Why is tin used in float glass process?

During the manufacturing process, the atmosphere inside the chamber is carefully controlled to ensure that float glass is manufactured correctly. The reason for using tin is that it is the only metal that remains stable in its liquid state at a high temperature of 600 degrees Celsius.

What is float bath in glass process?

The float glass process involves floating a glass ribbon on a bath of molten tin and creates a smooth surface naturally. Floating is possible because the density of a typical soda-lime-silica glass (~2.3 g/cm3) is much less than that of tin (~6.5 g/cm3) at the process temperature.

What is tin bath?

Noun. tin bath (plural tin baths) A bathtub made from galvanised iron. A bath filled with molten tin, used in the manufacture of glass. (less commonly) A bath made of tin.

How do you tell the tin side of a float glass?

The top surface of the glass is referred to as the air side or score side, and it is polished with fire. The bottom side is the tin side, and it is not fire polished.

How is tin used in glass?

Tin is used in the production of float glass in a liquid “tin bath” to provide a flat surface over which molten glass can float and solidify.

Is Toughened glass float glass?

Float Glass (also called Annealed Glass) is used as a base product to produce other types of glass such as Toughened Glass or Laminated Glass. It is manufactured by allowing the molten glass to cool slowly in a controlled environment.

What is the difference between float glass and toughened glass?

Tempered glass is harder to break, but poses more of a security risk when it is broken. In contrast, float glass is much easier to break, but the sharp shards of glass are going to cause big problems for any potential intruders.

Why there is a need for hydrogen and nitrogen in Bath while processing the glass?

Protective atmosphere for your tin bath Gases play an important role in the forming of float glass, where a nitrogen/hydrogen atmosphere is used to avoid oxidation of the glass tin and minimise the tin count in the glass.

How do you use a tin side detector?

When the Tin Side Detector lamp is placed on the tin side surface, the tin will turn fluorescence and produce a milky white image that is visible to the human eye. If you place the lamp on the non-tin side of the glass, the lack of tin results in no fluorescence and therefore only the duller image of the lamp is seen.

What is float process?

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.

Why choose our float glass tin bath?

Typically producing soda lime glass ribbons, our float glass tin bath can be adapted to suit a range of thicknesses up to 25 mm and a maximum pull up to 1,200 tpd. Designed for maximum reliability and the highest glass quality. Automotive laminated glass is particularly demanding in terms of optical quality.

How is float glass made?

The float glass process involves floating a glass ribbon on a bath of molten tin and creates a smooth surface naturally. Floating is possible because the density of a typical soda-lime-silica glass (~2.3 g/cm 3) is much less than that of tin (~6.5 g/cm 3) at the process temperature.

What is the float process?

The float process is based on a revolutionary idea by Sir Alistair Pilkington where molten glass is poured onto a bed of molten tin. This method is the basis of industrial flat glass manufacturing up until today. The molten glass is fed into the tin bath, which contains molten tin in an inert gas atmosphere.
