I picked up my very first load of pottery yesterday after the final firing.
They all look great as far as colors and no breakage! YESSSSS! But in glazing,
I did not put on three coats as directed on the glaze container. (High fire
glaze on porcelain) They told me I could refire them after reglazing them.
I've been putting on the glaze again...most of them I only have to put on the
clear glaze but a few I've put the underglaze on first again and then the clear
glaze over that. The underglaze tends to bleed if I'm not very careful...but I'm
getting through that.
My main question is...am I wasting my time or can this really be done? There
were a few areas on the pots that the poreclain came through...in other words,
the glaze was not evenly distriubted on some areas. If you can refire, how does
this work. Does the original glaze that's already been fired "melt" again?
It's harder to reglaze these because the glaze is not being absorbed by a
bisque...
Any thoughts or suggestions are appreciated.
Thanks in advance.

I hope this will help. Glaze doesn't adhere to already fired pieces
as easily because it is not absorbed into the fired glaze.If you add
some Gum Tragacanth to your glaze it should make it "stick"
better.The gum burns away and HOPEFULLY your glaze then fires onto
your pot.Your original glaze will flux again at it's required
temperature( This is where it might shrug off the second
application.)It's worth a try as I know just how hard it is to
discard first pots.
Good Luck

Susan,
Oops I really must learn not to answer questions when my mind has
gone walkabout.O.K.,mind here and in gear.It really helps to heat up
your piece first before reapplying your glaze with the tragacanth in
it.
Take care,
Toni

I have some very interesting pieces I've been experimenting with thanks to
the horsehair someone sent -- oh my that has triggered my creativity!
I have two pieces bisqued in two colors of terra sig -- white on the body,
redart on the lip. On the vase, I also poured redart in the interior, twice. It
isn't polished but it really looks stunning with the lip redarted also. I
haven't horsehaired them yet.
However, I have another piece I did with terra sig and horsehaired just to
test -- a small bowl.
Now I'm wondering -- what if I then fired it high-fire, with a shino? Any
black from the horsehair would come through. I might get some carbon trapping,
and that might be interesting also...
is there any reason I can't high-fire a piece that's been heated to cone 06
in the Raku? Since they're being horsehaired, they haven't been put into a
reduction can.
In fact, the two pieces with two colors were bisqued to 04, but I use a
community studio and I can't count on that happening in the future.
Comments or advice, anyone??

I glazed the inside of some bowls with a white glaze that I had used before
satisfactorily. But this time the glaze came out pretty stony--not nice
inside a soup bowl! So I want to reglaze and refire with a glossy clear
glaze. I think I remember a suggestion that one use CMC to help the new
glaze adhere to the previously fired glaze. But I don't know if the CMC is
mixed with the new glaze before applying or if it is applied over the
existing glaze before applying the new glaze. Help anyone? Thanks.

Gay ,,,
I have used the spray on glue (or Elmer's
thinned with acrylic painting medium)
to reglaze fired surfaces, the tiles
I have been making require multiple
firings and the applied glue left
a few seconds on the pot makes a nice
tacky surface for glaze reapplication
and does not seem to have any noticeable
effect on the refired piece.
You can see these tiles at:
http://s4.photobucket.com/albums/y130/claylady/?start=40
look under tiles. A number of these have been fired several
times
and the glue painted only on areas where additional glaze
was needed.
One Caveat!!!!! Fire in WELL VENTILATED AREA!!!
I have no idea what's in that stuff and it does smell.

Gay,
First see if a thin coat of the clear will adhere to the stoney
glaze. Some glazes just stick where others don't
If it doesn't stick, heat up the bowl and try again. If that doesn't
work, try adding a little syrup to your clear glaze.

What is the outside like? I ask because it sounds like the inside is
underfired. If that is the case, you can just refire - slooooooowly, of
course.
