People started using mirrors a long time ago. The first mirrors used were natural mirrors such as reflection in water. The first man-made mirrors were made out of the rock. Later, people used different metals such as bronze（青铜） to make mirrors. Throughout history, different types of mirrors have been used in many different cultures at the same time.
The first glass mirror was invented by a German named Justus Von Liebig in 1835.He used a silvering（镀银） technique to produce the glass mirror. Today aluminum is the main metal used for mirror.
Today, mirrors come in various shapes and sizes. They are used for different reasons. We usually start our days by looking into the mirror in the bathroom. We also use them often during the day to keep ourselves tidy.
Mirrors are important for cars too. If cars don't have mirrors, it's impossible to drive. This is because drivers can't see other cars coming. Of course, that would lead to many car accidents. It is said that breaking a mirror causes seven years of bad luck. So, look after your mirrors well.
