Sheet Glass Manufacturing Process

Modern flat glass for architectural applications is commonly manufactured by the float glass process or less frequently using the older sheet process or the rolled process.

Sheet glass manufacturing process.

The float process glass which has been made since the time of the mesopotamians and egyptians is little more than a mixture of sand soda ash and lime. This allowed glass of virtually any thickness to be made non stop but the rollers would leave both sides of the glass marked and these would then need to be ground and polished. 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. It is lifted up horizontally and in doing so it catches up a sheet of molten glass.

Developed in 1959 this highly technical manufacturing process involves using some of earth s most abundant raw materials to produce a durable glass product. 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. When heated to about 1500 degrees celsius c this becomes a molten mass that hardens when slowly cooled. Float glass is more commonly known as window glass.

This process consists in simply pulling the molten glass either by hand or by mechanical equipment. Float glass is sheet glass made by floating molten glass on a bed of molten tin. When heated to about 1500 degrees celsius c this becomes a molten mass that hardens when slowly cooled. This method gives the glass uniform thickness and a very flat surface.

The first continuous ribbon process involved squeezing molten glass through two hot rollers similar to an old mangle. The float glass process is used to make high quality flat glass for the construction and automotive industry. Because it is inexpensive and sometimes free it is often used in the glass fusing process. The first successful method for making clear flat glass involved spinning.

The main ingredients involved in making flat glass are. This sheet is then allowed to pass over a large rotating roller. An iron bar is dipped sideways in the molten mass of glass. When heated to about 1500 degrees celsius c this becomes a molten mass that hardens when slowly cooled.

Batch processing is one of the initial steps of the glass making process. Some batch systems include material processing such as raw material screening sieve drying or pre heating i e. Glass which has been made since the time of the mesopotamians and egyptians is little more than a mixture of sand soda ash and lime. The first successful method for making clear and flat glass involved spinning.

When heated to about 1500 degrees celsius c this becomes a molten mass that hardens when slowly cooled.
