Abstract
A glass panel having a noble material appearance, including in order: a glass sheet having a luminous transmission LTD of at least 85% and having a thickness in a range of 0.1 mm to 6 mm, a decorative layer having a noble material pattern and where the decorative layer is continuous, an opaque top layer where the opaque top layer is discontinuous. The glass panel thereby has opaque zones defined by an optical density OD>1.5, and semi-transparent zones that correspond to one or several patterns and defined by a luminous transmission LTD of from 3 to 80%.
