In this collection named “Null Set”, Studio Buzao explores the use of compound glass. Compound makes the glass more flexible. Bonded with UV glue, geometrically composited as volume from surface and with well-regulated line segmentation. Visible color is one of the ways God allows humans to perceive cosmic resonance. The visible light 400 to 490 (nm) band is chosen as the preferred design color system. Humans have experienced the hunting era of clear blue skies and water. And blue has become an innate preference. It has also become an intriguing color of the stability, calmness and rationality of the times. The design as a whole presents a transparent body with a thickness. The overlay of visible materials and the sense of its volume, have strengthened the existence of glass in space. It both exists and does not exist. From being to not being, a space evanescence, a visual abyss.
