Gorilla Glass Properties and Manufacturing

The video explains the manufacturing process of Gorilla Glass, highlighting its durability, thin form factor, and superior surface quality. It details the chemical strengthening through ion exchange, which enhances damage resistance. The fusion process ensures a clean, smooth surface, making it ideal for touchscreens. The video also covers the ion exchange process, where potassium ions create a compressive stress layer, further increasing the glass's resistance to damage.
