Starting from the bottom, the base of the jar is a flat and square shape with a raised platform which acts like a pedestal for the bigger and broader portion of the jar. The upper portion of the platform is portrayed and almost acts like legs, but the actual support comes from the sheeted plate at the bottom, which is completely flat for stability.
The next part of the jar is the body, and this portion is the largest and probably the focus of the entire piece and is where, if anything, would be stored. The shape of the container is similar to a three dimensional ellipse, and in this specific case looks like an egg turned upside down. However, unlike an egg, the piece harmonizes with the bottom portion and partitions itself into four planar sides, making an illusion of a linear yet rounded object.
On top of the body is what westerners would categorize as the "neck" and "cap" of the jar. The neck returns to the simple square motif of the raised base, but instead of being the platform for the body, it is the holder for the cap. The cap slightly changes the standards in comparison to the other parts, forming a removable pyramid lid that covers the neck's opening. From a first impression, the two together remind me of a simplified western home, where the foundation is rectangular cube crowned by triangular roof that converges at a high point in the middle. At the very top of the cap is what seems to be an extended arrow pointed straight up, the same shape and form as the lid for which it sits upon.
