From old County history : What are known as the Dunbarton Glass Works are situated on the Erie canal about four miles northerly from Durhamville. This was also at one time an extensive establishment, employing over fifty hands and turning out 30,000 boxes of glass annually. It went under control of the United Glass Company and was closed down in 1890. There is a post office, but no business at Dunbarton. Glass is a non-crystalline amorphous solid that is often transparent and has widespread practical, technological, and decorative usage in, for example, window panes, tableware, and optoelectronics.

The most familiar, and historically the oldest, types of glass are "silicate glasses" based on the chemical compound silica (silicon dioxide, or quartz), the primary constituent of sand. The term glass, in popular usage, is often used to refer only to this type of material, which is familiar from use as window glass and in glass bottles.

Of the many silica-based glasses that exist, ordinary glazing and container glass is formed from a specific type called soda-lime glass, composed of approximately 75% silicon dioxide (SiO2), sodium oxide (Na2O) from sodium carbonate (Na2CO3), calcium oxide, also called lime (CaO), and several minor additives. Many applications of silicate glasses derive from their optical transparency, giving rise to their primary use as window panes. Glass will transmit, reflect and refract light; these qualities can be enhanced by cutting and polishing to make optical lenses, prisms, fine glassware, and optical fibers for high speed data transmission by light. Glass can be coloured by adding metallic salts, and can also be painted and printed with vitreous enamels.

These qualities have led to the extensive use of glass in the manufacture of art objects and in particular, stained glass windows. Although brittle, silicate glass is extremely durable, and many examples of glass fragments exist from early glass-making cultures.

Because glass can be formed or moulded into any shape, it has been traditionally used for vessels: bowls, vases, bottles, jars and drinking glasses. In its most solid forms it has also been used for paperweights, marbles, and beads. When extruded as glass fiber and matted as glass wool in a way to trap air, it becomes a thermal insulating material, and when these glass fibers are embedded into an organic polymer plastic, they are a key structural reinforcement part of the composite material fiberglass. Some objects historically were so commonly made of silicate glass that they are simply called by the name of the material, such as drinking glasses and eyeglasses. Scientifically, the term "glass" is often defined in a broader sense, encompassing every solid that possesses a non-crystalline (that is, amorphous) structure at the atomic scale and that exhibits a glass transition when heated towards the liquid state.

Porcelains and many polymer thermoplastics familiar from everyday use are glasses. These sorts of glasses can be made of quite different kinds of materials than silica: metallic alloys, ionic melts, aqueous solutions, molecular liquids, and polymers.

For many applications, like glass bottles or eyewear, polymer glasses (acrylic glass, polycarbonate or polyethylene terephthalate) are a lighter alternative than traditional glass. Silica (SiO2) is a common fundamental constituent of glass. [1] In nature, vitrification of quartz occurs when lightning strikes sand, forming hollow, branching rootlike structures called fulgurites. Fused quartz is a glass made from chemically-pure silica. It has excellent resistance to thermal shock, being able to survive immersion in water while red hot.

However, its high melting temperature (1723 °C) and viscosity make it difficult to work with. [3] Normally, other substances are added to simplify processing. One is sodium carbonate (Na2CO3, "soda"), which lowers the glass-transition temperature.

The soda makes the glass water-soluble, which is usually undesirable, so lime (CaO, calcium oxide, generally obtained from limestone), some magnesium oxide (MgO) and aluminium oxide (Al2O3) are added to provide for a better chemical durability. The resulting glass contains about 70 to 74% silica by weight and is called a soda-lime glass. [4] Soda-lime glasses account for about 90% of manufactured glass. Most common glass contains other ingredients to change its properties.

Lead glass or flint glass is more "brilliant" because the increased refractive index causes noticeably more specular reflection and increased optical dispersion. Adding barium also increases the refractive index. Thorium oxide gives glass a high refractive index and low dispersion and was formerly used in producing high-quality lenses, but due to its radioactivity has been replaced by lanthanum oxide in modern eyeglasses.

[7] Iron can be incorporated into glass to absorb infrared radiation, for example in heat-absorbing filters for movie projectors, while cerium(IV) oxide can be used for glass that absorbs ultraviolet wavelengths. The following is a list of the more common types of silicate glasses and their ingredients, properties, and applications. Fused quartz, [9] also called fused-silica glass, [10] vitreous-silica glass: silica (SiO2) in vitreous, or glass, form i.

Its molecules are disordered and random, without crystalline structure. It has very low thermal expansion, is very hard, and resists high temperatures (10001500 °C). It is also the most resistant against weathering (caused in other glasses by alkali ions leaching out of the glass, while staining it).

Fused quartz is used for high-temperature applications such as furnace tubes, lighting tubes, melting crucibles, etc. Soda-lime-silica glass, window glass:[12] silica + sodium oxide (Na2O) + lime (CaO) + magnesia (MgO) + alumina (Al2O3). [13][14] Is transparent, [15] easily formed and most suitable for window glass (see flat glass). [16] It has a high thermal expansion and poor resistance to heat[15] (500600 °C). [11] It is used for windows, some low-temperature incandescent light bulbs, and tableware.

[17] Container glass is a soda-lime glass that is a slight variation on flat glass, which uses more alumina and calcium, and less sodium and magnesium, which are more water-soluble. This makes it less susceptible to water erosion. Sodium borosilicate glass, Pyrex: silica + boron trioxide (B2O3) + soda (Na2O) + alumina (Al2O3). [18] Stands heat expansion much better than window glass. [10] Used for chemical glassware, cooking glass, car head lamps, etc.

Pyrex, Duran have as main constituents silica and boron trioxide. They have fairly low coefficients of thermal expansion (7740 Pyrex CTE is 3.25×106/°C[19] as compared to about 9×106/°C for a typical soda-lime glass[20]), making them more dimensionally stable. The lower coefficient of thermal expansion (CTE) also makes them less subject to stress caused by thermal expansion, thus less vulnerable to cracking from thermal shock. They are commonly used for reagent bottles, optical components and household cookware. Lead-oxide glass, crystal glass, [11] lead glass:[21] silica + lead oxide (PbO) + potassium oxide (K2O) + soda (Na2O) + zinc oxide (ZnO) + alumina.

Because of its high density (resulting in a high electron density), it has a high refractive index, making the look of glassware more brilliant[22] (called "crystal", though of course it is a glass and not a crystal). It also has a high elasticity, making glassware "ring". It is also more workable in the factory, but cannot stand heating very well. [11] This kind of glass is also more fragile than other glasses[23] and is easier to cut. Aluminosilicate glass: silica + alumina + lime + magnesia[24] + barium oxide (BaO)[11] + boric oxide (B2O3). [24] Extensively used for fiberglass, [24] used for making glass-reinforced plastics boats, fishing rods, etc.

And for halogen bulb glass. [11] Aluminosilicate glasses are also resistant to weathering and water erosion.

Germanium-oxide glass: alumina + germanium dioxide (GeO2). Extremely clear glass, used for fiber-optic waveguides in communication networks. [26] Light loses only 5% of its intensity through 1 km of glass fiber. Another common glass ingredient is crushed alkali glass or'cullet' ready for recycled glass. The recycled glass saves on raw materials and energy.

Impurities in the cullet can lead to product and equipment failure. Fining agents such as sodium sulfate, sodium chloride, or antimony oxide may be added to reduce the number of air bubbles in the glass mixture. [4] Glass batch calculation is the method by which the correct raw material mixture is determined to achieve the desired glass composition. The history of glass-making can be traced back to 3500 BC Asia in Mesopotamia. However, they may have been producing second-rate copies of glass objects from Egypt, where this complex craft actually originated.

[1] Other archaeological evidence suggests that the first true glass was made in coastal north Syria, Mesopotamia or Egypt. [2] The earliest known glass objects, of the mid second millennium BC, were beads, perhaps initially created as the accidental by-products of metal-working (slags) or during the production of faience, a pre-glass vitreous material made by a process similar to glazing. [n 1] Glass products remained a luxury until the disasters that overtook the late Bronze Age civilizations seemingly brought glass-making to a halt. Development of glass technology in India may have begun in 1730 BC. [3] In ancient China, though, glass-making seems to have had a late start compared to ceramics and metal work. From across the former Roman Empire archaeologists have recovered glass objects that were used in domestic, industrial and funerary contexts.

Anglo-Saxon glass has been found across England during archaeological excavations of both settlement and cemetery sites. Glass in the Anglo-Saxon period was used in the manufacture of a range of objects including vessels, beads, windows and was even used in jewelry. Ancient Greek glass amphora from the Hellenistic period. Naturally occurring glass, especially the volcanic glass obsidian, has been used by many Stone Age societies across the globe for the production of sharp cutting tools and, due to its limited source areas, was extensively traded. But in general, archaeological evidence suggests that the first true glass was made in coastal north Syria, Mesopotamia or ancient Egypt.

[2] Because of Egypt's favorable environment for preservation, the majority of well-studied early glass is found there, although some of this is likely to have been imported. The earliest known glass objects, of the mid third millennium BC, were beads, perhaps initially created as accidental by-products of metal-working (slags) or during the production of faience, a pre-glass vitreous material made by a process similar to glazing. During the Late Bronze Age in Egypt e. The Ahhotep "Treasure" and Western Asia e. Megiddo[4] there was a rapid growth in glass-making technology.

Archaeological finds from this period include colored glass ingots, vessels (often colored and shaped in imitation of highly prized hardstone carvings in semi-precious stones) and the ubiquitous beads. The alkali of Syrian and Egyptian glass was soda ash, sodium carbonate, which can be extracted from the ashes of many plants, notably halophile seashore plants: (see saltwort). The earliest vessels were'core-formed', produced by winding a ductile rope of glass round a shaped core of sand and clay over a metal rod, then fusing it with repeated reheatings.

Threads of thin glass of different colors made with admixtures of oxides were subsequently wound around these to create patterns, which could be drawn into festoons by using metal raking tools. The vessel would then be rolled smooth ('marvered') on a slab in order to press the decorative threads into its body. Handles and feet were applied separately. The rod was subsequently allowed to cool as the glass slowly annealed and was eventually removed from the center of the vessel, after which the core material was scraped out.

Glass shapes for inlays were also often created in moulds. Much early glass production, however, relied on grinding techniques borrowed from stone working. This meant that the glass was ground and carved in a cold state. By the 15th century BC extensive glass production was occurring in Western Asia, Crete and Egypt and the Mycenaean Greek term , ku-wa-no-wo-ko-i, meaning "workers of lapis lazuli and glass" (written in Linear b syllabic script) is attested.

[6][7][8][n 2][n 3] It is thought the techniques and recipes required for the initial fusing of glass from raw materials was a closely guarded technological secret reserved for the large palace industries of powerful states. Glass workers in other areas therefore relied on imports of pre-formed glass, often in the form of cast ingots such as those found on the Ulu Burun shipwreck off the coast of modern Turkey. An early 18th-century goblet with coats of arms in the District Museum in Tarnów is one of the highest (54.3 cm, 21.4 in) preserved examples of artistry of less known Lubaczów glass manufacturing factory.

[11] The goblet was almost entirely covered with a pattern of so-called carp scales and hand-engraved decoration. Glass remained a luxury material, and the disasters that overtook Late Bronze Age civilizations seem to have brought glass-making to a halt.

It picked up again in its former sites, in Syria and Cyprus, in the 9th century BC, when the techniques for making colorless glass were discovered. The first glassmaking "manual" dates back to ca. Instructions on how to make glass are contained in cuneiform tablets discovered in the library of the Assyrian king Ashurbanipal. In Egypt glass-making did not revive until it was reintroduced in Ptolemaic Alexandria. Core-formed vessels and beads were still widely produced, but other techniques came to the fore with experimentation and technological advancements.

During the Hellenistic period many new techniques of glass production were introduced and glass began to be used to make larger pieces, notably table wares. Techniques developed during this period include'slumping' viscous (but not fully molten) glass over a mould in order to form a dish and'millefiori' (meaning'thousand flowers') technique, where canes of multi-colored glass were sliced and the slices arranged together and fused in a mould to create a mosaic-like effect. It was also during this period that colorless or decolored glass began to be prized and methods for achieving this effect were investigated more fully. According to Pliny the Elder, Phoenician traders were the first to stumble upon glass manufacturing techniques at the site of the Belus River. Georgius Agricola, in De re metallica, reported a traditional serendipitous "discovery" tale of familiar type. This account is more a reflection of Roman experience of glass production, however, as white silica sand from this area was used in the production of glass within the Roman Empire due to its high purity levels. During the 1st century BC glass blowing was discovered on the Syro-Judean coast, revolutionizing the industry. Glass vessels were now inexpensive compared to pottery vessels. A growth of the use of glass products occurred throughout the Roman world. [citation needed] Glass became the Roman plastic, and glass containers produced in Alexandria[citation needed] spread throughout the Roman Empire. With the discovery of clear glass (through the introduction of manganese dioxide), by glass blowers in Alexandria circa 100 AD, the Romans began to use glass for architectural purposes. Cast glass windows, albeit with poor optical qualities, began to appear in the most important buildings in Rome and the most luxurious villas of Herculaneum and Pompeii. Over the next 1,000 years, glass making and working continued and spread through southern Europe and beyond.

Indian development of glass technology in South Asia may have begun in 1730 BC. [3] Evidence of this culture includes a red-brown glass bead along with a hoard of beads dating to that period, making it the earliest attested glass from the Indus Valley locations. [3] Glass discovered from later sites dating from 600300 BC displays common colors.

Chalcolithic evidence of glass has been found in Hastinapur, India. [14] Some of the texts which mention glass in India are the Shatapatha Brahmana and Vinaya Pitaka. [14] However, the first unmistakable evidence in large quantities, dating from the 3rd century BC, has been uncovered from the archaeological site in Takshashila, Pakistan, with bangles, beads, small vessels, and tiles discovered in quantity. By the 1st century AD, glass was being used for ornaments and casing in South Asia. [14] Contact with the Greco-Roman world added newer techniques, and Indians artisans mastered several techniques of glass molding, decorating and coloring by the succeeding centuries.

[14] The Satavahana period of India also produced short cylinders of composite glass, including those displaying a lemon yellow matrix covered with green glass. Main articles: Ancient Chinese glass and Peking glass. Blue glass plaques found in the Mausoleum of the Nanyue King, dating from late 2nd century BC. In Chinese history, glass played a peripheral role in the arts and crafts, when compared to ceramics and metal work. [16] The limited archaeological distribution and use of glass objects are evidence of the rarity of the material.

Literary sources date the first manufacture of glass to the 5th century AD. [17] However, the earliest archaeological evidence for glass manufacture in China comes from the Warring States period (475 BC to 221 BC). Chinese learned to manufacture glass comparably later than the Mesopotamians, Egyptians and Indians. [18] Imported glass objects first reached China during the late Spring and Autumn period early Warring States period (early 5th century BC), in the form of polychrome eye beads. [19] These imports created the impetus for the production of indigenous glass beads.

During the Han period (206 BC to 220 AD) the use of glass diversified. The introduction of glass casting in this period encouraged the production of moulded objects, such as bi disks and other ritual objects. [18] The Chinese glass objects from the Warring States period and Han Dynasty vary greatly in chemical composition from the imported glass objects. The glasses from this period contain high levels of barium oxide (BaO) and lead, distinguishing them from the soda-lime-silica glasses of Western Asia and Mesopotamia.

[20] At the end of the Han Dynasty (AD 220), the lead-barium glass tradition declined, with glass production only resuming during the 4th and 5th centuries AD. Roman glass production developed from Hellenistic technical traditions, initially concentrating on the production of intensely colored cast glass vessels. Glass objects have been recovered across the Roman Empire[22] in domestic, funerary[23] and industrial contexts. [24] Glass was used primarily for the production of vessels, although mosaic tiles and window glass were also produced. However, during the 1st century AD, the industry underwent rapid technical growth that saw the introduction of glass blowing and the dominance of colorless or aqua glasses.

Production of raw glass was undertaken in geographically separate locations to the working of glass into finished vessels, [25][26] and by the end of the 1st century AD large scale manufacturing, primarily in Alexandria, [27] resulted in the establishment of glass as a commonly available material in the Roman world. Islamic glass continued the achievements of pre-Islamic cultures, especially the Sasanian glass of Persia.

The Arab poet al-Buhturi (820897) described the clarity of such glass, Its color hides the glass as if it is standing in it without a container. [28] In the 8th century, the Persian-Arab chemist Jbir ibn Hayyn (Geber) described 46 recipes for producing colored glass in Kitab al-Durra al-Maknuna (The Book of the Hidden Pearl), in addition to 12 recipes inserted by al-Marrakishi in a later edition of the book. [29] By the 11th century, clear glass mirrors were being produced in Arab Islamic Spain. A 16th-century stained glass window. The Roman tradition of very fine glassmaking did not continue in the Middle Ages, and Anglo-Saxon glass and other regional traditions were mainly functional pieces, mostly somewhat crude forest glass.

The claw beaker was popular as a relatively easy to make but impressive vessel that exploited the unique potential of glass. Only at the end of the period did European glass vessels once again become very fine in quality, imitating those imported from the Islamic world.

Glass objects from the 7th and 8th centuries have been found on the island of Torcello near Venice. These form an important link between Roman times and the later importance of that city in the production of the material.

Around 1000 AD, an important technical breakthrough was made in Northern Europe when soda glass, produced from white pebbles and burnt vegetation was replaced by glass made from a much more readily available material: potash obtained from wood ashes. From this point on, northern glass differed significantly from that made in the Mediterranean area, where soda remained in common use. Until the 12th century, stained glass glass to which metallic or other impurities had been added for coloring was not widely used, but it rapidly became an important medium for Romanesque art and especially Gothic art. Almost all survivals are in church buildings, but it was also used in grand secular buildings. The 11th century saw the emergence in Germany of new ways of making sheet glass by blowing spheres. The spheres were swung out to form cylinders and then cut while still hot, after which the sheets were flattened. This technique was perfected in 13th century Venice. The Crown glass process was used up to the mid-19th century. In this process, the glassblower would spin approximately 9 pounds (4 kg) of molten glass at the end of a rod until it flattened into a disk approximately 5 feet (1.5 m) in diameter. The disk would then be cut into panes. Domestic glass vessels in late medieval Northern Europe are known as Forest glass. [31] In the 5th century AD with the Roman departure from Britain, there were also considerable changes in the usage of glass.

[32] Excavation of Romano-British sites have revealed plentiful amounts of glass but, in contrast, the amount recovered from 5th century and later Anglo-Saxon sites is minuscule. The majority of complete vessels and assemblages of beads come from the excavations of early Anglo-Saxon cemeteries, but a change in burial rites in the late 7th century affected the recovery of glass, as Christian Anglo-Saxons were buried with fewer grave goods, and glass is rarely found. From the late 7th century onwards, window glass is found more frequently. This is directly related to the introduction of Christianity and the construction of churches and monasteries. [32][33] There are a few Anglo-Saxon ecclesiastical[34] literary sources that mention the production and use of glass, although these relate to window glass used in ecclesiastical buildings.

[32][33][35] Glass was also used by the Anglo-Saxons in their jewelry, both as enamel or as cut glass insets. Main articles: Murano glass and Venetian glass.

The center for luxury Italian glassmaking from the 14th century was the island of Murano, which developed many new techniques and became the center of a lucrative export trade in dinnerware, mirrors, and other items. What made Venetian Murano glass significantly different was that the local quartz pebbles were almost pure silica, and were ground into a fine clear sand that was combined with soda ash obtained from the Levant, for which the Venetians held the sole monopoly. The clearest and finest glass is tinted in two ways: firstly, a natural coloring agent is ground and melted with the glass. Many of these coloring agents still exist today; for a list of coloring agents, see below.

Black glass was called obsidianus after obsidian stone. A second method is apparently to produce a black glass which, when held to the light, will show the true color that this glass will give to another glass when used as a dye. The Venetian ability to produce this superior form of glass resulted in a trade advantage over other glass producing lands.

Muranos reputation as a center for glassmaking was born when the Venetian Republic, fearing fire might burn down the citys mostly wood buildings, ordered glassmakers to move their foundries to Murano in 1291. Murano's glassmakers were soon the islands most prominent citizens. Glassmakers were not allowed to leave the Republic. Many took a risk and set up glass furnaces in surrounding cities and as far afield as England and the Netherlands.

Bohemian glass, or Bohemia crystal, is a decorative glass produced in regions of Bohemia and Silesia, now in the current state of the Czech Republic, since the 13th century. [39] Oldest archaeology excavations of glass-making sites date to around 1250 and are located in the Lusatian Mountains of Northern Bohemia. Most notable sites of glass-making throughout the ages are Skalice (German: Langenau), Kamenický enov (German: Steinschönau) and Nový Bor (German: Haida). Both Nový Bor and Kamenický enov have their own Glass Museums with many items dating since around 1600. It was especially outstanding in its manufacture of glass in high Baroque style from 1685 to 1750.

In the 17th century, Caspar Lehmann, gem cutter to Emperor Rudolf II in Prague, adapted to glass the technique of gem engraving with copper and bronze wheels. Examples of Ravenscroft's glass. A very important advance in glass manufacture was the technique of adding lead oxide to the molten glass; this improved the appearance of the glass and made it easier to melt using sea-coal as a furnace fuel. This technique also increased the "working period" of the glass, making it easier to manipulate.

The process was first discovered by George Ravenscroft in 1674, who was the first to produce clear lead crystal glassware on an industrial scale. Ravenscroft had the cultural and financial resources necessary to revolutionise the glass trade, allowing England to overtake Venice as the centre of the glass industry in the eighteenth and nineteenth centuries.

Seeking to find an alternative to Venetian cristallo, he used flint as a silica source, but his glasses tended to crizzle, developing a network of small cracks destroying its transparency. This was eventually overcome by replacing some of the potash flux with lead oxide to the melt. He was granted a protective patent in 1673, where production and refinement moved from his glasshouse on the Savoy to the seclusion of Henley-on-Thames. Rather than drastically reduce the lead content of their glass, manufacturers responded by creating highly decorated, smaller, more delicate forms, often with hollow stems, known to collectors today as Excise glasses.

Evidence of the use of the blown plate glass method dates back to 1620 in London and was used for mirrors and coach plates. Louis Lucas de Nehou and A. Thevart perfected the process of casting Polished plate glass in 1688 in France.

Prior to this invention, mirror plates, made from blown "sheet" glass, had been limited in size. De Nehou's process of rolling molten glass poured on an iron table rendered the manufacture of very large plates possible. [43] This method of production was adopted by the English in 1773 at Ravenhead.

The polishing process was industrialized around 1800 with the adoption of a steam engine to carry out the grinding and polishing of the cast glass. The façade of the Crystal Palace, one of the first buildings to use glass as a main material for construction. The use of glass as a building material was heralded by The Crystal Palace of 1851, built by Joseph Paxton to house the Great Exhibition.

Paxton's revolutionary new building inspired the public use of glass as a material for domestic and horticultural architecture. In 1832, the British Crown Glass Company (later Chance Brothers) became the first company to adopt the cylinder method to produce sheet glass with the expertise of Georges Bontemps, a famous French glassmaker. [n 4] This glass was produced by blowing long cylinders of glass, which were then cut along the length and then flattened onto a cast-iron table, before being annealed. Plate glass involves the glass being ladled onto a cast-iron bed, where it is rolled into a sheet with an iron roller. The sheet, still soft, is pushed into the open mouth of an annealing tunnel or temperature-controlled oven called a lehr, down which it was carried by a system of rollers. [44] James Hartley introduced the Rolled Plate method in 1847. This allowed a ribbed finish and was often used for extensive glass roofs such as within railway stations.

An early advance in automating glass manufacturing was patented in 1848 by the engineer Henry Bessemer. His system produced a continuous ribbon of flat glass by forming the ribbon between rollers.

This was an expensive process, as the surfaces of the glass needed polishing and was later abandoned by its sponsor, Robert Lucas Chance of Chance Brothers, as unviable. Bessemer also introduced an early form of "Float Glass" in 1843, which involved pouring glass onto liquid tin. In 1887, the mass production of glass was developed by the firm Ashley in Castleford, Yorkshire.

This semi-automatic process used machines that were capable of producing 200 standardized bottles per hour, many times quicker than the traditional methods of manufacture. [45] Chance Brothers also introduced the machine rolled patterned glass method in 1888. Pilkington's factory, where the float glass process was developed in the 1950s. In 1898, Pilkington invented Wired Cast glass, where the glass incorporates a strong steel-wire mesh for safety and security.

This was commonly given the misnomer "Georgian Wired Glass" but it greatly post-dates the Georgian era. [47] The Machine Drawn Cylinder technique was invented in the USA and was the first mechanical method for the drawing of window glass. It was manufactured under licence in the UK by Pilkington from 1910 onwards.

In 1938, the polished plate process was improved by Pilkington which incorporated a double grinding process to give an improved quality to the finish. Between 1953 and 1957, Sir Alastair Pilkington and Kenneth Bickerstaff of the UK's Pilkington Brothers developed the revolutionary float glass process, the first successful commercial application for forming a continuous ribbon of glass using a molten tin bath on which the molten glass flows unhindered under the influence of gravity.

[48] This method gave the sheet uniform thickness and very flat surfaces. Modern windows are made from float glass.

Most float glass is soda-lime glass, but relatively minor quantities of specialty borosilicate[49] and flat panel display glass are also produced using the float glass process. The success of this process lay in the careful balance of the volume of glass fed onto the bath, where it was flattened by its own weight. [50] Full scale profitable sales of float glass were first achieved in 1960. Nearby towns in Oneida County.
