How Are Mirrors Made?

Hundreds of years ago mirrors were reserved for the wealthy. Sheets of metals such as copper, silver, bronze and even gold were polished to a shine. Glass was also used but mirrors made from polished metal were preferred .

How are Mirrors Made Today?

There are primarily two components to commercially made mirrors: polished glass and a metallic coating, usually aluminum.

The process begins with cutting the polished glass. A saw is used in this part of the process. The saw contains diamond dust that is embedded in the blade and can cut through the glass easily.

The glass is then placed in a vacuum sealed chamber and coils of aluminum are placed behind the glass. All air is removed and the chamber is brought to an extremely high temperature. Once the ideal temperature is reached, fusion takes place between the glass and the aluminum, This process creates a reflective surface on the back of the glass. A protective paint is then applied over the aluminum to prevent oxidation.

Mirrors made for special purposes, such as telescopes, are manufactured using slightly different techniques, but the general principles are the same.

It is possible, and fairly easy, to make your own mirror using some basic materials. There are actually a few methods of making your own mirror, but there is one process that is very easy.

How Are Mirrors Made at Home?

In order to make your own mirror, only a few items are needed.

A piece of glass
Metallic silver spray paint
Paint sealer

Start out with a piece of clean glass.

Place the glass on a protected surface, either an old towel or newspaper.

Spray paint the back of the glass following directions on the spray can. Cover the back of the glass using sweeping motions. Repeat with additional coats as needed, let dry between coats.

To protect mirror from scratches, apply a coat of sealer over the dry silver paint.

Whether the mirror is purchased from a store or homemade, everyone can afford to have a mirror in their home.
