This past weekend I did a lot of cleaning, took all the kiln shelves
scraped, sandpapered and washed them down. Usually when I wash them off
it is with a sponge & bucket of water. This time my neighbor was helping
and suggested taking the hose to them. So that is what we did.
We then brought them back inside the garage (still very damp) and I went
ahead and kiln washed them. I normally let the shelves dry first, but
because of time, I just went ahead and put the kiln wash on them.
That was Saturday..... now Tuesday I went out to start to load the kiln,
and my shelves have turned yellow around the edges!
They do feel cool to the touch, so I brought them outside in the sun (it
is in the 90's today).
So, my questions: What is the 'yellow' and will it hurt??
Can I fire my kiln with these shelves tonight?? Or should I make sure
they are bone dry before I fire?
Did I make a mistake that will cost me in the end, or do I just have to
let things dry before I panic!!
Worried in AZ

The yellow is probably just minerals in the water.
I've seen this happen often on pots after the interior is glazed and dried.
I'd suggest you run the shelves through a pre-heat program or just one
section on low for a while to dry them out before firing them.
