Introduction to Ultra Clear Glass
Ultra clear glass, also known as low - iron glass, is a type of high - quality glass with extremely low iron content. Compared with ordinary glass, it has significantly higher light transmittance, which can reach over 91.5% in some cases. This high light transmittance gives it excellent optical properties, making objects seen through ultra clear glass appear more vivid and real. Ultra clear glass is also highly resistant to weathering and corrosion, ensuring its long - term stability and durability. It is widely used in various fields, such as high - end architecture (for facades, skylights, and interior partitions), solar energy (solar panels), high - end furniture, and display cases.
