Figure 11.15-2 is a flow diagram of a typical batch plant. The furnace most commonly used is a continuous regenerative furnace capable of producing between 45 and 272 megagrams (Mg) (50 and 300 tons) of glass per day. A furnace may have either side or end ports that connect brick checkers to the inside of the melter.

production. Float glass is a type of glass made by floating molten glass on a bed of molten metal. This method of glass production is also known as the Pilkington Process, named after its inventor, Sir Alastair Pilkington. The process involves melting silica sand, soda ash, and limestone in a furnace at a temperature of around 1600°C.

The float process. During float glass production, the raw materials are mixed together and melted in the furnace to form molten glass which is then poured into a bath of molten tin. The furnace uses air and natural gas combustion to melt the raw materials. As the glass cools and solidifies, it floats in the tin bath forming a glass ribbon.

Design furniture made of float glass: classic, noble. Float glass is also valued in furniture design: with its immaculately smooth surface and crystal-clear transparency, it is ideal for the production of fine glass furniture. The typical float glass shimmers slightly greenish and has a clear green to green-black color at the edges.

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.

These materials are mixed together in the proper proportions and melted together in a furnace at temperatures of over 2000°F.

This is the basic recipe for float glass, one of the greatest of all industrial process inventions, comparable with Bessemer's innovations in steel manufacturing. In fact, this is the formula for many types of mass-produced glass; except that float demands highly exacting standards of quality, care and control beyond those of other everyday ...

A float plant, which operates non-stop for between 11-15 years, makes around 6000 kilometers of glass a year in thicknesses of 0.4mm to 25mm and in widths up to 3 meters. The float process has been licensed to more than 40 manufacturers in 30 countries.

Float glass is made by pouring the molten glass from a furnace into a chamber that contains a bed of molten tin. The process is sometimes call the Pilkington Process.
