Cone Firing

Identify which cones you have by checking the label on the box or the printed number at the base of the cone.

Cone 010 is NOT the same as Cone 10. Be sure to note the cone number exactly as it is printed on the cone.

The list of temperatures for each cone number is attached, but you won't need it because the kiln comes with built-in cone-firing programs.

Turn on the Sapphire3D Sintering Oven using the red power switch.

The controller will default to the IDLE screen. The display will alternate between IDLE and a number, which is the current temperature in the kiln.

From the IDLE screen, press the GREEN button (START/STOP or Enter)

Navigate using the RED button (HIGHER or Options) until the display says CONE.

Press the GREEN button to enter the CONE menu.

Navigate using the RED and BLUE buttons to search for the program that matches the number on your cone.

Press the GREEN button to select the program.

Once you select the program, there will be a few options that you will have to set before starting the program.

The display will alternate between "SPD" and "STD/SLOW/FAST". This is used to set the firing speed. Use the RED and BLUE buttons to navigate to STD.

Press the GREEN button to select the STD firing speed.

The display will alternate between "HOLD" and a number. If you chose the matching program for your cone, use the RED and BLUE buttons to set the value to 00.00.

Press the GREEN button to set the HOLD time.

The display will show "START" once you have completed all the previous steps. At this point, the program has been initialized completely, but has not begun yet.

Place the cone in the center of the chamber to ensure even heating.

Close the chamber and ensure that it is tightly sealed.

Press the GREEN button to start the program.
