OK, so is this true? And what about firing down? Does this wear out
elements faster as well? Just curious. I don't plan on changing my holding
habit or stop firing down.

PS ^6 for me is 1200C and that's not from any book or chart, just my kiln's
style.

What causes the elements to weaken more rapidly during a "Hold". I don't
see why this should shorten an element's life (measured in "On" hours),
compared to
normal operation.

If the elements and kiln are rated to say, cone 10; but you never take
that high and only go to say, cone 6, the elements will last a long
time, even firing down or holding a soak at the top. Elements aren't
that expensive. You could pay for them with one or two good pots. I
had a friend back in the 70's that did crystalline glazes, and I think
he was firing to cone 10 or nearly so. He was replacing his elements
fairly frequently, but he bought the wire in bulk and even coiled his
own coils.
If you need the soak to get the results, it shouldn't be a major
consideration. I remember when I was a student; we would complain when
a glaze recipe called for 5% tin oxide (instead of say zircopax at a
fraction of the cost). That would often double, triple or even
quadruple the cost of the glaze batch. We had to learn that even if the
5 gallon bucket cost $100.00 or more, it just didn't factor into that
much cost per pot glazed and the difference in the glaze was like night
and day.

"Struggling" to reach a top temperature is hard on an element. If you
hold at that top temperature, you will, indeed, put wear on the element.
On the other hand, if your kiln can easily reach the temperature you are
firing to, holding at that temperature will add only slight wear to the
element.
So, firing to cone 6 in a kiln designed for cone 10 will add little wear
to the elements. Firing down will also add only slight wear.

Hummmmm,
Didn't make the connection between Lauren and you in Dubai, so I didn't
get that time and shipping are the concern, NOT COST. Shoot if I were
you, and since COST apparently ISN"T a problem, I would always have a
spare set of elements on hand. That's what I do at the art center here
and I don't even live half way around the world.
The bulk of what I said still holds true, if it bothers you take out
that one little tiny sentence. :)

Hey Earl,
Did I mention cost in my question? Most everything I use in pottery
costs a
bomb to ship over here. I try not to let it worry me. My time and my
sanity
are the highest priced things I have.
I realized it was a dumb question the morning after I posted it. I do
pay
attention to my elements because re-ordering them from L&L is always
such an
adventure. How many times can they send elements of the wrong size,
number,
etc before they finally manage to ship what I ordered? The whole process
can
take up to two months and three trips to the Dubai Post Office. Not
fun.
Best regards,
Carol

Keeping a spare set of elements is always a good idea. I agree with
Earl.
Carol, in Dubai, mentioned getting the wrong elements. When the spare
set arrives, you might test them with an ohmmeter to be sure they are
correct. You will need to unwind the element and lay it out on a clean
surface, such as a table. Touch the ohmmeter probes to each end of an
element.
Be sure to store the spare elements in a dust-free wrapper.
