World’s First 3D Engraving Technology in Glass Bottoms: cupustone®
Fuji Rock Glass cupustone® "Crane and Airplane"
Introducing a revolutionary technology that enables the display of engraved images visible from the glass's side.
cupustone®, a patented technology developed through years of research, employs a laser to carve images within the glass bottom. The engraving principle involves directing laser light to generate numerous micro-cracks, which then scatter light to form images inside the glass. Unlike conventional laser engraving, our technology allows image visibility from the side by adjusting laser output and point density. This is a global first in engraving technology.
3D internal engravings are clearly visible against a black background.
Continued Innovation
Our unique technology, cupustone®, invented in 2015, overcame previous limitations to achieve 3D photo engraving in glass bottoms. In 2018, we launched cupustone VI (Vertical In) for 3D engraving on vertical and curved surfaces. In 2019, we developed cupustone VIP (Vertical In Photography) for high-quality photo engraving visible from the glass's side. In 2022, we introduced cupustone VIP BB (Black Behind Vertical In Photography), where the glass shape acts as a convex lens to display a 180-degree black background, enhancing the engraved image.
