But what kind of material is it actually? Glass is an amorphous solid that is thermodynamically described as a frozen, supercooled liquid. What does amorphous mean? In chemistry and physics, amorphous materials are those in which atoms are arranged regularly only in the short range, a structure referred to as short-range order. As in liquids, there is no regular atomic arrangement beyond this short range, known as long-range order. Long-range order is characteristic of crystal lattices. Due to the absence of a crystalline structure, the material appears transparent. However, through doping\u2014the addition of further materials\u2014colors can be produced and both chemical and physical properties can be altered.<\/strong><\/p>\n<p style=\"text-align: justify;\">As early as prehistoric times, obsidian, a natural volcanic glass, was used as a blade, scraper, or wedge due to its high hardness and sharp edges. The first objects made of glass were glass beads. Around 1450 BC, the first glass vessels were produced in Egypt and Mesopotamia. In Europe, the oldest windows date back to around 1000 AD.<\/p>\n<div class=\"box info  \"><div class=\"box-inner-block\"><i class=\"fa tie-shortcode-boxicon\"><\/i>\n\t\t\tEven today, this material is valued not only for its light transmission but is also used in many areas of daily life.\n\t\t\t<\/div><\/div>\n<h2><span class=\"ez-toc-section\" id=\"Structure_And_Properties\"><\/span>Structure And Properties<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p style=\"text-align: justify;\">The main component of most types of glass is silicon dioxide (SiO<sub>2<\/sub>). It is produced by melting its components, followed by rapid cooling. During solidification of the melt, crystallization nuclei are formed; however, the rapid cooling prevents the crystallization process from proceeding. As a result, no crystal lattice is formed, but rather a network structure. Bond angles and bond lengths are irregular, and the SiO<sub>2<\/sub> tetrahedra are distorted. Glass exhibits short-range order in the form of tetrahedra but lacks crystalline long-range order. The transition from melt to solid is referred to as the transformation range, which for many types of glass lies at approximately +600 \u00b0C.<\/p>\n<figure id=\"attachment_6927\" aria-describedby=\"caption-attachment-6927\" style=\"width: 448px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-6927\" title=\"Obsidian: Volcanic Rock Glass\" src=\"https:\/\/www.rct-online.de\/magazin\/wp-content\/uploads\/2021\/07\/Obsidian-Vulkanisches-Gesteinsglas.jpg\" alt=\"Obsidian Volcanic Rock Glass\" width=\"448\" height=\"300\" srcset=\"https:\/\/www.rct-online.de\/magazin\/wp-content\/uploads\/2021\/07\/Obsidian-Vulkanisches-Gesteinsglas.jpg 639w, https:\/\/www.rct-online.de\/magazin\/wp-content\/uploads\/2021\/07\/Obsidian-Vulkanisches-Gesteinsglas-300x201.jpg 300w, https:\/\/www.rct-online.de\/magazin\/wp-content\/uploads\/2021\/07\/Obsidian-Vulkanisches-Gesteinsglas-110x75.jpg 110w\" sizes=\"(max-width: 448px) 100vw, 448px\" \/><figcaption id=\"caption-attachment-6927\" class=\"wp-caption-text\">Obsidian: Volcanic Rock Glass<\/figcaption><\/figure>\n<p style=\"text-align: justify;\">Light transmission in the visible wavelength range from 380 nm to 780 nm is particularly important for many applications. By adding further materials, this property can be specifically modified. For example, the addition of cobalt oxide produces a blue coloration. Gold ruby glass, produced by adding gold purple\u2014a pigment consisting of finely dispersed gold\u2014is also well known.<\/p>\n<p style=\"text-align: justify;\">In chemistry, the excellent chemical resistance to acids, dilute alkalis, and organic compounds is of major importance.

The oxide with the highest proportion by weight after SiO<sub>2<\/sub> determines the classification. Examples of two-component glasses include alkali silicate glasses, borosilicate glasses, lead silicate glasses, and aluminosilicate glasses. Soda-lime glass, which belongs to the group of alkali-alkaline earth silicate glasses, is a representative of three-component glasses.<\/p>\n<p style=\"text-align: justify;\">The properties of inorganic, oxidic glasses can be influenced by adding further oxides: aluminum oxide increases fracture strength, boron trioxide improves chemical and thermal properties, barium oxide or lead oxide increase the refractive index, and cerium oxide is added when infrared radiation is to be absorbed.<\/p>\n<p style=\"text-align: justify;\">Representatives of organic glasses include amber, <a href=\"https:\/\/www.rct-online.de\/en\/semi-finished-products\/plates\/plastic-sheets\/30233\/plate-made-of-pmma\">acrylic glass<\/a>, and <a href=\"https:\/\/www.rct-online.de\/en\/semi-finished-products\/plates\/plastic-sheets\/30226\/plate-made-of-pc\">polycarbonate<\/a>.

Although these types of glass possess a crystal lattice and are not amorphous, they are nevertheless assigned to the group of glasses.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Classification_Of_Glass_Types_By_Application\"><\/span>Classification Of Glass Types By Application<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p style=\"text-align: justify;\">A suitable type of glass is available for almost every application. When selecting the appropriate glass type, criteria such as chemical and thermal resistance, optical transmission range, coefficient of thermal expansion, working temperature, mechanical fracture strength, and not least cost must be considered. According to their application, a distinction is made between technical glass, industrial glass, and optical glass.<\/p>\n<p><strong>Technical Glasses<\/strong><\/p>\n<p style=\"text-align: justify;\">The group of technical glasses includes apparatus or laboratory glasses. In 1881, Otto Schott (1851\u20131935) developed his &#8220;borate glass&#8221; in Jena (Germany) for optical purposes. There was also a demand in chemistry for a new type of glass. The soda-lime and lead glasses previously used were attacked by acids and alkalis and did not offer sufficient temperature resistance.<\/p>\n<div class=\"box info  \"><div class=\"box-inner-block\"><i class=\"fa tie-shortcode-boxicon\"><\/i>\n\t\t\tAfter six years of development, Otto Schott introduced borosilicate glass as laboratory glass in 1893.\n\t\t\t<\/div><\/div>\n<p style=\"text-align: justify;\">Due to its high resistance to acids, alkalis, salt solutions, and organic compounds, as well as its high resistance to thermal shock, this type is ideally suited for use in chemical laboratories. In addition to silicon dioxide, borosilicate glasses contain 7% to 13% boron trioxide. Well-known trade names for laboratory glassware include Jenaer Glas\u00ae, Duran\u00ae, and Pyrex\u00ae.<\/p>\n<figure id=\"attachment_6931\" aria-describedby=\"caption-attachment-6931\" style=\"width: 300px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-6931\" title=\"Laboratory Glassware Made Of Borosilicate Glass\" src=\"https:\/\/www.rct-online.de\/magazin\/wp-content\/uploads\/2021\/07\/Glaswaren-aus-Borosilikatglas-im-Labor.jpg\" alt=\"Laboratory Glassware Borosilicate Glass\" width=\"300\" height=\"448\" srcset=\"https:\/\/www.rct-online.de\/magazin\/wp-content\/uploads\/2021\/07\/Glaswaren-aus-Borosilikatglas-im-Labor.jpg 481w, https:\/\/www.rct-online.de\/magazin\/wp-content\/uploads\/2021\/07\/Glaswaren-aus-Borosilikatglas-im-Labor-201x300.jpg 201w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><figcaption id=\"caption-attachment-6931\" class=\"wp-caption-text\">Laboratory Glassware Made Of Borosilicate Glass<\/figcaption><\/figure>\n<p style=\"text-align: justify;\">In households, it is found in baking and casserole dishes. Furthermore, sight glass fittings, lamp envelopes, and pharmaceutical glassware such as ampoules are made of borosilicate glass.<\/p>\n<p style=\"text-align: justify;\">Other technical glasses include display panels made of borosilicate or aluminosilicate glass. Display panels with integrated switching and touch elements are used in information displays, gaming machines, vending machines, and industrial automation.<\/p>\n<p><strong>Industrial Glasses<\/strong><\/p>\n<p style=\"text-align: justify;\">The group of industrial glasses includes architectural or building glass. Depending on further processing of the melt, a distinction is made between float glass (pouring and floating), cast glass (casting and rolling), and pressed glass (casting and pressing). In construction, soda-lime silicate glass is primarily used as the base material. In addition to light transmission, fracture strength is of decisive importance for this application.<\/p>\n<div class=\"box success  \"><div class=\"box-inner-block\"><i class=\"fa tie-shortcode-boxicon\"><\/i>\n\t\t\tMechanical properties can be significantly improved through thermal tempering.\n\t\t\t<\/div><\/div>\n<p style=\"text-align: justify;\">For this purpose, the glass pane is heated to a temperature approximately 100 \u00b0C above the transformation temperature. It is then rapidly cooled by blowing cold air over the surface. The surface would now contract, but this is prevented by the still-hot core. As a result, tensile stress forms on the surface and compressive stress in the core. If the initial temperature was selected high enough, the tensile stress can be relieved. Otherwise, the occurring tensile stresses may lead to breakage of the pane.<\/p>\n<p><center><a href=\"https:\/\/www.rct-online.de\/en\/laboratory-equipment\/laboratory-containers\/measuring-beakers-and-measuring-flasks\/31211\/erlenmeyer-flask-made-of-pc\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-6923 size-full\" title=\"Erlenmeyer Flask made of PC\" src=\"https:\/\/www.rct-online.de\/magazin\/wp-content\/uploads\/2021\/07\/erlenmeyer-kolben-aus-pc.jpg\" alt=\"Erlenmeyer Flask made of PC - Glass Types\" width=\"300\" height=\"300\" srcset=\"https:\/\/www.rct-online.de\/magazin\/wp-content\/uploads\/2021\/07\/erlenmeyer-kolben-aus-pc.jpg 300w, https:\/\/www.rct-online.de\/magazin\/wp-content\/uploads\/2021\/07\/erlenmeyer-kolben-aus-pc-150x150.jpg 150w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><\/a> <a href=\"https:\/\/www.rct-online.de\/en\/laboratory-equipment\/laboratory-containers\/measuring-beakers-and-measuring-flasks\/29801\/measuring-cylinder-made-of-san-short\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-6924 size-full\" title=\"Measuring Cylinder made of SAN - short\" src=\"https:\/\/www.rct-online.de\/magazin\/wp-content\/uploads\/2021\/07\/messzylinder-aus-san-niedrig.jpg\" alt=\"Measuring Cylinder made of SAN - short - Glass Types\" width=\"300\" height=\"300\" srcset=\"https:\/\/www.rct-online.de\/magazin\/wp-content\/uploads\/2021\/07\/messzylinder-aus-san-niedrig.jpg 300w, https:\/\/www.rct-online.de\/magazin\/wp-content\/uploads\/2021\/07\/messzylinder-aus-san-niedrig-150x150.jpg 150w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><\/a><\/center><\/p>\n<p style=\"text-align: justify;\">Tempered glass exhibits significantly increased fracture strength, greater resistance to thermal shock, and shatters into small pieces with blunt edges when broken.

This category includes fused quartz, lead glass, borosilicate glass, as well as halide and chalcogenide glasses. For their use, wavelength-dependent light transmission is decisive. The wavelength range of visible light extends from 380 nm to 780 nm, while infrared radiation ranges from 780 nm to 1 mm. Light transmission ranges are approximately 170 nm to 5 \u00b5m for fused quartz, 350 nm to 2.5 \u00b5m for borosilicate glass, 200 nm to 6 \u00b5m for calcium fluoride, and 600 nm to 21 \u00b5m for zinc selenide.<\/p>\n<p style=\"text-align: justify;\">Lead glasses contain at least 18% lead(II) oxide. They are characterized by a high refractive index, high dispersion, and high density. Today, lead glass is used for shielding radiation sources in radiology and nuclear medicine, as well as for detectors in nuclear and particle physics. It is also used for decorative glassware and gemstone imitations.<\/p>\n<figure id=\"attachment_6935\" aria-describedby=\"caption-attachment-6935\" style=\"width: 400px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-6935\" title=\"Glasses Made Of Smooth Lead Glass With Etched Patterns\" src=\"https:\/\/www.rct-online.de\/magazin\/wp-content\/uploads\/2021\/07\/Glaeser-aus-glattem-Bleiglas-mit-eingeaetzten-Mustern.jpg\" alt=\"Smooth Lead Glass With Etched Patterns Glass Types\" width=\"400\" height=\"328\" srcset=\"https:\/\/www.rct-online.de\/magazin\/wp-content\/uploads\/2021\/07\/Glaeser-aus-glattem-Bleiglas-mit-eingeaetzten-Mustern.jpg 680w, https:\/\/www.rct-online.de\/magazin\/wp-content\/uploads\/2021\/07\/Glaeser-aus-glattem-Bleiglas-mit-eingeaetzten-Mustern-300x246.jpg 300w\" sizes=\"(max-width: 400px) 100vw, 400px\" \/><figcaption id=\"caption-attachment-6935\" class=\"wp-caption-text\">Glasses Made Of Smooth Lead Glass With Etched Patterns<\/figcaption><\/figure>\n<p style=\"text-align: justify;\">Due to the large number of different glass types and the wide range of possibilities in shaping and coloring, this versatile material is used extensively in many technical, medical, chemical, and everyday applications.
