  • Publication number: 20110005533
    Abstract: A mold for a smoking device comprises an insertable member removably connected to a body portion. The body portion generally comprises an elongated, preferably cylindrical tube having an open end and a closed end wherein a central axis extends along the axial length of the tube. The insertable member comprises an elongated member having a first end opposite a second end disposed along an axis and a cap portion extending radially outward around the first end. The body portion is filled with a liquid molding medium, such as water, and the insertable member is securely fastened to the body portion. The mold is exposed to a temperature change such that the molding medium changes phase from a liquid state to a solid state. The molded smoking product is removed from the mold and can be used for the user's benefit.
