Abstract: Embodiments of the present invention relate to an improved kettle using conduction and convection, yielding improved boiling efficiency and methods of making the same. In one embodiment, a tea kettle comprises a handle, a spout, and a voluminous container having at least one passageway positioned about an outer surface of an inner containment wall of the voluminous container, for allowing a heated fluid to pass therethrough and conductively heat the inner containment wall. In another embodiment, a tea kettle comprises a voluminous container comprising an inner containment wall having a surface comprising a plurality of curves, and an outer wall having a surface comprising a plurality of curves, wherein at least one passageway is defined between an outer surface of the inner containment wall and an inner surface of the outer wall, for allowing a heated fluid to pass therethrough and conductively heat the inner containment wall.
