<p>A heat transfer press that includes an upper part which is movable between open and closed conditions; a lower part; a flexible diaphragm; a glass sheet member having an electrically conductive coating on its surface; first and second elongate, spaced, electrically conductive bus bars on the electrically conductive coating and electrically connected thereto; a reflective heat insulating coating over the electrically conductive coating and air evacuating means for evacuating air from between the upper part and the lower part of the press when the upper part is in its closed condition on the lower part. An electric current is passed through the electrically conductive coating, for enabling the glass sheet member to be heated by an electric current to provide heat to sheet workpiece material in the press while the reflective heat insulating coating redirects heat toward the sheet workpiece material to enhance the heating process.</p>
