How do they make mirrors,glass,?

Answer 1

glass is melted sand or silica a mirror is a metal film usually silver

Answer 2

Early mirrors were usually a sheet of polished metal, often silver or copper, for example the Aranmula kannadi.

Most modern mirrors consist of a thin layer of aluminium deposited on a sheet of glass. They are back silvered, where the reflecting surface is viewed through the glass sheet; this makes the mirror durable, but lowers the image quality of the mirror due to extraneous reflections from the front surface of the glass. This type of mirror reflects about 80% of the incident light. The "back side" of the mirror is often painted black to completely seal the metal from corrosion.

Mirrors for precision optical applications are more likely to have the reflective coating on the front surface of the mirror, to improve the image quality. Metal films on the front surface are generally covered with a thin, transparent coating (often silica) to protect them from corrosion. In some cases, this coating may be designed to enhance the reflectivity as well.

Mirrors designed for special applications, such as in lasers and other advanced optical devices, use a reflective optical coating composed of many layers of different dielectric materials. Such coatings can be designed to have extremely high reflectivity and are reasonably durable. Since they absorb very little of the incident light, they can be used with high power lasers without being damaged by the intense beam

Answer 4

email me with this topic in the subject line and i will send u a video on the process

Answer 5

I am not that sure but I think its made from silica sand that heated to a melting temperature. I know that glass is technically in a liquid form. That is why in old windows you will find that the window pain is thicker at the bottom than the top.It's because over the years it has slowly run down from the top.
