COLD PAINT FOR GLASS:
The glass represents in the collective imagination the idea of transparency: an almost magical material that, despite its thickness and its shape, lets see perfectly the whole world behind, creating deformations or plays of light depending on its shape and position.
This magic can be changed by coloring the glass itself. Imagine being able to see through a transparent red, blue, yellow or green colored glass! In order to maintain its characteristic, however, colored glass must maintain its natural characteristics: be cold, smooth, hard and fragile at the same time. In the past it was only possible to color the glass in its liquid state, i.e. by adding inorganic dyes into the melting basin to obtain a colored material. Despite the wide range of colors available, however, this processing was long and expensive.
