1. Body: A formation capable of holding within itself a liquid or a solid substance.
2. Rim: (A) A part of the vessel forming the termination of the body. (B) A part of the vessel recognizable by a change in the thickness of the material in the terminal sections.
3. Neck. A part of the vessel recognizable by a more or less sudden decrease in the rate of increase or decrease of the diameter.
4. Foot. An attachment to the vessel which serves as support to the body when upright.
5. Handle: A part of the vessel consisting of some outside attachment, not serving as support.
Body: It is suggested that in comparing the forms or cross-sections of vessels particular attention be paid to the proportion of the diameter to the height, to the rate of change of this proportion, to the place of change of direction in this proportion, and to refer to the following definitions of the two dimensions:
Height: the distance from the base to a horizontal plane passing through the most distant part of the rim.
Diameter: the distance from any one point on the sides to any opposite point on the sides, measured on a plane at right angles to the height.
Base: the point of contact or a plane of contact of the body with a horizontal surface.
Types. Body: These are so varied, depending on relative height and diameter of the cross-section, that an analysis is too cumbersome to be of service to general reference.
