Ceramic – Glass
Forming in the Bath - The float bath generally contains greater than hundred ton of molten tin. This is generally electrically heated and then purged into a nitrogen-hydrogen mixture. Then the glass is poured on to this molten tin where the glass floats because of the difference between the glass and the tin. The continuous ribbon of glass will then move through the tin bath and this movement will be controlled by heat. During this movement there will be top roll machines working on the glass top to form a desired thickness and width. The rollers are also the means of conveying system that drives the glass through the tin bath. The Glass enters the bath at a temperature of 1200C and leaves at a temperature of 575C – 625C. Glasses of thickness ranging from 0.3 mm to 25 mm can be produced in this method. This is the most preferred method, as we can obtain very good quality and quantity of production from this process.
