I always fire ^9 1/2 usually unglazed, and then sometimes paint the clay
with acrylics. It occurred to me that since the clay was already shrunken,
that I could then paint it with underglazes and low fire glaze and fire it
to ^06. I asked someone at the ceramic supplier and she told me she'd done
that and it worked. That way I could have strength, fire with my other
pieces and also get good reliable colors in oxidation. I realize that for
glaze masters this may seem like a waste of fuel for the look of a low fire
piece, but it may work for my purposes. Has anyone else done this and have
good or bad results?
Thanks,
Shelley

I occasionally do this, too; firing to stoneware temps
for the durability of the clay and for glazes effects
that require those temperatures, then progressively
firing lower to apply ^06 glazes, ^018 overglazes, then
'room-temperature glazes' after that. It all depends
on what that piece of work requires itself to be.

Hallo,
regarding low fire glazes on stoneware, - At the Adult ED> place I teach
at we found out by mistake, someone put the wrong glaze on.... We regularly
put e/w glazes (1060) on s/w. Works a treat. Sometimes you get crazing due
to different shrinkages. One student used this to her advantage, very
sucessfully. She sponged on 3 or 4 colours e/w colours on a s/w plate, when
it was fired it was horrible, looked like a bad Saturday night out.
So we put a black e/w on top and refired it, it was wonderful! The black
had sunk into the previous crazing and we got a sort of mock raku!
Students are now intentionally using the wrong glazes to achieve these
effects.
Hope this is of some use/inspiration.
Pat.

I've done it with Gare low fire glazes when I feel like doing
majolica-style glazing on a piece of stoneware (I usually throw
randomly, then decide what to do with it after it's fired). I've had
good results for the most part, except when there's a lot of fireclay in
the stoneware body - then I got crazing.

I see your point...had thought of doing some underglazes with low fire glaze
over that...a lot of heating, and then the glaze may not stick over
that...think I'll try something else.
thanks,

Hi Shelley,
Besides not getting the glazes to adhere as well, there isn't any
problem. But adherence is likely to be a big problem.
The vitrified ware doesn't absorb enough moisture to get the glaze to stick
well. Sometimes people heat the ware to help in application
but as you can imagine, especially with multiple areas of different colors,
this can get old real fast. A related problem
is that if the first coat isn't great you can end up taking off areas of
the first coat when trying to apply more.
