My kiln shelves...

My kiln shelves are flaking off on the edges creating kiln trash.

The flaking is probably a loose kiln wash. As you apply kiln wash to the shelves, wipe the edges before the kiln wash dries. Kiln wash tends to accumulate around the edges of shelves and flake off later.
My kiln lid is cracked and drops dust onto glazed ware. My kiln usually takes 10 hours to fire.
