Clear float glass is made by pouring the molten glass made by a specific proportion of quartz, soda ash and dolomite from a furnace into a chamber that contains a bed of molten tin. The combination of gravity and surface tension makes the smooth surface of the glass. Then by the roller table, the glass is moved to the annealing lehr, where it is cooled down and cut into clear glass sheets, featured with smooth, parallel surfaces and extremely low optical distortion.
- Suitable for efficient manufacturing of high-quality flat glass with uniform thickness, smooth surfaces, free from any ripple marks or irregularities.
- Low energy consumption on the production line with high product yield. The fully mechanized and automated production line ensures high efficiency.
- Continuous production for several years, resulting in stable supply of high-quality clear float glass.
- Providing environment for production of new varieties such as electric float reflective glass and spray-coated glass during annealing.
Did you know that the float glass process, which is now one of the main methods used worldwide for producing flat glass, was first developed by the British company Pilkington in 1952? Since then, other glass manufacturers followed suit and began developing their own versions, which ultimately led to the three main float glass processes used today: the Pilkington Process in the UK, the Pittsburgh Process in the US, and the Chinese Float Process.
