    Abstract: A method and apparatus for heating a metallic material held by a holder such as a crucible which is positioned on a base using an electric furnace. The electric furnace includes a sleeve, an electric heating element disposed on the inner surface of the sleeve, a removable lid for covering a top opening of the sleeve and at least one handle disposed on the outer surface of the sleeve for lifting and removing the sleeve from the base or placing the sleeve on the base. When the sleeve is placed on the base enclosing the crucible, the removable lid is placed on the top opening of the sleeve and an electric current is applied to the electric heating element. Heat generated by the electric heating element and retained in the furnace melts the material contained in the crucible.
