greetings from snowy snowy anchorage!!
i have a puzzlement and hope someone
can help.
we are using baileys red from john britts book
and millring red from last months cm.
over laguna b mix fired to cone 10 down and cone
11 soft to 1/4. reduction. oh, it's cold out now
and i think the kiln is cooling fast at the
top temp.
and although we are thrilled with the look, when it
comes out of the kiln we get a beautiful RING ,
however, rinse it or wash (add water) and the
ring goes away,thunk.
hmm what's wrong? is this normal? fit problem?
whatever could be the problem?
i appreciate your contemplation of my problem
and any comments are welcome.
tia,
bliss

we've been playing with millring and not had any problems. We're cone 10
solid reduction (copper red type) on Highwater's Hestia. Only thing I could
think of is that there's some kind of fit problem. Have you put it into one
of the calculation softwares and compared it to one of your other glazes?
We always run them BEFORE trying, just to be sure they (new glazes) are at
least in our ballpark.

wetting can cause the ring to disappear for a time....absorbsion in the bod=
y maybe....?

Not necessarily a bad sign. wait...re -test....look for small cracks in the=
glaze....or for a hidden dunt ....maybe possible too.

Get a magnifying glass to help seeing cracks in the glaze. Also you
can sacrifice a pot and bang it with a hammer. If it is a pot with
good glaze fit it will break clean, in relatively straight lines, but
one with poor fit will break in a jagged way, showing that there were
random cracks in the clay itself.
Jennifer
PS you might try the Anderson Ranch red in the Britt book. I think he
lists the expansion of his glazes. Try one with a different expansion.

I've hired Ron Roy several times to help me with glaze fit problems.
Iron Red glazes are a little tricky since it's a delicate chemical
balance that produces the good red, and messing with the ratios in
order to fix a glaze fit issue can wreck the color. But Ron is a

Jennifer....
How right you are! We also have hired Ron to help us solve some knotty
problems. Many on this list don't realize that Ron makes part of his living
as a clay/glaze consultant. He would never say this and has always
contributed freely to this list. But he is gun for hire, and it shoots
straight.
