Vetroin customizes glass by modifying the structure of its crystals and afterwards the natural transmission of light, through laser engraving performed in the thickness of the material. The laser beam penetrates into the glass creating micro-cracks that, in a proper and calculated way, make three-dimensional drawings or high-resolution images. This technique, combined with LED illumination from the edge of the glass panes, favours the reflection and refraction of light up to make any shapes bright and shiny.
