Abstract: An electrical open-mouthed oven is provided to heat hollow hair rollers which contain a heat storage material. This material undergoes a change of state as the rollers are heated in the oven. It regains its original state upon cooling with the user''s hair wrapped around the rollers. At least a portion of each roller placed in the oven is adjacent a longitudinal strip heat sink which forms one internal wall of the oven. A graphite coated heating element is secured to the opposite surface of the heat sink and is covered with appropriate insulation. Layers of foam polyester insulation serve as internal oven walls on the opposite side, end and bottom of the oven. The foam insulation is enclosed within a shell which serves as a carrying case for the oven.
