How is a mirror made?

Answer 1

The typical mirror is a sheet of glass that is coated on its back with aluminum or silver that produces images by reflection.

The mirrors used in Greco-Roman antiquity and throughout the European Middle Ages were simply slightly convex disks of metal, either bronze, tin, or silver, that reflected light off their highly polished surfaces. A method of backing a plate of flat glass with a thin sheet of reflecting metal came into widespread production in Venice during the 16th century; an amalgam of tin and mercury was the metal used. The chemical process of coating a glass surface with metallic silver was discovered by Justus von Liebig in 1835, and this advance inaugurated the modern techniques of mirror making.

Present-day mirrors are made by sputtering a thin layer of molten aluminum or silver onto the back of a plate of glass in a vacuum. In mirrors used in telescopes and other optical instruments, the aluminum is evaporated onto the front surface of the glass rather than on the back, in order to eliminate faint reflections from the glass itself.

Answer 2

A piece of glass is lined on one side with a reflective metal. In the past, a mirror was actually made from pure metal, typically silver, highly polished, which made mirrors quite expensive. But nowadays a piece of glass is normally silvered with aluminum (Silvering is the name of a deposition process; it can use metals other than silver.), and then the back of the metal is painted black to seal it off from corrosion. The reflection the viewer is normally interested in comes from the back of the mirror, from the metal surface. Glare is produced by the front of the mirror, where light is reflected by the glass surface. Mirrors for precision applications (such as space telescopes) will typically have the reflective metallic layer on the front instead of the back, and more complicated sealing processes are used to prevent glare and corrosion.

Answer 3

Mirrored... kidding

Answer 4

It's glass with either a foil or a layer of metal bonded to or deposited on the back side of it.

Answer 5

Typically a thin metal surface is applied to a very smooth sheet of glass.

Answer 6

it is a piece of glass with a very very thin piece of silver. if not silver than metal i think.

Answer 7

it is made of alaminium and sand
