Hi!
I am just now returning to finishing up some work in the studio from a 2
yr maternity leave. ;) Whle I was pregnant my husband did a lot of
glazing/fring for me. He left the paint roller in the kiln wash
container and it has a rust like cloud near it. ( have just looked at
it and not done anything to stir it up as of yet) I thought of you all
and was wondering if I had to make new kiln wash and how to dispose of
the old if that be the case. I would rather just mix it up and use it.
Thoughts? Experiences?
Would be nice for the shelves to be touched up and some redone for this
bisque before a glaze fire. Thank you,
LJ (who may in a few years come to NCECA to meet all of you wonderful
people)

Iron is a powerful flux. I would be very cautious about using iron
contaminated kiln wash at high temp.

How much money would you actually be throwing out if you just pitched the
stuff? Alumina hydroxide and EPK just aren't that expensive, especially
compared to potentially gluing all of your pieces to your shelves. Mix a new
batch.

I won't think there's enough iron present to create a problem unless you're
firing to ^10 reduction, then I'd toss it.

Hi!
So could I conceiviably try and scoop out the offending rust color...
And use it? I am firing to ^5.
It is more about the pain of having to figure out what to do with the
old kiln wash than making new. WOuld I just dump the water and let it
dry out on some newspaper or something and toss it? If I let it dry in
the container it is in, I can't imagine it would be fun to clean it out
so I could use the container for something else.
