Assemblies and inserts are provided for evenly heating a smokable substance. A hookah bowl insert is provided for heating a smokable substance. The insert has a central core having at least one passageway extending therethrough. The insert further has a plurality of radial extensions extending in a radial direction from the central core. The radial extensions may be for gripping the smokable substance therebetween, and each radial extension has a vertical extension extending in a direction perpendicular to the radial direction. The insert is formed from a heat conductive material, such that heat is distributed across the insert, and within the individual radial and vertical extensions. Each vertical extension has a thickness larger than a thickness of the insert at the central core. As such, the vertical extensions can maintain stable temperatures and transfer heat to and from the smokable substance located therebetween.

A system for smoking a product includes a vase for containing a liquid. The vase has a closed bottom, and a side wall extending from the closed bottom and an open top that is unobstructed. The system further includes a bottle for inserting into and removing from the vase. The bottle has an open bottom, an open top, a flange circumscribing the bottle adjacent the open top, and a conical opening in the open top that is unobstructed. In addition, the system includes a grommet mounted to the open bottom of the bottle such that the open bottom is substantially unobstructed. Lastly, the system includes a bowl with a conical exterior that is complementary in shape to the conical opening in the bottle. The bowl can form a conical, glass-to-glass seal with the bottle.

A tobacco bowl includes a first member having a tobacco receptacle for receiving tobacco, a second member over the first member, and a coal plate for supporting a coal. The coal plate is on the second member, and the second member is moveable relative to the first member for adjusting a vertical distance between the coal place and the tobacco receptacle. The tobacco bowl may be part of a hookah. A method of using a hookah includes adjusting the distance between the coals and the tobacco.
