An improved melting retort and method of melting materials wherein the retort allows for easier material feeding capability with a wider range of types of materials while minimizing the movement of any unmelted materials to the pouring lip of the retort. The retort is mounted for rotation on either a bearing or rollers to enable feed materials directed into the retort from one peripheral location to be advanced into one or more several melt areas by rotating the retort about its central axis. In each of the melting areas, a heat source, such as an electron beam gun or plasma torch, is provided above the open top of the retort and melts the materials therebelow. In one embodiment, the molten material is poured from an inner peripheral portion thereof and gravitates through a central hole of the retort and into a secondary crucible or mold. In this geometry, the melted material can be fed into the secondary crucible in a continuous manner. In another embodiment, the pouring lip of the retort is at an outer peripheral portion for gravitation of the molten materials into a secondary crucible near the outer periphery of the retort. In either embodiment, the secondary crucible is provided with a heat source thereabove to shape the molten materials in the crucible.
