The disclosure relates to a personal electronic vaporizer configured to receive a selected oven assembly and heat the medium therein in accordance with a heating profile associate with the selected oven assembly. The personal electronic vaporizer may define a pathway entirely surrounded by a material. The material is preferably an inert material such as glass or a material otherwise desirable to channel the vapors emitted by the heated medium to the user. The user may swap or select a different oven assembly associated with a different heating profile. The first oven assembly is thereafter removed from the personal electronic vaporizer and replaced with the newly selected oven assembly. The personal electronic vaporizer may automatically recognize the particular selected oven assembly and heat the substance therein according to a predefined heating profile associate with the oven assembly.
