Ann,
I've fired gold & copper leaf at ^04, but these were on bisque and
underglazed bisque (no glost). The leaf didn't burn off completely at that
temp but did leave a wonderful irridescent color. It wasn't the effect I
was after, but I loved it. At a higher temp it would probably disappear.

Lacquerware is generally wood. If you are sure they are clay, then you can
indeed refire them. Gold lustre will burn off over ^018 - but not
completely. Refire very slowly, or you will get cracking. Earthware temps
will most likely not burn off the gold. ^6 will leave you with an ugly
shadow or haze.
On the other hand, if they have been painted, as you say, I wouldn't fire
them at all unless you know for sure what they have been painted with.
Could give off toxic fumes. Burning lustre gives off really awful fumes as
well, if that concerns you.
Why not make your own and decorate them as you please? Some things are just
not meant to be recycled, no matter how cheap the price. IMHO, it's not
worth it to "redecorate" commercial work unless you are sure of what is is.

i'm really new at this, so please don't laugh at me, as someone may have a
way better suggestion. but there is a product that will take gold off, i
don't remember what it is called, maybe someone here knows. it was given to
me at ceramics class to correct some drips that weren't visible before
firing the gold. the thing is, if you rub very hard, it will roughen up the
glaze underneath and take some of the shine off, which may not be such a bad
thing, since you want to reglaze them anyway.

Hello, Ann
That would be an interesting experiment. Many paints, especially higher
quality paints, do have actual mineral content which help them to be the
colors they are. I'm guessing, but I'll bet most all metallic have metal in
them. The organic parts of the paint will fire out, but whether the mineral
portions do or not depends on the firing temp and the minerals involved.
That said, refiring someone else's work is chancey at best. I remember one
lady writing in to clay art to tell her story. She had tried to refire a pot
which her son had used to hold oil--I think used motor oil. She wanted to
clean it by refiring. It exploded in the kiln. I don't know what oil based
paints might do to the chargers, but I'll bet they do soak in. Nearly all of
the really shiny metalics are oil based.
Then, even if you don't have oil to deal with, there's water. I remember
refiring a cup once that had been used for drinking. It was obviously a
porous clay, because a big chunk blew off in the kiln. If I had known that
would happen, I could probably have fired slowly enough to protect the
piece, but you live and learn.
Now, about reglazing a finished piece--it's different with low-fire (which
the chargers likely are), but applying glaze to a vitrified pot is really
difficult. Some folks spray the pots with starch or sugar water, or some
other substance to make them tacky. It also helps to warm them up first.
All in all, more work than starting from scratch. But I would be interested
to see what the gold paint turned into. If you try this project, do make a
saggar for your test piece in order to protect the rest of the kiln.
Best wishes,

There is a product called, I believe, Gold Off, which is used to remove
residue left from lustre firing. I don't believe it is meant to remove
large areas of gold, and would only work if the metallic involved was
lustre. I don't even think it works on all lustres - you need to know what
essence was used as the base.
If the original poster was only interested in redecorating, I'd say save the
time, risk and money involved in firing off the undesirable decorations, and
either throw new or buy bisque and redecorate it. Unless you are really in
the mood for an experiment - then by all means, go for it.

Thanks for all the comments and suggestions. I'm a little surprised at
myself, wanting to do this since I wouldn't buy bisque to decorate, and
basically, this idea isn't all that different, once I fire off the gold. I
have 7 chargers, so will experiment with just one of them, apply several
glazes over the paint, and see if the gold does anything interesting. Will
let you know.

One of our local potters recently pit fired a piece that had been
sprayed with gold spray paint - resulting in a bright red on the
surface after firing.

Hello, all:
Common gold and copper spray paints (hardware store variety) can be used on
surfaces to be fired. Both paints contain copper. My kids at school use it
occasionally to overspray glazes. Depending on how much is sprayed, it adds
a turquoise shade to the glaze in oxidation (any temperature). In
reduction, on the right glaze, copper reds can appear.
