About Float Glass

Float glass is a high-quality, distortion-free glass produced by floating molten glass on molten tin. This innovative manufacturing process, known as the Pilkington process, ensures uniform thickness and a smooth surface on glass, making it ideal for windows and various architectural applications. The modern float glass process was developed by Sir Alastair Pilkington between 1953 and 1957, transforming glass production. Also, float glass transmits about 87% of light and is commonly used in buildings due to its aesthetic appeal and energy efficiency.

Properties of Float Glass

Float glass is described by high optical clarity and distortion-free transparency, allowing for clear, undistorted views. Additionally, float glass is durable and scratch-resistant, capable of withstanding high stress levels. Typical thickness ranges from 0.4 mm to 25 mm, depending on the application. While it has a slight greenish tint and transmits around 87% of incident light, its flexural strength varies, with untreated float glass at approximately 45 N/mm sq. and tempered glass reaching up to 200 N/mm sq. These properties make float glass ideal for use in windows, mirrors, furniture, electronics, and solar panels.

Manufacturing Process of Float Glass

The production process of float glass begins with the mixing of raw materials, which include silica sand, soda ash, limestone, dolomite, and cullet, in specific proportions. This mixture is then heated in a furnace at approximately 1550°C to create molten glass. The molten glass flows onto a bath of molten tin, where it spreads and flattens, forming a smooth glass ribbon. As the glass exits the tin bath at around 600°C, it enters an annealing lehr for gradual cooling and then undergoes quality inspections and is cut to size for storage and shipping.

Making of Float Glass

The production process involves several key steps, such as:

1. Raw Materials Preparation

The primary raw materials for float glass production are silica sand (SiO2), soda ash (Na2CO3), limestone (CaCO3), and dolomite (CaMg(CO3)2). These materials must be prepared and measured accurately to ensure the proper composition of the final glass.

2. Melting Process

The raw materials are mixed and fed into a furnace where they are heated to high temperatures (around 1500°C) to form molten glass. 

The main chemical reactions occurring in the furnace are:

• SiO2 + Na2CO3 → Na2SiO3 + CO2

• CaCO3 → CaO + CO2

• CaO + SiO2 → CaSiO3

3. Float Bath

The molten glass is then fed into a bath of molten tin. The glass floats on the tin and spreads out to form a flat, even surface. This process results in a glass sheet with uniform thickness. The molten tin does not react with the glass, which helps maintain the purity and clarity of the glass.

4. Annealing Process

After forming in the float bath, the glass moves through an annealing lehr, where it is slowly cooled to relieve internal stresses. This process is crucial to ensure the strength and durability of the final glass product.

5. Cutting and Inspection

Once the glass has cooled and solidified, it is cut to the desired sizes and inspected for any defects. The final product is then packaged and prepared for shipment.

Applications and Drivers of Float Glass

The float glass market is driven by increasing demand from the building and construction industry, where it is used for windows, doors, facades, and interior. The growing emphasis on sustainability and energy-efficient buildings is another major growth driver, as advanced glass varieties with improved thermal insulation properties help minimise heat transfer within buildings, leading to reduced energy consumption for heating and cooling. 

The rising popularity of solar energy is also a significant growth driver, as float glass provides a clear and durable surface for solar panels, allowing them to capture maximum sunlight and convert it into electricity. Additionally, the automotive industry is a key application area, with demand being driven by changing consumer preferences for high-quality glass in vehicle windshields and windows.
