FIELD: physics.
SUBSTANCE: mirror has a glass substrate, a silver coating layer and at least one paint layer applied on top of the silver coating. The colour of the paint layer is characterised by the following colour coordinates: L*, the value of which is less than 40; a*, the value of which ranges from -10 to +10; and b*, the value of which ranges from -10 to +10. The mirror does not have a copper layer.
EFFECT: no irregularities seen in the silver layer and reduced thickness of the silver coating.
