Heat treatment apparatus and method of using same

Apparatus for melting a solid mass of wax comprising:

• a housing having a base and a sidewall;
• a heating element disposed inside the housing and positioned near the base for generating heat;
• a heat conducting plate positioned above the heating element for conducting the heat from the heating element to melt a bottom surface of the solid mass of wax;
• a heat conducting sleeve positioned inside the housing near the sidewall, and a control circuit for automatically controlling a temperature of the heating element.
