Are All Pipe Stems The Same Size?

 It usually refers to the whole shaft, but more commonly describes the final inch of pipe (which includes buttons and slots). This longer pipe is different than the above Canada in that it has a rounded stem. Like its sibling, the Liverpool, the Canadian has a long, oval-shaped stem, and short, slender mouthpiece. 

The stem is bent the opposite way to the stem, and positioned on top of the shank, it not only helps achieve a good balance while sitting on a pipe, it takes on an appearance very similar to gnarled tree branches, which adds to its fitting name. The shank on the typical Apple Pipe is usually of equal length with the height of the bowl, and usually has a tapered stem. With the more round Apple-like bowl, but with the same shape as the billiard, straighter stems are once again equal to the bowls height, and mouthpieces are usually tapered. 

Like the Bending Billiard, above, most bowl shapes may either have a curve to the mouthpiece, or have both the stem and the mouthpiece curved. Bulldog pipes come in both curved and bent varieties as well (not to be confused with Rhodesian shapes). The curves on the stem/mouthpieces make the pipes much more comfortable for hanging and smoking hands-free. 

Most pipes are never cut perfectly round and straight, and that is obvious when rotating the stem 180 degrees. Some pipe smokers dislike the feeling of the plastic stem when they smoke. You cannot clean a pipe with a plastic stem when you are smoking, and leaving the filter in the pipe for too long may cause negative effects. With the stem and shank apart (and preferably after giving a nice run with the pipe cleaner, might even be better to do this before loading your obstruction filter) just insert your filter in your shank. 

For use on stems, amber is typically hand-shaped; first dipped into oil, and then heated, at which point it loses most of its brittle qualities. The advantages of Acrylic pipe stems are color diversity, and unlike Vulcanite, Acrylic does not oxidize. Meanwhile, most antique pipes had stems made from vulcanite, which is a synthetic rubber that you can polish to shine. The two most common materials used for tobacco pipe stems are acrylic and vulcanite, otherwise known as Lucite and ebonite, respectively. 

Clay pipes often have longer stems, with Churchwarden models still being produced. Churchwarden While most pipes are identified by the bowl shape, Churchwardens are easily recognized by their exceptionally long stems. Not a design per se, these are any pipes fitted with an extra-long stem to allow them to be smoked without blocking the view. Perhaps the most ubiquitous of pipe shapes, a Billiard has a cylindrical bowl, a shank equal to the height of the bowl, and can wear any kind of stem, still remaining a Billiard.
