Pipe Anatomy

Pipe anatomy covers the parts of a pipe and the names given to them. Though seemingly a simple object, a pipe is made up of two main parts: the body (stummel), which contains the tobacco chamber and shank, and the mouthpiece (stem), taken into the mouth. Knowing these terms makes it easier to understand shape names and to follow discussions of care and smoking technique.

The Body: Bowl, Chamber and Shank

The body's most visible part is the bowl: the outer shell that surrounds the tobacco chamber, held in the hand while the pipe is filled and smoked. On most of today's pipes, the bowl is carved from briar. The cavity inside the bowl is called the chamber; tobacco is packed and lit here, and the chamber's diameter and depth directly affect the smoking character. The top surface of the bowl is called the rim, and its lowest point the heel. The heel matters both for cleaning and for the even development over time of the protective layer of carbon (cake) that builds up through smoking.

The section connecting the bowl to the mouthpiece is the shank. Running through the inside of the shank, from the base of the chamber to the end of the mouthpiece, is the smoke channel (draft hole). How straight and centered this channel is drilled is considered one of the primary measures of a pipe's craftsmanship.

Mouthpiece and Connection System

The mouthpiece (stem) is the part connecting the shank to the bite section; today it's most often made of ebonite (vulcanite) or acrylic. For a comparison of materials, see the mouthpiece materials entry. The fitting system that connects the mouthpiece to the body is called the mortise-tenon: the socket in the shank is the mortise, and the cylindrical projection at the end of the mouthpiece is the tenon. This fit provides an airtight but removable connection. In some pipes a 9mm activated-carbon or balsa filter is placed in the mortise, and in some models a metal piece called a "stinger," intended to reduce moisture and harshness, is fitted; details are in the pipe filters and systems entry.

The final section of the mouthpiece taken into the mouth (roughly its last 2.5 centimeters) is the bit. Some sources use "stem" and "bit" interchangeably; in this encyclopedia, mouthpiece refers to the whole part, and bit refers only to its tip. The raised projection at the tip is called the button; the pipe rests behind the teeth on this projection and is held without slipping. The flat opening where smoke exits toward the mouth is the slot, the final point of the smoke channel. In terms of form, mouthpieces fall into two main groups: tapered, which narrows to a point, and saddle, which is stepped.

Proportions and Multi-Piece Traditions

Just as important as the names of the parts is the ratio between them. On a classic Billiard pipe, for example, the shank length is expected to roughly equal the bowl height, and the mouthpiece to be 1.4-1.5 times the shank. Such ratios are taken as a mark of craftsmanship when defining classic pipe shapes. On the other hand, today's arrangement — body and mouthpiece joined by a single connection — is relatively recent: in examples like the German-Tyrolean tradition's fitted pipes (Gesteckpfeife) and the Ottoman çubuk, a pipe is a multi-piece object, and today's briar pipe is understood to have spread in the mid-19th century in the wake of these traditions.
