Specialty glass refers to a category of glass products designed for specific applications that require unique properties. This type of glass can include items like optical glass, borosilicate glass, and laminated glass, each tailored for functions such as high thermal resistance, enhanced clarity, or safety. These glasses are commonly used in various industries, including automotive, aerospace, and electronics. For example, tempered glass is often used in car windows for its strength, while fused silica is utilized in high-performance optics due to its low thermal expansion and high purity.
