Classification: 219/415

(under subclass 385) Subject matter including a casing structure, usually cylindrical, extending vertically below a supporting plane or surface structure and having a vertical dimension greater than its horizontal dimension, and having an open end contiguous with an opening in the supporting surface whereby a vessel or container, adapted to contain material to be heated, may be inserted into the interior thereof and subjected to the influence of heat energy generated by an associated heating unit or units. The heating unit generally is attached to the outer casing in a position to surround the inner container or to contact or transfer heat energy to the bottom of the container in the manner of a hot plate.
