Claim 12:
13. A sintering furnace comprising:
a shelf insertable into the furnace to support green objects during a sintering process, the objects to include a token green object;
wires operatively coupled to an impedance meter to deliver electric current through the token green object and measure impedance across the token green object;
a support structure on the shelf to support the token green object and the wires so that electrodes at ends of the wires maintain contact with the token green object throughout the sintering process; and,
a controller to compare the measured impedance with a target impedance and to initiate a furnace cool down phase when the measured impedance reaches the target impedance.
