Flat glass is used for windows, tables, and doors. It is made from sand, heated in a kiln, stretched, and cut. Defective glass is recycled. Custom cuts can be made at the main or secondary plant.
Flat glass is a type of glass usually produced for windows and other types of applications where flat glass may be required, such as for glass tables and doors. It is also called glass plate and glass plate. Glass is one of the most common types of glass in use today.
Flat glass is produced in many factories around the world in much the same way. The main ingredient in flat glass is sand, as many may know. However, turning that sand into flat glass is a complicated process that requires time, skill and special equipment.
When flat glass is ready to be made, the sand is mixed with other materials and placed in a large kiln capable of producing very high temperatures. This dissolves sand and other materials within minutes, turning them into a liquid. This liquid then forms the basis of what will become a solid plate of glass.
Once out of the kiln, the liquid glass is then made to the desired thickness by other machines that stretch the glass. It moves by placing it on liquid tin. Once cooled, the glass hardens but remains on the liquid tin. Tin remains liquid because its hardening point is lower than that of glass.
However, at this point, there’s still a long glass plate that isn’t practical for most uses. Glass is cut by engraving it with a tool that does not cut all the way through, but weakens the glass along a certain line. As the glass continues down the conveyor, it reaches a high point which puts pressure on the score line and breaks the flat glass into individual pieces.
Once cut, the glass is ready for inspection, which is done to determine if there are any defects on the edge or surface of the glass. If there is, the glass is recycled and reused, following much the same process it originally had. If no defects are found, it then goes to a staging area where it will be packed and shipped, usually through a fully automated process.
In some cases, flat glass will need to be cut manually to meet customer specifications. This can be done at the main plant or a secondary plant after delivery from the main manufacturer. Once the right size is obtained, it can then be placed into a frame, such as a window or door frame, or perhaps even a frame for a table, a television or many other types of uses.
