Smoking pipe (tobacco)
A smoking pipe is a pipe that is specifically made to smoke tobacco. Typically, it will consist of a chamber (the bowl) for the combustion of material and a thin stem (shank) ending in a mouthpiece (the bit). Pipes can range from the very simple machine-made briar pipe to highly-prized handmade and artful implements created by renowned pipemakers which are often very expensive collector's items. "Estate pipes" are previously owned pipes that are sold to new owners.
The bowls of tobacco pipes are commonly made of briar, meerschaum, corncob or clay. Less common are cherrywood, olivewood, maple, mesquite, oak, and bog-wood. Generally a dense-grained wood is ideal. Minerals such as catlinite and soapstone have also been used. Pipe bowls of all these materials are sometimes carved with a great deal of artistry.
Unusual, but still noteworthy pipe bowl materials include gourds, as in the famous Calabash pipe, and pyrolytic graphite. Metal and glass are uncommon materials for tobacco pipes, but are common for pipes intended for other substances, such as cannabis.
The stem needs a long channel of constant position and diameter running through it for a proper draw, although filter pipes have varying diameters and can be successfully smoked even without filters or adapters. Because it is molded rather than carved, clay may make up the entire pipe or just the bowl, but most other materials have stems made separately and detachable. Stems and bits of tobacco pipes are usually made of moldable materials like vulcanite, lucite, Bakelite, and soft plastic. Less common are stems made of reeds, bamboo, or hollowed out pieces of wood. Expensive pipes once had stems made of amber, though this is rare now.
Tobaccos for smoking in pipes are often carefully treated and blended to achieve flavour nuances not available in other tobacco products. Many of these are blends using staple ingredients of variously cured Burley and Virginia tobaccos which are enhanced by spice tobaccos, among them many Oriental or Balkan varietals, Latakia (a fire-cured spice tobacco of Syrian origin), Perique (uniquely grown in St. James Parish, Louisiana) which is also an old method of fermentation, or blends of Virginia and Burley tobaccos of African, Indian, or South American origins. Traditionally, many U.S. blends are made of American Burley with sweeteners and flavorings added to create an "aromatic" flavor, whereas "English" blends are based on natural Virginia tobaccos enhanced with Oriental and other natural tobaccos. There is a growing tendency towards "natural" tobaccos which derive their aromas from artful blending with selected spice tobaccos only and careful, often historically-based, curing processes.
The majority of pipes sold today, whether hand made or machine made, are fashioned from briar (French: bruyère). Briar is a particularly well suited wood for pipe making for a number of reasons. The first and most important characteristic is its natural resistance to fire. The second is its inherent ability to absorb moisture. The burl absorbs water in nature to supply the tree in the dry times and likewise will absorb the moisture that is a byproduct of combustion. Briar is cut from the root burl of the tree heath (Erica arborea), which is native to the rocky and sandy soils of the Mediterranean region. Briar burls are cut into two types of blocks; ebauchon and plateaux. Ebauchon is taken from the heart of the burl while plateaux is taken from the outer part of the burl. While both types of blocks can produce pipes of the highest quality, most artisan pipe makers prefer to use plateaux because of its superior graining.
From the 1960s onwards and with Denmark as the world pipemaking "centre", the making of briar pipes has developed into a fine art, with some outstanding individual makers revered in the pipe-smoking and pipe-collecting world. Some of the finest are the Swede Sixten Ivarsson (probably the most legendary pipemaker ever), the Danes Bo Nordh, Lars Ivarsson, Nanna Ivarsson, Jess Chonowitsch, Poul Ilsted, Teddy Knudsen, Peder Jeppesen (formerly Neerup) and the Italians Carlo Scotti, Achille Savinelli and Claudio Cavicchi.
Meerschaum (hydrated magnesium silicate), a mineral found in small shallow deposits mainly around the city of Eskişehir in central Turkey, is prized for the properties which allows it to be carved into finely detailed decorative and figural shapes. It has been used since the 17th century and, with clay pipes, represented the most common medium for pipes before the introduction of briar as the material of choice in the 19th century. The word "meerschaum" means "sea foam" in German, alluding to its natural white color and its surprisingly low weight. Meerschaum is a very porous mineral that absorbs elements of the tobacco during the smoking process, and gradually changes color to a golden brown. Old, well-smoked meerschaum pipes are valued by collectors for their distinctive coloring. In selecting a meerschaum pipe it is advisable to verify that the product is indeed carved from a block of meerschaum, and is not made from meerschaum dust collected after carving and mixed with a binder then pressed into a pipe shape. These products are not absorbent, do not color, and lack the smoking quality of the block carved pipe.
Clay in this case is almost always a very fine white clay. Low-quality "clay" pipes are actually made from porcelain slip poured into a mold. These are porous, of very low quality, and impart unwanted flavors to a smoke. Top-notch clays, on the other hand, are made in a labor-intensive process that requires beating all air out of the clay, hand-rolling each pipe before molding it, piercing with a fine wire, and careful firing. Traditionally, clay pipes are un-glazed. Clays burn "hot" in comparison to other types of pipes, so they are often difficult for most pipe-smokers to use. Their proponents claim that, unlike other materials, a well-made clay pipe gives a "pure" smoke, with no flavor addition from the pipe bowl. In addition to aficionados, reproductions of historical clay styles are used by some re-enactors. Clay pipes were once considered disposable items and the rapidly changing designs in the past are often used as an aid in dating by archaeologists. They were once very popular in Ireland, where such a pipe was called a dúidín.
Calabash gourds (usually with meerschaum or porcelain bowls set inside them) have long made prized pipes, but they are labour-intensive and, today, quite expensive. Because of this expense, pipes with bodies made of wood (usually mahogany) instead of gourd, but with the same classic shape, are sold as calabashes. Both wood and gourd pipes are functionally the same. They consist of a downward curve that ends with an upcurve where the bowl sits. Beneath the bowl is an air chamber which serves to cool, dry, and mellow the smoke. There are also briar pipes being sold as calabashes. These typically do not have an air chamber and are named only because of their external shape.
A calabash pipe is rather large and easy to recognize as a pipe when used on a stage in dramatic productions. Early portrayers of the character Sherlock Holmes, particularly William Gillette and Basil Rathbone, took advantage of this fact when it was required to portray Holmes smoking. This is why Holmes is stereotypically depicted as favouring a calabash. In fact, most stories, particularly The Adventure of the Copper Beeches, described him as preferring a long-stemmed cherry-wood or a clay pipe.
On the other end of the scale, "corncob" pipes made from corn cobs are cheap and effective, even if some regard them as inelegant. The cobs are first dried for two years. Then they are hollowed out to make a bowl shape. The bowls are dipped in a plaster-based mixture and varnished or lacquered on the outside. Shanks made from pine wood are then inserted into the bowls. The first and largest manufacturer of corncob pipes is Missouri Meerschaum, located in Washington, Missouri in the USA. Missouri Meerschaum has produced the pipes since 1869. General Douglas MacArthur, Mark Twain, and Norman Rockwell were perhaps the most famous smokers of this type of pipe, along with the cartoon characters Popeye and Frosty the Snowman.
Corncob pipes remain popular today because they are inexpensive and require no "break-in" period like briar pipes. For these two reasons, corncob pipes are often recommended as a "Beginners pipe." But, their enjoyment is by no means limited to beginners. Corncob pipes are equally valued by both learners and experienced smokers who simply desire a cool, clean smoke. Pipesmokers who wish to sample a wide variety of different tobaccos and blends also might keep a stock of corncobs on hand to permit them to try new flavors without "carryover" from an already-used pipe, or to keep a potentially bad-tasting tobacco from adding its flavor to a more expensive or favored pipe.
A variety of other materials may also be used for pipes. The Redmanol corporation manufactured pipes with translucent stems in the 1920s and a series of pipes was manufactured and distributed by the Tar Gard (later Venturi) Corporation of San Francisco from 1965-1975. Marketed under names such as "the pipe," "THE SMOKE" and "Venturi," they used materials such as pyrolytic graphite, phenolic resin, nylon, Bakelite and other synthetics, allowing for higher temperatures in the bowl, reduced tar and aesthetic variations of color and style. After Venturi stopped making pipes, several companies continue to make pipes from Brylon, a composite of nylon and wood flour, as a cheaper substitute for briar.
Metal is an uncommon material for making tobacco pipes, but they are not unknown. The most common form of this is a pipe with a shank made of aluminum, which serves as a heat sink. Mouthpieces are made of vulcanite or lucite. The bowls are removable, though not interchangeable between manufacturers. They are made of varying materials to allow the smoker to try different characteristics or to dedicate particular bowls for particular tobaccos.
A hookah, ghelyan, or narghile, is a Middle Eastern water pipe that cools the smoke by filtering it through a water chamber. Often ice, cough-drops, milk, or fruit juice is added to the water. Traditionally, the tobacco is mixed with a sweetener, such as honey or molasses. Fruit flavors have also become popular. Modern hookah smokers, especially in the US, smoke "me'assel" "moassel" "molasses" or "shisha" all names for the same wet mixture of tobacco, molasses/honey, glycerine, and often, flavoring. This style of tobacco is smoked in a bowl with foil or a screen (metal or glass) on top of the bowl. More traditional tobaccos are "tombiek" (a dry unflavored tobacco, which the user moistens in water, squeezes out the extra liquid, and places coals directly on top) or "jarak" (more of a paste of tobacco with fruit to flavor the smoke).
Smoking a pipe requires more apparatus and technique than cigarette or even cigar smoking. In addition to the pipe itself and matches or a lighter, smokers usually require a pipe tool for packing, adjusting, and emptying the tobacco in the bowl, and a regular supply of pipe cleaners.
Pipe tobacco 
Pipe tobacco can be purchased in several forms, which vary both in flavour (leading to many blends and opportunities for smokers to blend their own tobaccos) and in the physical shape and size to which the tobacco has been reduced. Most pipe tobaccos are less mild than cigarette tobacco, substantially more moist and cut much more coarsely. Too finely cut tobacco does not allow enough air to flow through the pipe, and overly dry tobacco burns too quickly with little flavour. Pipe tobacco must be kept in an airtight container, such as a canning jar or sealed tin, to keep from drying out.
Some pipe tobaccos are cut into long narrow ribbons. Some are pressed into flat cakes which are sliced. Others are tightly wound into long ropes, then sliced into discs. Flake tobacco (sliced cakes or ropes) may be prepared in several ways. Generally it is rubbed out with the fingers and palms until it is loose enough to pack. It can also be crumbled or simply folded and stuffed into a pipe. Some people also prefer to dice up very coarse tobaccos before using them, making them easier to pack.
In the most common method of packing, tobacco is added to the bowl of the pipe in several batches, each one pressed down until the mixture has a uniform density that optimizes airflow (something that it is difficult to gauge without practice). This can be done with a finger or thumb, but if the tobacco needs to be repacked later, while it is burning, the tamper on a pipe tool is sometimes used. If it needs to be loosened, the reamer, or any similar long pin can be used. A traditional way of packing the pipe is to fill the bowl and then pack gently to about 1/3 full, fill again and pack slightly more firmly to about 2/3 full, and then pack more firmly still to the top.
An alternate packing technique called the Frank method involves lightly dropping tobacco in the pipe, after which a large plug is gingerly pushed into the bowl all at once.
Matches, or separately lit slivers of wood are often considered preferable to lighters because of lower burning temperature. Butane lighters made specifically for pipes emit flame sideways or at an angle to make it easier to direct flame into the bowl. Torch-style lighters should never be used to light a pipe because their flames are too hot and can char the rim of the pipe bowl. Matches should be allowed to burn for several seconds to allow the sulfur from the tip to burn away and the match to produce a full flame. A naphtha fueled lighter should also be allowed to burn a few seconds to get rid of stray naphtha vapors that could give a foul taste to the smoke. When a flame has been produced, it is then moved in circles above the rim of the bowl while the smoker puffs to draw the flame down and light the tobacco. Packing method and humidity can affect how often a pipe must be relit.
Burning prevention 
With care, a briar pipe can last a very long time without burning out. However, due to aggressive (hot) smoking, imperfections in the wood, or just bad luck, a hole can be burned in the tobacco chamber of the pipe. There are several methods used to help prevent a wood pipe from burning out. These generally involve pre-coating the chamber with any of a variety of substances, or by gently smoking a new pipe to build up a cake (a mixture of ash, unburned tobacco, oils, sugars, and other residue) on the walls.
Many modern briar pipes are pre-treated by the manufacturer to resist burning. If smoked correctly, the cake will build up properly on its own. Another technique is to alternate a half-bowl and a full-bowl the first several times the pipe is used to build an even cake. Burley is often recommended to help a new pipe build cake.
The effectiveness of these methods is by no means universally agreed upon.
NOTE: The caked layer that helps prevent burning through the bottom or sides of a briar wood pipe may damage other pipes, such as meerschaum or clay. As the cake layer heats up, it expands and may cause cracks or breaks in non-briar pipes.

Pipe smoke, like cigar smoke, is usually not inhaled. It is merely brought into the mouth, pumped around oral and nasal cavities to permit absorption of nicotine toward the brain through the mucous membranes, and released. It is normal to have to relight a pipe periodically. If it is smoked too slowly, this will happen more often. If it is smoked too quickly, it can produce excess moisture causing a gurgling sound in the pipe and an uncomfortable sensation on the tongue (referred to as "pipe tongue", or more commonly, "tongue bite").
A pipe cleaner can be used to dry out the bowl and, wetted with alcohol, the inner channel. The bowl of the pipe can also become uncomfortably hot, depending on the material and the rate of smoking. For this reason clay pipes in particular are often held by the stem. Meerschaum pipes are held in a square of chamois leather, with gloves, or else by the stem in order to prevent uneven coloring of the material.
The ash and the last bits of unburned tobacco, known as dottle, should be cleaned out with a suitable pipe tool. A soft or bristle pipe cleaner, which may be moistened with strong spirits is then run through the airways of the stem and shank to remove any moisture, ash, and other residue before the pipe is allowed to dry. A pipe should be allowed to cool before removing the stem to avoid the possibility of warping it.
A cake of ash eventually develops inside the bowl. This is generally considered desirable for controlling overall heat. However, if it becomes too thick, it may expand faster than the bowl of the pipe itself when heated, cracking the bowl. Before reaching this point, it needs to be scraped down with a reamer. It is generally recommended to keep the cake at approximately the thickness of a U.S. dime (about 1/20th of an inch or 1.5 mm), though sometimes the cake is removed entirely as part of efforts to eliminate flavors or aromas.
Cake is considered undesirable in meerschaum pipes because it can easily crack the bowl and/or interfere with the mineral's natural porosity. Meerschaum also softens when heated so it is recommended to allow meerschaum pipes to cool before cleaning as people have been known to push pipe cleaners through the walls of heated pipes.
When tobacco is burned, oils from adjoining not yet ignited particles vaporize and condense into the existing cake on the walls of the bowl and shank. Over time, these oils can oxidize and turn rancid, causing the pipe to give a sour or bitter smoke. An effective measure called the Professor's Pipe-Sweetening Treatment involves filling the bowl with kosher salt and carefully wetting it with strong spirits. Many experts feel that it is important to not use iodized salt, as the iodine and other additives may impart an unpleasant flavor. Some people find that regularly wiping out the bowl with spirits is helpful in preventing souring. Commercial pipe-sweetening products are also available.

Pipes have been used since ancient times. Herodotus described Scythians inhaling the fumes of burning leaves in 500 B.C. Romans, and Greeks adopted pipes from their neighbors to the east and they were subsequently used by Germanic, Celtic and Nordic tribes.
As tobacco was not introduced to the Old World until the 16th century, the pipes outside of the Americas were usually used to smoke hashish, a rare and expensive substance outside areas of the Middle East, Central Asia and India, where it was produced.
Native Americans smoked tobacco in pipes long before the arrival of Europeans. The tobacco plant was native to South America but spread into North America before Europeans arrived. Tobacco was introduced to Europe from the Americas in the 16th century and spread around the world rapidly.
