Note: The SC-2 is a small front-loading kiln. Between the ventilation slots in the top of the case and the firing chamber is a space about 1/2” wide.
A. Spilling vermiculite on top of the firing chamber under the ventilation slots is not serious. Nevertheless, to remove the particles:
1) Unplug the kiln.
2) Remove the back cover from the kiln, which is held in place by screws. This will give you access to the area under the slots where the particles fell.
3) Tilt the kiln back until the particles slide out toward the back of the kiln. It may be helpful to work the particles out with a long artist's brush. If necessary, vacuum the particles as they fall out toward the back of the kiln.
4) Before installing the back cover, make sure that no wire is touching an element connector.
