Sapphire is a gemstone grade aluminate mineral, with a chemical composition of alumina. Its blue color comes from trace amounts of iron, titanium, chromium, and other elements. Sapphire glass refers to the synthesis of sapphire, which is made by using fine alumina powder to form sapphire crystal blocks in a high-temperature furnace and undergoing countless processes.

Besides its use in the jewelry industry, sapphire has many other applications. Sapphire is widely used in the field of optics due to its high transparency and optical properties. It is used as a window for lasers, a lens for optical instruments, and a cover for camera and mobile phone lenses. Sapphire has excellent heat resistance and chemical stability, allowing it to maintain its properties even in high temperatures and corrosive environments.

Sapphire is very hard, with a Mohs hardness second only to diamond. Since sapphire glass is so hard, can it be polished on frosted or regular glass? can't. Because frosted or ordinary glass may contain diamonds or diamond powder and debris, if in contact with them, it can scratch sapphire crystals; Due to its high hardness and brittle material, edge cracking and fragmentation are prone to occur during the processing. Usually, specialized carving machines are used for processing, which can effectively reduce costs and achieve high-precision machining.

Sapphire glass is a multifunctional special glass that plays an important role in many other fields such as optics, electronics, and industry, in addition to being used as jewelry, due to its excellent insulation properties and high thermal conductivity. Due to its corrosion resistance and high temperature performance, sapphire can be used for a long time in harsh working environments, ensuring the stability and reliability of the system. With the continuous development of technology, we believe that sapphire will continue to play an important role in various fields and bring more opportunities for innovation and application.
