Have a look into the history of mirrorMirrors have been around for awhile, but they haven't always been made of glass. The first mirrors, from around 600 B.C., were very simple. They were polished surfaces from natural materials that could reflect an image. After awhile, people started making mirrors from copper, bronze, gold and silver. These metals are heavy, so the mirrors were very small. They couldn't really be used to see a reflection so they were mostly for show.
Glass mirrors like we have today were first made in the Middle Ages. They didn't have the modern technology used today, so the mirrors were difficult to make and expensive. In the Renaissance period after the Middle Ages, the technique of making mirrors developed. Mirrors could show a clearer image. Artists even used mirrors to paint self-portraits. They were still very expensive so only the rich could afford them. The process for making modern mirrors was developed in 1835.
