Mirror glass

Glass-forming process of surface reflection imaging chemical silvering and vacuum evaporation are two methods most commonly used method is the silver plating. This method is silver nitrate dissolved in water, add ammonia and sodium hydroxide solution and diluted ammonium hydroxide, silver double salt, made of silver liquid. To invert sugar or formaldehyde, potassium sodium tartrate solution was still liquid. Glass by cutting, grinding (if necessary by grinding and polishing), the surface cleaned with a dilute solution of stannous chloride sensitization, then wash, then liquid silver solution and also mixed immediately impregnated surface of the mirror formed after the wash, then to copper and coated with protective paint. Vacuum evaporation method is to wash the glass, placed in 0.1 ~ 10-4Pa degree of vacuum deposition device, the spiral tungsten power, generate heat to evaporate into a gaseous spiral in the alloy, deposited on the glass surface of the mirror . Electron gun can also be used instead of tungsten heating. Vacuum deposition may also be processed into a smooth metal surface mirror

Mirror: often placed in a particular corner of the home, such as bathrooms, are used to help make-up, shaving, combing hair and other grooming tools. Such a mirror is set into different sizes, small, portable, great to view all your clothes, it is also known as dressing mirror.

Instrument: Many optical instruments, such as telescope, microscope light path, will be carried out using a mirror reflection.

Security: for example transport and mirror rearview mirror. Some roads will be placing the convex corner, to remind between pedestrians.
