Knowledge of Mirror Making:
In the production process of common silver mirror, after painting the reflective silver, it will painting a layer of Cu to protect the silver coating.(For Ag is a really active chemical element, when exposing to the air, it will be easily oxidized , like the silver jewelry will become dark and gray after a long time.) While the Cu is a heavy metallic element, in the producing and using process of the silver mirror, the Cu garbage will do a great influence to the environment. So for many years, the industry has always want to using some kind of environmental material to replace the Cu, but it didn’t succeed.
