A transparent mirror is actually glass coated with a thin layer of metal so that part of the light falling on the surface of the mirror is reflected, and part passes through. In this case, light passes through in both directions.
If you use such glass to separate a well-lit room from a dimly lit one, then from the side of the bright room it will seem like a mirror, and from the other side it will look like a darkened window. This is explained by the fact that from the side of the illuminated room, the reflection will mask the light passing through the glass from a dark room. And from the side of a dark room, the picture will be the opposite: the light passing through the glass will be more intense than the reflected light.
One of the main coating materials used in manufacturing is titanium. Since titanium is a very resistant metal to external influences, such fabrics have virtually no restrictions on their use in various conditions. Depending on the metal impurities and their oxides used, various colors of mirror glass are obtained (blue, turquoise, gold and blue, green, steel, etc.) with varying degrees of reflection.
Mirror glass on the building makes the temperature inside the building comfortable during hot weather, which saves energy when air conditioners and fans are running and hides what is happening inside the building.
Such glass is often used by architects in the design of modern buildings. They are also actively used to equip meeting rooms, security service rooms and psychologists’ rooms.
