I have had a Skutt digital kiln for 20 ? years. Lately it has been firing hot on the bottom and not even bending a cone at the top. Elements are approximately 5 years old; relays have been changed in 6-7 years; I stagger my shelves; fire to cone 5. I think I do all the right things but I’m baffled. Glazed pots look good but wonder if pots at the top could look better. Any thoughts?
Love your teaching style.
