Curved glass, also known as bent glass, is a type of glass that has been shaped into a curved or non-flat form during the manufacturing process. Unlike standard flat glass, curved glass is designed to have a specific curvature or bend, which can be either concave or convex. This curvature can vary from subtle to highly pronounced, depending on the intended application.

The production of curved glass involves a complex and specialized process known as “glass bending” or “glass curving.” Here’s an overview of how curved glass is manufactured:

1. Cutting: The first step is to cut the flat glass sheets into the desired shape and size before any curving takes place.

2. Heating: The cut glass is then heated in a furnace or kiln at high temperatures. The exact temperature and time depend on the type and thickness of the glass being used.

3. Bending: Once the glass reaches the appropriate temperature, it becomes pliable and can be shaped into the desired curve using molds or other specialized tools. The glass is carefully bent into its curved form and then allowed to cool down and solidify while maintaining the curved shape.

4. Annealing: After bending, the curved glass undergoes a process called annealing, where it is slowly cooled at a controlled rate to relieve internal stresses and ensure its structural integrity.
