Interesting point Mel, but I don't fully agree with you.
If for any reason a firing of mine has had to be aborted, I don't renew the cones, ever, and the results are always the same as an uninterrupted firing!
I'm not being a tight-wad, my reasoning is that everything in the kiln including the cones has accumulated the same amount of heat-work, so why change the cones, they'll go on working, and will behave in concert with the content of the kiln as per normal.
Change the cones and the little bit of extra heat-work acquired as you come to
full temperature might, I repeat might, change things the wrong way,
especially if your glazes have a very small heatwork window in which to come out
how you want them, because the new cones are reading from zero, whereas the pots are not.
Get my drift?

this is after the fact.
but,
if you can reach cone packs, and you have
fired them some...replace them.
the cheapest thing we use in a studio/pottery
are cones.
i know that nan may have not wanted to take the kiln
down...get the cones..then, in that case...just re/lite.
but, monitor the kiln carefully.
but, i have seen people trying to re/use them.
g/almighty...how cheap is that?
i have always used the three cone system.
9/10/11
and, i always add one or two extra packs in strange places,
just to see what is going on in the kiln. cones are the
best gauging system you have...use them.
always, and often.
