Very delicate vase.  Unique shape with a rich dark luster.  Close examination reveals an almost mottled mix of brown, yellow, green, and blue. The transition of the dark glaze to the white areas shows a slight blue tint at the lip. This, combined with the light silvery tint to the hard white porcelain would be characteristic of the reign. However, the age cracks visible on the base  are beneath the glaze, placing the piece at a later period.

Note:  Close examination of the vase reveals the intent of the artist was to give a greenish tint, but only to the neck by applying a light blue cobalt wash first.  This, mixing with the yellow in the brown, produced the effect. However it is not viewable unless examined under the right lighting conditions. Another very unique property of the vase is the effect left by being held in the right hand by the artisan before applying the glaze. A slight discoloration beneath the glaze clearly reveals a thumb print, and four finger prints. The surface of the glaze is unaffected in these areas, which says it was the oils in the hand which left the tell-tale trace.

What appears as a black vase is far from it. In the sunlight, it's shows like a polished gem full of color and life, which in fact it is.
