To produce the colored glass, glassmakers have used iron and cobalt oxides for the first time. When added to the molten glass, these so-called molecular dyes are completely soluble. Adding manganese, nickel and chrome oxides in adequate amounts gives a wide variety of colors.
In addition to molecular dyes, ion-plasma and magnetron sputtering techniques are also used for depositing alloys of the metals aluminum, silver, titan, nickel, and chrome onto glass products, as well as their compounds for producing coatings of different colors: blue, green, silver, golden, etc.
Aside from that, thanks to metal deposition glass has more enhanced properties and benefits. For example, the glass-manufacturing facility makes energy-efficient tinted glass.
