Patterned glass is to manufactured by two rollers, when the glass is at soft status, it goes through two rollers, the bottom roller surface is smooth, the upper roller have pattern at surface, when the roller rolls, the pattern can make the glass surface have the same pattern.

To manufacture clear patterned glass, we do not need add any special metal materials, just let the glass liquid in melting furnace to be clear, then we can get clear patterned glass. To manufacture tinted patterned glass, we need add some special metal materials to let the glass liquid in melting furnace to have different color as our demand, then we can get patterned glass with different colors, such as gray, bronze, blue, green, amber.

We can change the rollers with different patterns, then we can get different patterned glass.
