Pre-oxidized：A suitable oxide layer is pre-oxidized on the metal
                     surface as a transition zone. The transition zone thus
                     enables the properties of the glass to gradually change
                     to those of the metal.
                     (Most metals require pre-oxidation)

Annealing：Reduce or eliminate the permanent stress generated during
                  the forming or thermal processing of glass, and enhance
                  the strain resistance of glass(lens).

Remove oxide：For optimal surface treatment of metal (electroplating
                        or electrochemical polishing), the metal oxide layer
                        must first be removed.
