The configuration of the typical opium pipe consists of a long stem, a ceramic pipe-bowl, and a metal fitting, known as the "saddle", through which the pipe-bowl plugs into the pipe-stem. The pipe-bowl must be detachable from the stem due to the necessity to remove the bowl and scrape its insides clean of opium ash after several pipes have been smoked. The stems of opium pipes were usually made from
bamboo, but other materials such as
ivory and
silver were used. Pipe-bowls were typically a type of
ceramic, such as blue and white
porcelain. Sometimes opium pipe-bowls were carved from more valuable materials such as
jade. Because of its design, the opium pipe needed an opium lamp in order to function. The lamp was as highly specialized as the pipe, and was designed to channel the required amount of heat upon the pipe-bowl so that the opium would vaporise and allow the smoker to inhale the vapors. ==Rarity==
