The Imperial Yellow Corolla Vase is a decorative yellow vase that has its roots far in the past. The Imperial label is apropos for the porcelain vase because this piece is made of clay sourced from the area surrounding the kilns that produced objects for the Imperial estate during the heyday of the dynasties. The formulas to achieve the particular yellow on this vase's surface is a secret one guarded by ceramicist families devoted to the single color. The vibrant yellow hue was originally produced exclusively for those in high society.
