1. A method for manufacturing a cookware, the method comprising:
forming a fluid conduit defining a volume in a base of the cookware, the base comprising a heating zone configured for thermal communication with the fluid conduit, wherein forming the fluid conduit in the base of the cookware comprises forming a channel in the base of the cookware, the channel defining a cavity having a first diameter and sidewalls defining an opening having a second diameter that is less than the first diameter,
pressing a tube into the channel of the base of the cookware, wherein the fluid conduit is disposed within the tube, and
deforming the tube to a shape substantially similar to a shape of the channel,
introducing a working fluid to the fluid conduit via an open end of the tube, wherein a liquid phase of the working fluid occupies less than the volume of the fluid conduit, wherein the fluid conduit is sized and configured to form vapor segments and liquid segments interspersed throughout the fluid conduit from the working fluid;
sealing the open end of the fluid conduit to define a closed fluid system, wherein sealing the open end of the tube creates a first sealed end of the tube; and
fixing a cover, a handle, or a combination thereof over the first sealed end of the tube and a second sealed end of the tube.
 
10. A method for manufacturing a cookware, the method comprising:
forming a first fluid conduit defining a first volume in a first base section of a base of the cookware, the base comprising a heating zone configured for thermal communication with the first fluid conduit;
introducing a first working fluid to the first fluid conduit via an open end of the first fluid conduit, wherein a liquid phase of the first working fluid occupies less than a volume of the first fluid conduit, wherein the first fluid conduit is sized and configured to form vapor segments and liquid segments interspersed throughout the first fluid conduit from the first working fluid;
sealing the open end of the first fluid conduit to define a first closed fluid system;
forming a second fluid conduit in a second base section of the base of the cookware, the second fluid conduit defining a second volume;
introducing a second working fluid to the second fluid conduit via an open end of the second fluid conduit, wherein a liquid phase of the second working fluid occupies less than a volume of the second fluid conduit, wherein the second fluid conduit is sized and configured to form vapor segments and liquid segments interspersed throughout the second fluid conduit from the second working fluid; and
sealing the open end of the second fluid conduit to define a second closed fluid system.
