Architecture is the key feature of this vase designed by Bodil Kjær in the early 1960s, made by Cassina. It is made of transparent glass, which amplifies the complex shape of the object, similar to a skyscraper. Skyscraper is made of a transparent glass material mechanically pressed into a cast-iron mold to create the shape of a building. Furthermore, it must be processed at extremely high temperatures to make it as fluid as possible so that it can adhere to the shape of the mold. To recreate the architectural details found on Skyscraper, the glass must be heated up to a very high degree.
