Yes. Just add some glaze to the bare patches.
If they are small, no 'tricks' may be necessary
to get it to stay put.

Hello All,
I have a few large bowls that have been glaze fired
cone 6 and I'm not sure what happened (possibly was
sloppy with wax resist), but I have patches inside
two of the bowls that the glaze did not take...can I
refire them?
Thanks in advance,
nancy

Nancy,

You can reglaze and refire. The results are seldom perfect. I
understand that in England its called clobbering, a pottery term that
has entered common usage.

I wipe the spot with a damp sponge,
heat it with my trusty torch then brush
or pour the glaze onto the area.
It dries almost immediately because it's warm/hot.

Hi Nancy,
Give it a try. You know that once the pot has been glazed fired, the new
glaze you wish to apply won't stick. There are many ways to overcome this
problem involving glue, starch, hairspray and other exotica. I've tried
them all. The two ways that work for me are, take a small amount of glaze
and thicken it using wall paper paste. Apply it to the problem areas. Or
take a small amount of glaze, let it settle, take off as much water as you
can (this will take some time because you need to let evaporation finish
what the turkey baster couldn't) and then apply the thick glaze to the
problem areas. But first, warm up the pot. Either set the pot in the sun
(if you live where it is hot) or put it in a cold oven and turn on the
lowest setting (50C for me) and wait 5-10 minutes. Get set to burn your
fingers. Refire.

Best regards,

Hi Nancy,

It is possible to repair - just get enough glaze on those patches.

Glazes are going melt more on a second firing to the same cone. Just
because of added heat work. Some glazes will run because of that added
fluidity - and some will look quite different depending on the "balance" of
the glaze. You may want to make sure your shelves are protected properly.

With my Tenmoku glaze I could refire it once - but twice was too much.
