intermediate quantity glazing ???

updated fri 25 jun 04

 

Earl Krueger on mon 21 jun 04


As a hobbyist I have been making only one or two
of an object and a few hundred grams of glaze
which I usually apply by brushing or spraying.

Now I'm ready to scale up a bit and make maybe
a set of 8 matching plates, bowls and mugs.

The question becomes "How do I glaze them?".

Brushing tends to produce uneven results.
Spraying is difficult for objects with handles.
Pouring has not produced an even coating for
me, especially with limited quantities of glaze.
Dipping seems to offer the best solution but that
requires a larger batch of glaze than I want to
commit to yet.

So, how do you folks handle glazing of quantities
between one-off and a full scale production run?

Thanks...

Hi Earl,

I'm not sure what you would call me ( though my husband might have some suggestions). I certainly started out as a hobbyist, but over time I've come to sell most of my work. Yet I'm certainly not a production potter. I just had to bite the bullet and mix up batches of glaze from 4000 - 7000 grams. I would guess for what you're describing, 4-5000 would work. I dip my plates in a flat container, and any more than 5000 grams is more than I need and too much of a pain to move from bucket to flat container and back again. Good luck!

I agree, Earl. Dipping is probably your best bet. T minimize the amount of
glaze you have to make, get some containers that are just a bit bigger than
your pots, and pour the glaze into them to dip. I'd say the smallest
quantity of glaze you'd be able to get by with to comfortably dip that many
pots would be 3000 grams. But glaze is cheap. You don't want to mix so
little that if you have to make them over, you have to mix a new batch.
Make 5000 grams.

Hello Earl,

If you use a large round-bottomed bowl for the dipping process, a gallon of
glaze, or even less, is plenty for a set of dinnerware. If you like the
glaze enough to want a whole set of it, you wouldn't mind having some left
over, would you?

Do you have glaze tongs, to rotate your smaller pieces with? Dipping has
it's own little hazards & tricks to learn- you might want to spend a little
time in the archives. And glaze a few other pieces before the dinnerware, to
get a feel for it.

Good firings,

Earl,

If you are making a whole set of dishes, bite the bullet and mix a bigger
(5000-8000 gram) batch of glaze so you can dip things. It will be worth
it, I promise. If you get creative with different containers to dip
different size/shape items, you might be able to get away with a smaller
batch, but not less than 3000 grams. Glaze is just not that expensive, and
if you're committing to that many pieces, you're going to need to commit to
making that much glaze. Piddling around with little tiny batches will just
be frustrating and give poor results.

My opinion, for what it's worth.

Chris

If you know what recipe you want to use for the glaze on your plates and
bowls because you have already 'proved' it on single items, then mix a
larger quantity to suit your method of application.

If you are not sure, then spraying is a useful way of testing a glaze on
a pot as distinct from dipping a test tile. Spraying an item with a
handle can be a problem if variation in thickness makes a difference
that you don't like. Perhaps on the other hand the variation is
something that you do like. In testing out glazes I frequently make
small quantities, 1/2Kg to 1Kg and spray a bowl or vase to see how it
works on an actual shape. If I then decide to use this glaze, then I
would make larger quantities to suit the method of application and the
size of items.

Dipping can also give rise to problems of thickness variation which may
or may not suit the piece that you are making. Sometimes dipping half
the piece and then the other half with a definite overlap can suit. You
have to progress by testing.

Dear Earl,

Having gone the other way from you i.e. down sizing after being in
production, I work with glaze in one or half (UK) gallon lots, changing
the vessel I dip into according to the shape I'm dipping. Thus for
plates I use a shallow one, for mugs the reverse. For plates I use three
home made wire hooks which fit on two fingers and my thumb and enable me
to grasp the plate by the edges so that I can take it sideways into the
glaze and out again in one smooth movement. I have a couple of JPEGS of
these tools to send you if you would like me to (and anyone else who
would like to see them).

Classes at a clay center are a possible solution or a
cooperative.

Steve.

Yes I would be interested in pictures of your glaze hooks.

Earl.
One of those round plastic sleds that the hardware stores sells works well
for plates and platters.
