    Alice, one reason (don't know if it applies to your particular case
    though) concerns kilns that have exposed electrical elements inside
    the heating chamber.  These last a long time so long as the element
    material is covered by an oxide layer, which happens naturally in an
    oxidising atmosphere, such as you would have most of the time when
    enamelling. With wax burnout though the wax vapours lead to a
    reducing atmosphere which can give early failure of the elements.
