How to Manufacture Glass: Glass Manufacturing Process

VIDEO ON THE TOPIC: How Glass is Made

Genevieve Mills. From heat resistant Pyrex to PVB laminated safety windshields, glass is available in many forms. Some of the materials commonly referred to as glasses are actually plastic or plastic-glass mixes, although the term glass does not explicitly indicate a particular chemical composition. The term can describe any number of hard, amorphous, inorganic, and uniform solids produced when fused molten materials are cooled fast enough to prevent crystallization.

However, the typical substances used in glass making are silicates, borates, and phosphates. Glass is an inflexible material that is formed by heating a mixture of dry solid materials until it reaches a semi-solid state, then cooling the mixture quickly to prevent it from forming the crystalline structure that most solid materials have.

As the glass cools, the atoms become locked in a disordered state similar to that of a liquid before they can form the crystalline state of a solid. As glass is neither a liquid nor a solid, but instead has the qualities of both, glass exist as a separate type of matter. Because of its strength and versatility, glass has near limitless applications. It is used extensively in construction, providing facing for most modern buildings and regular architectural glass features for most other habitable structures.

It finds diverse uses in the home, whether as cookware, television screens, or light bulbs. It is likely the single most important material in astronomy, which was originally made possible by the use of different glass lenses. In addition to its obvious uses in biological, chemical and medical laboratories test tubes, beakers, microscopes , glass also provides part of the casing for most instrumentation.

Although polycarbonate lenses have largely replaced glass in eyeglasses, glass lenses were, historically, the only means to improve vision. Even art owes a great deal to glass, as stained glass and many decorative glass objects from antiquity have survived and provided inspiration to artists for more than a thousand years. In modern industry, glass serves many biomedical and optic-related functions. It is also a necessary component in numerous aerospace and avionic devices, as well as a useful substance in semiconductor technology and electronics.

Due to its unique properties, certain types of glass are used in integrated circuits. It also provides a reinforcing material for laminated plastics. Glass beads are used in sandblasting, and glass sheets are a prerequisite of most mirror manufacturers. This article gives an understanding of the unique properties of glass, explaining the different types of glass and their makeups.

Additionally, the way glass if fabricated is explored, along with some of the various ways glass can be treated or finished after fabrication. While there are many different types of glass, and their properties vary with their chemical compositions, there are a few characteristics, most kinds of glass have in common. Despite its fragile reputation, glass is mechanically strong. Surface imperfections weaken glass, but there are processes to minimize flaws and strengthen it.

Glass is a hard material that resists scratches and abrasions to some level. Glass is generally chemically resistant against most industrial and food acids, and its resistance to other chemicals varies.

It is elastic and yields under stress before bending back to its original shape. Of course, glass has a breaking point that varies by type. Glass is thermal-shock resistant, meaning it can withstand sudden temperature changes well, and is able to endure intense heat and cold, to various degrees. It is heat-absorbent, retaining heat instead of conducting it, and absorbs heat better than metal.

Glass can reflect, bend, transmit, and absorb light with great accuracy, and is highly valued for its optical properties. It strongly resists electrical current and stores electricity well.

Glass is divided into type based on its chemical composition. These are some of the more common types. Soda-lime glass , also known as soda-lime-silica glass or window glass, is the most common and least expensive type of glass.

The soda lowers the temperature at which the silica melts, while the lime stabilizes the silica. It is a softer glass, which is an asset for fabrication via cutting, but this does mean it is less scratch resistant than other types of glass, such as borosilicate and fused quartz. Soda-lime glass is often chemically strengthened to increase its strength, or it can be tempered to increase its thermal shock resistance and strength.

As its nickname suggests, it is commonly used in windows. Soda-lime has a wide range of applications.

It has also been called flint glass since the original formula from the s used calcined flint as a source of silica, but now flint is no longer used in its creation. It is a softer glass, making it easier to cut into designs that show off its high refractive index.

It cannot withstand high temperatures or sudden changes in temperature. Because lead glass is refractive and more expensive than soda-lime glass, it used to be commonly used for decorative glass dishware. However, since the dangers of ingesting lead are now well-known, today lead glass is used mainly for electrical applications because of its electrical insulating properties and lower melting temperature.

The low melting temperature is desirable for heat-sealing so it can be sealed around electronics sensitive to higher temperatures. It is also used for shielding applications to protect against x-rays and gamma rays in medical, technical, and research work, and for optical glasses because of its refractive index.

Durable and heat resistant, borosilicate glass is the material of choice for a wide range of applications, from cookware to laboratory use. Creating borosilicate glass requires higher temperatures than those necessary for the production of regular glass, although this also accounts for its higher heat resistance.

It also faces far less material stress than regular glass due to its lower thermal expansion coefficient, which also adds to its exceptional performance at high temperatures. Additionally, borosilicate glass is far more durable than traditional glass and can withstand accidents that would break other glassware. Even when it does crack, it typically performs better, as it rarely shatters. Borosilicate glass is often used for scientific and medical laboratories since it offers excellent chemical resistance in addition to its other useful qualities.

Everything from test tubes, rods, and beakers to graduated cylinders, pipettes, and stopper attachments are produced from borosilicate and used in laboratories around the world. Although borosilicate glass offers exceptional acid resistance, it is less resistant to a range of alkalis, and occasionally other materials should be considered.

Borosilicate glass is also used in certain optics such as mirrors because it retains shape well throughout changes in temperature. Other uses include the strengthening of various plastic compounds and in various gages and protective glass surfaces. The main distinction of borosilicate glass from traditional glass is the substitution of boron oxide for soda and lime in the manufacturing process. Borosilicate glass must contain at least five percent boron oxide, which helps bind the silicate and aluminum oxide and sodium oxide.

Aluminosilicate glass contains aluminum oxide. It has comparable properties to borosilicate glass but is more heat resistant, tolerating temperatures up to o Celsius, and has a better chemical resistance. The two main kinds of aluminosilicate glass are alkaline earth aluminosilicate glass and alkali aluminosilicate glass. Alkaline earth aluminosilicate glasses have a very high softening point and are typically used for glass bulbs for halogen lamps, high-temperature thermometers, and can be coated in an electrically conductive film and used for resistors in electronic circuitry.

The high alkali content of alkali aluminosilicate glasses improves their surface compressive strength. They are also very hard and scratch resistant. They are commonly used for touch displays, such as smartphone screens, and for solar cells cover glass and laminated safety glass. High silica glass has a very low thermal expansion, very good chemical durability, optical properties, and mechanical properties, but the extremely high processing temperatures is a limiting factor in the production and application on a larger scale.

As technology improves, the ability to reach a greater purity of high silica glass has improved, making it possible to fabricate higher and higher qualities of glass. Fused quartz glass , also called fused-silica glass or vitreous-silica glass, is fabricated by purifying and melting down naturally occurring crystalline silica, found in sand or rock crystal, either with electrical or flame fusion. The resulting glass is highly transparent, even to ultraviolet and infrared light, and weather and shock resistant.

It is very difficult to fabricate, as fusion occurs at approximately o C, so it is very expensive. Because of this resistance, fused quartz glass is often used for aerospace applications, specifically the windows of manned spacecraft.

While some fabrication variations exist in creating different types of glass, the following outlines the basic process used to create the more common types of glass, such as soda-lime. The ingredients that make up glass vary depending on the type of glass. The main component of glass, called former, must be heated to a very high temperature to become viscous. The most common former is silicon dioxide, found in sand. The former is mixed with a flux, which helps it to melt at a lower temperature.

Common fluxes are soda ash and potash. A stabilizer is also used to keep the glass from dissolving or forming unwanted crystal impurities. A common stabilizer is calcium oxide, from limestone.

These dry ingredients are mixed together in a batch. A furnace melts the batch to form a liquid compound. Cullet, which is made up of broken glass, is added to the batch to help it melt. If colored glass is being fabricated, a metallic oxide is added to the batch. Iron colors glass green, copper turns it light blue, cobalt a dark blue, gold a deep red.

Low-iron glass is recommended when coloring glass any color besides green. In small amounts, manganese dioxide is used to decolorize glass, but in large amounts, it colors glass purple, or with a higher amount, black.

The slow and even cooling process is called annealing. Glass must be cooled evenly, because if one area stays hotter longer it becomes thicker, and the different levels of thickness results in stress on the piece of glass. An improperly-annealed piece of glass is more likely to crack. Next, annealed glass is cut down to the desired dimensions.

This is usually done with Computer Numerical Control machines, or CNC machines, which are capable of extremely precise operations. CNC machines operate according to specific CAM and CAD software programs, which enable them to machine any number of workpieces with identical precision.

They are also able to perform a wide range of machining tasks normally accomplished by specialized equipment: they can cut curves and straight lines, drill holes, and grind grooves. The CNC machines used in glass fabricating use distinctive tooling, including diamond abrasive tooling, diamond points, and carbide wheels, to achieve better accuracy and glass working capabilities. After the glass is cut and shaped, manufacturers usually perform some glass polishing, laminating, and other finishing services.

Polished mirrors and lenses make up a significant part of the glass fabrication market. These items generally demand extreme precision, and surface tolerances must be exact in order for components to function as desired.

What is Glass? Glass is a substance that has certain properties, primarily fragility and stiffness, which makes it similar to solids, but a disordered structure gives it a liquid qualification. Glass has no thermal and electrical conductivity and does not react with most of the known chemical compounds.

Glass production involves two main methods — the float glass process that produces sheet glass, and glassblowing that produces bottles and other containers. Broadly, modern glass container factories are three-part operations: the batch house , the hot end , and the cold end. The batch house handles the raw materials; the hot end handles the manufacture proper—the forehearth, forming machines, and annealing ovens; and the cold end handles the product-inspection and packaging equipment. Batch processing is one of the initial steps of the glass-making process. The batch house simply houses the raw materials in large silos fed by truck or railcar and holds anywhere from 1—5 days of material. Whether automated or manual, the batch house measures, assembles, mixes, and delivers the glass raw material recipe batch via an array of chutes, conveyors, and scales to the furnace.

It provides solutions to all problems pertaining to houses right from concept to completion. Glass is an amorphous inorganic, homogeneous transparent or translucent material which can be molded into any shape. Based on the type of glass, its raw materials are collected and different compositions are sent to the manufacturing process. Following are the raw materials for different types of glass. Batch preparation is one of the first phases of the manufacturing process of glass, which involves weighing fine ground raw materials. This process includes formers, fluxes, stabilizers and sometimes colorants according to recipe required for the final product of the glass. The fine raw materials are subsequently mixed with each other to achieve a homogenous composition and then they are transferred into the melting furnace.

Understanding Glass - Types, Properties and Fabrication

This handbook provides comprehensive treatment of the current state of glass science from the leading experts in the field. Opening with an enlightening contribution on the history of glass, the volume is then divided into eight parts. The first part covers fundamental properties, from the current understanding of the thermodynamics of the amorphous state, kinetics, and linear and nonlinear optical properties through colors, photosensitivity, and chemical durability. The second part provides dedicated chapters on each individual glass type, covering traditional systems like silicates and other oxide systems, as well as novel hybrid amorphous materials and spin glasses.

The procedure adopted in the manufacture of glass may broadly be divided into the following five stages: 1 Collection of Raw Materials 2 Preparation of Batch 3 Melting in Furnace 4 Fabrication 5 Annealing. Depending upon the type of glass to be manufactured, suitable raw materials are collected. Table shows the raw materials required for each type of glass. In addition to the raw materials, the cullet and decolourisers are also added for each type of glass. The cullet indicates waste glass or pieces of broken glass. They increase the fusibility of glass and prevent loss of alkali by volatisation during the reaction in forming new glass. They also reduce the cost. The raw materials generally contain traces of the iron compounds. The ferrous oxide imparts a green colour to glass and ferric oxide imparts a very light yellow tint. To avoid such effects, the decolourisers are added. The raw materials, cullet and decolouriser are finely powdered in grinding machines.

Если бы ему захотелось, он мог бы навечно стереть из памяти все свои предыдущие воплощения -- в тот миг, когда он снова войдет в Зал Творения, чтобы уснуть до поры, пока город снова не призовет.

Но это была бы своего рода смерть, а к ней он еще не был готов.

Так же, как и. Они попытались открыть этот купол. Он указал на противоположную сторону кратера, на гладкую, по-прежнему без единой отметины оболочку, внутри которой отбывшие властители этого мира запечатали свои сокровища.

Мы видели, как хаос пирует среди звезд, и тяготели к миру и стабильности. А из этого со всей непреложностью следовало, что Диаспар должен быть закрыт, с тем чтобы ничто извне не могло в него проникнуть.

Мы создали город, который вам так хорошо известен, и сфабриковали фальшивое прошлое, чтобы скрыть от самих себя нашу слабость. О, мы были не первыми, кто прибегнул к такому способу.

А -- Мы не готовы уйти к звездам, и пройдет очень много времени, прежде чем мы снова примем их вызов. Я все думал -- что мне делать с этим кораблем.
