Handy guide to float glass manufacturing process raw materials

by Laboni on 15/05/2018
Float Glass, also known as Flat Glass, is a polished transparent glass used in the construction industry, for commercial glazing, and in shop display units. Float glass allows a high degree of light transmission, is resistant to chemical corrosion, and can be manufactured in various colours and varying opacities. These factors, paired with its distortion-free quality makes it an ideal choice for making windows, display units, cabinets, etc.

Manufactured and mastered by Sir Alaistair Pilkington in Great Britain in the 1950s, float glass remains a popular choice of material as far as modern architecture, both domestic and commercial is concerned. Float glass lies at the heart of the universal glass industry and is predicted to reach a 72.5 billion dollar industry worldwide*. If you have deliberated starting a glass manufacturing business, now is a good time to start making your business plan.

But, before you take the plunge, here’s a trim list of glass manufacturing process raw materials for float glass:

Silica sand

Soda ash

Recycled glass a.k.a. ‘cullet’



Sodium sulphate

For beginners in the domain, it is crucial to note that while silica sand is the main component in terms of quantity, soda ash is the most expensive raw material used in the manufacturing process. Soda ash, required in small quantities, comprises approximately 16 percent of the entire batch weight. But, it costs about 60 percent of the entire batch cost. Therefore, before setting up your float glass manufacturing business, factor in the availability and cost of each raw material by its share in production.

‘Cullet’ or recycled glass minimises energy consumption of the process and represents approximately 15 percent of the batch of raw materials used. Additionally, the use of recycled glass minimises CO2 emission and helps enhance the sustainability of the product.

In cases of production of tinted glass, additional ingredients are added at the melting stage of float glass production.

The float process used in manufacturing flat glass produces glass sheets that bear perfect, and smooth surfaces, uniform in thickness. This eliminates the need of any further polishing or grinding and makes them production ready for use, freshly out of the manufacturing unit.
