In a preferred embodiment, the glass surface is printed with a pattern in the step (1).
In a preferred embodiment, the glass surface is not printed with a pattern in the step (1).
In a preferred embodiment, the glass is selected from one of tempered glass, ultra-white glass, anti-reflection self-cleaning photovoltaic glass, coated glass and high-alumina-silica glass. More preferably, the glass is tempered glass.
