|Example of vacuuming around elements|
|Example of vacuuming lid without elements|
Check on the kiln furniture – including shelves, boards, supports. Are they kiln washed and without scrapes, scratches, gaps? Has the kiln wash been fired to full fuse temperature? In both cases, clean the used kiln wash off the shelf and renew.
Check on the conditions and placement of the thermocouple.
Check on the elements. Some may be sagging or hanging out of their channels. Use tweezers to bring the coils closer together. This shortens the length of the element and it then can be pushed back into the channel. It may not have to be done after each firing, but checking will catch things before sagging becomes a major problem.
