How is the engraving created in the glass?
Whatever material the lamp is made of, it is also high-quality aluminum. The glass is crystal clear optical glass. The glass is free of iron and therefore does not have a green color. Furthermore, there are no streaks or air bubbles in the glass, which is why the 3D laser engraving appears brilliant and very high quality. Furthermore, our glass is free of any tension in the glass. This is very important for the laser process. Internal stresses would cause cracks to form in the glass, either immediately or up to a few weeks later, or even cause the glass to shatter.
