ABSTRACT:
A smoking pipe which can be made of an artistically ornamented ceramic such as porcelain wherein means is provided for maintaining the outer wall at a sufficiently low temperature to permit comfortable handling by the smoker, there being spaced inner and outer bowls with provision for air circulation inwardly and upwardly between the bowls by convection, the convection flow not only serving as a cooling medium but also as an upward draft to assist in keeping the tobacco in a burning condition even while the smoker is not drawing air and smoke through the inner bowl and stem of the pipe. The inner bowl is removably held and sealed about its bottom by a novel sealing arrangement with a yielding heat resistant material such as silicone rubber which also supports part of the smoke passage means leading to the stem.
