Mirrors are commonly made of glass with a smooth, polished surface that forms images by the reflection of rays and light. Mirrors are useful and practical devices and are commonly used in daily life.

Production instructions:
1) The original method of making glass mirrors consists of depositing metal coating,
mostly silver, on the surface of clear or body-tinted glass
2) The silver gives the mirror its reflective property
3) A layer of copper, which is in turn protected by a painted backing, usually protects
this deposit
