered-glass-150x150.jpg\" class=\"dictionary-entry__img wp-post-image\" alt=\"layered-glass\" srcset=\"https:\/\/www.glass.com\/info\/wp-content\/uploads\/2020\/03\/layered-glass-150x150.jpg 150w, https:\/\/www.glass.com\/info\/wp-content\/uploads\/2020\/03\/layered-glass-300x300.jpg 300w, https:\/\/www.glass.com\/info\/wp-content\/uploads\/2020\/03\/layered-glass.jpg 500w\" sizes=\"(max-width: 150px) 100vw, 150px\" \/>\t\t\t\t\t\t<\/div>\r\n\t\t\t\t\t\t\t\t\t\t<div class=\"dictionary-entry__details-container\">\r\n\t\t\t\t\t\t<h2 class=\"dictionary-entry__headline\"><a href=\"https:\/\/www.glass.com\/info\/glass-dictionary\/layered-glass-multi-layered-glass\/\">Layered Glass \/ Multi-Layered Glass<\/a><\/h2>\r\n\t\t\t\t\t\t<div class=\"dictionary-entry__content\">\r\n\t\t\t\t\t\t\t<p>Layered or multi-layered glass gets its name from the process of layering glass, sometimes of different colors, together into one piece usually of substantial size.

One way of achieving a certain aesthetic is to paint the glass; however, painted wine glasses differ from painted architectural glass. While both may be hand painted by individual artists projecting a specific image, architectural glass frequently is painted on the back of the glass, so that the color (and\/or image) is viewed through the glass from a particular side. In general, those viewing the painted glass would not be able to access the paint itself. Painted architectural glass can range from a single, solid color to different colors and patterns or images, depending on application, and placement. If painted architectural glass includes a specific image, that image would be applied in layers opposite of traditional painting as each successive layer has to be seen through the glass and the last layer cannot be smaller than the first layer applied.<\/p>\n\t\t\t\t\t\t<\/div>\r\n\t\t\t\t\t<\/div>\r\n\t\t\t\t\t\r\n\t\t\t\t\t<a class=\"dictionary-to-top\" href=\"#dictionary-top\">Back to top<\/a>\r\n\t\t\t\t<\/article>\r\n\r\n\t\t\t\t\t\t\t\t\r\n\t\t\t\t\t\t\t\t\r\n\t\t\t\t\r\n\t\t\t\t\r\n\t\t\t\t<article class=\"dictionary-entry clearfix\" id=\"panoramic-sunroof\">\r\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<div class=\"dictionary-entry__img-container\">\r\n\t\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"150\" height=\"150\" src=\"https:\/\/www.glass.com\/info\/wp-content\/uploads\/2018\/05\/panoramic-sunroof-150x150.jpg\" class=\"dictionary-entry__img wp-post-image\" alt=\"sunroof, panoramic\" \/>\t\t\t\t\t\t<\/div>\r\n\t\t\t\t\t\t\t\t\t\t<div class=\"dictionary-entry__details-container\">\r\n\t\t\t\t\t\t<h2 class=\"dictionary-entry__headline\"><a href=\"https:\/\/www.glass.com\/info\/glass-dictionary\/panoramic-sunroof\/\">Panoramic Sunroof<\/a><\/h2>\r\n\t\t\t\t\t\t<div class=\"dictionary-entry__content\">\r\n\t\t\t\t\t\t\t<p>Glass in a vehicle roof that allows occupants to see the sky are referred to as sunroofs.

The film, generally referred to as window film, as it is most frequently applied to windows, can be either functional or decorative in nature.<\/p>\n<p>After-market window film can be used as part of safety or security glazing anchoring systems, providing an extra layer of protection to catch broken glass and slow the entrance of debris into a space that has been breached.<\/p>\n<p>Film also provides options for less expensive and less permanent decorative options for glass, ranging from different colors to a frosted or etched look, nearly all of which can be cut and layered to create images, patterns or depth. The most commonly known window film application, though, is for solar control, such as the tint on car windows. However, solar control window film is available in different degrees of tint, spanning from nearly transparent to the darkest tint, what most people know as \u201climo tint.\u201d<\/p>\n<p>After a rigorous cleaning of the glass, window film is applied with a solution of soapy water, which creates the surface tension needed to hold the film in place. Most window films have an adhesive that bonds with the glass once the water solution dries, though there are some that are adhesive free.<\/p>\n\t\t\t\t\t\t<\/div>\r\n\t\t\t\t\t<\/div>\r\n\t\t\t\t\t\r\n\t\t\t\t\t<a class=\"dictionary-to-top\" href=\"#dictionary-top\">Back to top<\/a>\r\n\t\t\t\t<\/article>\r\n\r\n\t\t\t\t\t\t\t\t\r\n\t\t\t\t\t\t\t\t\r\n\t\t\t\t\r\n\t\t\t\t\r\n\t\t\t\t<article class=\"dictionary-entry clearfix\" id=\"window-frames\">\r\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<div class=\"dictionary-entry__img-container\">\r\n\t\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"150\" height=\"150\" src=\"https:\/\/www.glass.com\/info\/wp-content\/uploads\/2018\/09\/window_frame-150x150.jpg\" class=\"dictionary-entry__img wp-post-image\" alt=\"A white window frame.\" \/>\t\t\t\t\t\t<\/div>\r\n\t\t\t\t\t\t\t\t\t\t<div class=\"dictionary-entry__details-container\">\r\n\t\t\t\t\t\t<h2 class=\"dictionary-entry__headline\"><a href=\"https:\/\/www.glass.com\/info\/glass-dictionary\/window-frames\/\">Window Frames<\/a><\/h2>\r\n\t\t\t\t\t\t<div class=\"dictionary-entry__content\">\r\n\t\t\t\t\t\t\t<p>The architectural elements that hold and support the glass in a window make up the window frame.

Wired glass was an early form of <a href=\"https:\/\/info.glass.com\/glass-dictionary\/safety-glazing\/\" target=\"_blank\" rel=\"noopener\">safety glazing<\/a>, as the wire would catch much of the glass and prevent it from falling. The glass was also frequently treated with a fire retardant to prevent the glass from breakage if exposed to high temperatures and the wire to hold it together in case it did break. This combination was an early type of <a href=\"https:\/\/info.glass.com\/glass-dictionary\/fire-rated-glass\/\" target=\"_blank\" rel=\"noopener\">fire-rated glass<\/a> and protected inhabitants from fire and possibly smoke on the opposite side of the door. While it can successfully help protect occupants from a fire or certain other situations, wired glass itself can present other hazards. When the glass surrounding the wires does break, the exposed wires can cause injury if a person physically comes in contact with them. As glass safety has evolved, the need and desire for traditional wired glass has declined and other solutions have become available.<\/p>\n\t\t\t\t\t\t<\/div>\r\n\t\t\t\t\t<\/div>\r\n\t\t\t\t\t\r\n\t\t\t\t\t<a class=\"dictionary-to-top\" href=\"#dictionary-top\">Back to top<\/a>\r\n\t\t\t\t<\/article>\r\n\r\n\t\t\t\t\t\t\t<\/div>\r\n\t\t\t\t<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"","protected":false},"author":32,"featured_media":4818,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"content-type":"","footnotes":""},"_links":{"self":[{"href":"https:\/\/www.glass.com\/info\/wp-json\/wp\/v2\/pages\/52886"}],"collection":[{"href":"https:\/\/www.glass.com\/info\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/www.glass.com\/info\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/www.glass.com\/info\/wp-json\/wp\/v2\/users\/32"}],"replies":[{"embeddable":true,"href":"https:\/\/www.glass.com\/info\/wp-json\/wp\/v2\/comments?post=52886"}],"version-history":[{"count":0,"href":"https:\/\/www.glass.com\/info\/wp-json\/wp\/v2\/pages\/52886\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.glass.com\/info\/wp-json\/wp\/v2\/media\/4818"}],"wp:attachment":[{"href":"https:\/\/www.glass.com\/info\/wp-json\/wp\/v2\/media?parent=52886"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
