Abstract

Darkening of the silver layer in classical glass mirror manufacturing process can be caused by the copper layer corrosion, this may take place by the environment action or residual chemicals remaining on the "mirroring" step. The present work describes a possible mechanism of copper coating corrosion, studying the corrosion product compositions formed inside the "spot". It was found that defect on the silver layer are associated with chemicals and moisture, they produce the copper layer corrosion and the development of blisters in the silver coating.
