hi folks.... i have just started spending some time in a studio that
uses a ^10 glazes and i am not used to the glazes.. some of the first
plates i got out of the first fire do not look good..
they need a few accents to make them presentable.... i am used to
working with ^6 or ^06.
My question is ..."can i put some low fire^06 accents on the plates
and will they still be functional? I am worried they will not really
integrate with the ^10 glazes .. anyone have any experience with this
or ideas? maybe it would be better to use ^6 accents??
The one thing i cannot do is refire them at ^10 .. the studio is very
far behind with glaze firing and they are doing only the first time
pots ,,no refires...
thanks as always for you help...

Hi Kathleen, nice to see you on Clayart again.
There are two issues here - technical and aesthetic.
Cone 6 is really not that much different than cone 10. If
you fire to cone 6 you will really be re-melting and re-firing
all the glazes. The cone 6 glaze will likely "melt into" the
cone 10 glaze.
I've never tired it, but it might end up looking pretty good?
A cone 06 glaze, in contrast, will most likely just "sit on top of"
the cone 10 glaze. You are entering an area with serious potential
for aesthetic disaster, so plan carefully.
Also, believe it or not, some cone 10 glazes actually do re-melt
at cone 06. I found this out the hard way when I put some
off-color liver-colored copper red plates in my bisque firing.
This was a suggestion from Clayart, as a remedy to clarify the
color. Well, the cone 10 copper red glaze developed bubbles
that did not heal over. Out of the kiln, they could easily be
broken off to make pin holes, making the plates lethal.
The truth is, as I found out with my plates, it is usually better
to just chalk bad glazes up to experience and make new plates.
So, if you really want to save them, I suggest you just put
one or two in with your next firing, and go from there.

Overglaze enamels are usually fired 720-800 C, & they stick to
high fired glazes satisfactorily. Greg Daly does this technique well.
Refiring pots in a bisque firing is not to be recommended, refiring to
bisque temperatures is another story.
