Bessemer's version was an expensive process, but with the efficiency of the Pilkington method, Sir Alastair was able to achieve profitable full-scale sales of float glass by 1960. Process of Manufacturing Float Glass. As the most widely used form of glass in today's world, it is essential to know about the manufacturing process of float glass.
The float glass process 3 Sheet or window glass production was first mechanized on a large scale in the early part of this century. In 1903, the American Window Glass Company developed a method for the mechanical blowing of cylinders many times larger than hand blown cylinders. This drawn cylinder process drew cylinders up to 13.4 m long and 1 m in

Glass Manufacturing Processes Glass Production involves two main methods: • Float glass process • Glassblowing Float Glass Process Float glass process is used to produce glass sheets of uniform thickness and a high degree of flatness precision. It is also known as the Pilkington process, as it was invented by Sir Alastair Pilkington in 1952.
Float makes glass of near optical quality. Several processes – melting, refining, homogenising – take place simultaneously in the 2,000 tonnes of molten glass in the furnace. They occur in separate zones in a complex glass flow driven by high temperatures.
The process, originally able to make only 6mm thick glass, now makes it as thin as 0.4 mm and as thick as 25 mm. Molten glass, at approximately 1000°C, is poured continuously from a furnace onto a shallow bath of molten tin. It floats on the tin, spreads out and forms a level surface.
This floating process, which reached its peak in 1959, revolutionised glass production methods. Until this float process was developed, glass panes were produced by drawing or moulding molten glass, and then polishing it. This new method allows the glass to "float", with the molten glass spreading out evenly over the surface of a liquid tin ...
The float glass production process can be divided into five universal steps: 1.Batching of raw materials: The main components, comprising silica sand, calcium oxide, soda & magnesium are weighed and mixed into batches to which recycled glass (cullet) is added. The use of 'cullet' reduces the consumption of energy.
Existing flat glass production methods created glass with irregular surfaces; extensive grinding and polishing was needed for many applications. The float glass process involves floating a glass ribbon on a bath of molten tin and creates a smooth surface naturally.
Float glass is manufactured using a melt process, where recycled glass, silica sand, lime, potash and soda are melted in a furnace and floated onto a bed of molten tin. The molten mass solidifies slowly while flowing over the bed of molten tin, after which it is annealed to remove stresses induced during the cooling process.
A float facility has a limited ability to produce less than its design capacity and as glass production is reduced the profit per ton drops precipitously. Even when only considering operating expense (OPEX) this means it is better is better operate a 600 tons per day (TPD) plant at 600 TPD rather than operate an 800 TPD plant at 600 TPD.

A float line can cost £100m to build, so once it starts, it runs 24 hours a day until it is shut down for repairs after about a decade. Float production is the main production mode of flat glass today, and its process can be divided into the following five stages: (1) Mixing of raw materials
Float Glass for Thin Glass. Efficient process control and outstanding quality: ISRA systems measure and inspect the optical quality, distortions, thickness, tension, and flatness of thin glass at the earliest possible point throughout the production process. This gives you full process and quality control, while also allowing you to reduce both ...
Float glass is a sheet of glass made by floating molten glass on a bed of molten metal, typically tin, although lead and other various low-melting-point alloys were used in the past. This method gives the sheet uniform thickness and very flat surfaces. Modern windows are made from float glass. Most float glass is soda-lime glass, although relatively minor quantities of specialty …
The float process for making flat glass was invented by Alistair Pilkington. This process allows the manufacture of clear, tinted and coated glass for buildings, and clear and tinted glass for vehicles. Pilkington had been experimenting with improving the melting process, and in 1952 he had the idea of using a bed of molten metal to form the ...

This is a ready-to-use business intelligence tool for existing manufacturers, new entrants as well as other participants in the value chain such as raw material suppliers, importers, exporters and distributors.
Where Auto Glass Manufacturing Starts. Automotive glass begins in the float glass manufacturing plant. This is where the raw ingredients, such as silica sand and limestone, are combined and float on a bed of molten tin to create a long ribbon of glass. The glass is called float glass in its raw form.
The art of manufacturing glass is an old one. It was a process which has been refined for thousands of years. With technology becoming increasingly advanced, glass manufacturers have begun producing float glass that is much sturdier, durable and compatible with glass processing procedures of lamination, tempering, acid etching, sand blasting, etc.
In the float glass process, a continuous strip of molten glass, heated to more than 1000 degrees Centigrade is poured from a furnace on to a large shallow bath of molten metal, usually tin. The glass floats and cools on the tin and spreads out to form a flat surface.
While each glass plant is different from the other, the float glass production process can be divided into five universal steps: Batching of raw materials: The main components, namely, soda lime glass, silica sand (73%), calcium oxide …
The Float Process for the forming of flat glass consists of floating a ribbon or sheet upon the surface of a bath of molten metal, usually tin. The Float Process is as well known in the art as the Pittsburgh Process and an extended description here is unnecessary. The Float Process is fully described in U.S. Pat. No. 3,083,551 to Pilkington.
The float glass process begins with a mixture of raw materials including key ingredients of silica sand, soda ash, limestone and dolomite. Melting A blend comprising of around 80% of this mixture and approximately 20% glass cullet (internally-reused scrap glass) is fed into a furnace and melted at extremely high temperatures.
Pilkington process (named for its inventor, Alastair Pilkington). This process, also known as the float-glass process, introduced a new technique for producing low-cost, high-quality sheets of flat glass. In float-glass manufacturing, molten glass is floated out on top of molten tin, creating a uniform sheet with a smooth, flat surface [4].
Le processus de fabrication du verre flotté est comparable à la préparation et la cuisson d'un repas soigneusement planifié. Vous commencez par recueillir tous les ingrédients requis, puis suivez un ensemble spécifique de processus qui incluent le chauffage à la bonne température, puis le refroidissement de la bonne manière.
Functions of a Float Bath • Need to produce glass as flat as possible –Bottom surface becomes flat since liquid tin (very dense) provides flat surface –Top surface becomes flat by glass flow due to gravity • Need to produce glass to needed thickness and width –ADS machines are used • Need to cool glass from 1100 C to 600 C
The control of the float glass production process comprises a multi-criteria decision making problem. The method of penalty functions was used to solve it [ 3 ]. The limits of the range of variation of the regime variables, taken to be the range for manual control of the technological process, were maintained in the simulation modeling.
Float glass can be made in thickness between 1.5 to 20mm. There are two techniques to accomplish this. To produce thin float glass, rollers control the width and speed of the glass ribbon. For thick float glass, the glass floats against graphite barriers, so that the ribbon flows out thicker. Thus the desired widths and thicknesses can be achieved.
While each glass plant is different from the other, the float glass production process can be divided into five universal steps: Batching of raw materials: The main components, namely, soda lime glass, silica sand (73%), calcium oxide (9%), soda (13%) and magnesium (4%), are weighed and mixed into batches to which recycled glass (cullet) is added.
Float glass manufacturing is not unlike the manufacturing of commodities like steel or plastic. Each of the processes requires raw materials to be weighed, mixed, melted at high temperatures, formed into continuous ribbons, cooled and cut into a size that fits its use.
The float process technology is the basis of all modern glass production, it also widely used for the production of glass bottles. The technology of producing of bottle glass consists of two production cycles: the cycle of glass mass technology and the technology cycle, which produces the final glass products.
