Types And Usage
There are many types of glass mirrors, each representing a different manufacturing process and reflection type.
1. An Aluminium Glass Mirror is made of a float glass manufactured using vacuum coating, i.e. aluminium powder is evaporated (or “sputtered”) onto the exposed surface of the glass in a vacuum chamber and then coated with two or more layers of waterproof protective paint.
2. A Low Aluminium Glass Mirror is manufactured by coating silver and two layers of protective paint on the back surface of glass.
3. A Safety Glass Mirror is made by adhering a special protective film to the back surface of a silver glass mirror, which prevents injuries in case the mirror is broken. This kind of mirror is used for furniture, doors, glass walls, commercial shelves, or public areas.
4. A Silkscreen Printed Glass Mirror is produced using inorganic color ink that prints patterns through a special screen onto glass. Various colors, patterns, and glass shapes are available. Such a glass mirror is durable and more moisture resistant than ordinary printed glass and can serve for over 20 years. This type of glass is widely used for decorative purposes.
5. A Silver Glass Mirror is an ordinary mirror, coated on its back surface with silver, which produces images by reflection. This kind of glass mirror is produced by coating a silver, copper film and two or more layers of waterproof paint on the back surface of float glass, which perfectly resists acid and moisture. A silver glass mirror provides clear and actual images, is quite durable, and is widely used for furniture, bathroom and other decorative purposes.
