Ger van Oers

This is a Tiffany-style stained glass table lamp, belonging to the Art Nouveau movement (a classic reproduction of aesthetics). It is made of spliced ​​pieces of glass of different colors, with off-white, light blue, and warm yellow as the main colors. The bottom is decorated with gold twisted patterns, and a red glass piece is embellished in the center. When light passes through it, it forms soft colored spots, combining decoration and atmosphere.
