dripless spouts?

updated thu 17 may 01

 

primalmommy@IVILLAGE.COM on sat 12 may 01


So I learned to pull a spout and was quite pleased with myself. Then it occurred to me that it should LOOK nice. So I worked on that for a while. Now I'm determined to learn how to make a dripless spout. I read Ivor's article and puzzled at some clayart references to finishing spouts but I'm still in the dark. Can somebody explain to me how to shape the edge of a spout lip so it won't drip? Talk to me like I'm five. Thanks!

Kelly,
Simple, just make sure your spout curves slightly downward and is
not too thick. A bit like how a child, and some adults, put their lower lip
when they don't get what they want.

Hey Kelly;

I know that your great grandma or grandma would tell you to rub a
smidgin of fat just under the lip, so the fat will break the flow of liquid
and prevent the dreaded drip!

Hi Kelly,

Dripless spouts are about 1/2 science and 1/2 art. There have been graduate
level dissertations written on the subject that are full of differential
equations and all kinds of gobbledygook. Nonetheless there are some
principles that will help. I summarized what I knew and learned from others
about the subject in an article in Clay Times in January/February 1997. You
can find it on my web site at:

http://www.frogpondpottery.com/articles/dripfree.html

I hope it helps.

Regards,

John

Kelly, there is the method, in theory, of boring a small hole horizontally
from the underneath of the lip through to the inside of the spout. The
science is that the last drip, the one that usually runs down the side of
the pot, is instead attracted into this channel by capillary action and into
the spout again.
I have tried it, but made the hole too large, so have blocked it up with
more glaze and refired.
Has anyone succeeded with this bit of pottery science?
If so, can you forward details of just how you did it with dimensions etc?

Dear Kelly,

I was wondering how long it would be before I was drawn into this =
thread.

You need Pottery Making Illustrated, Fall 1999 (Was it that long ago?). =
PP 14-15. which explains in fairly clear diagrams what happens to make a =
pot dribble and Winter 2000 pp18-20 for how to make them so that they =
will not dribble.

There is something about aqueous fluids which compels them to give at =
least one single drop as a drip. I call it Newton's Unwritten Fourth Law =
of Motion. From a teapot spout this is of no consequence because the =
heat in the pot evaporates the offence. From a pitcher it can be =
embarrassing.=20

A sharp, razor edge cuts the flow and usually prevents the problem.

Get back to me if you need more information.

Best regards,

Ivor Lewis. Redhill, South Australia

I would also add that a lot depends on the user too. I
have a friend who manages to drip and even dribble from
the most dripless jugs, pots, pitchers and teapots you
could ever ask for. I have tried teaching a drip-free
pouring technique, but it is just no good... I suspect
not enough panache from an early age?

Martin,

This was discussed at a North Wales Potter's meeting a few months back - =
I couldn't
remember who, what or why, but was able to speak to Vicky Buxton who told=
us about
it.

She says Derek Emms was talking about it at a North Wales Potters' meetin=
g at David
& Margaret Frith's some years back. Vicky said she thought Derek Emms use=
d this
method in his tea pots, for exactly the reasons you say, and in the way y=
ou say.

She didn't have an idea of dimensions etc but said it should be big enoug=
h to allow
the drip through but not big enough to allow tea to dribble out when pour=
ing. She
said she tried it out of interest, but then never had a problem in the fi=
rst place.
She said it made either no difference or made dribbling worse, but that m=
ight have
been because she paid less attention than she usually did to forming the =
spout.

Normally she cuts the spout straight off leaving a sharp edge which she d=
oesn't
smooth - which i think has already been mentioned here before.

Whether Derek Emms originated the idea she didn't know.

Hope this is of some help.

I believe the hole in the spout (as a "cure" for
dripping spouts) comes/came from manufacturer's who
found that designs which looked good on the drawing
board, actually dripped when made into real pots...
Maybe at the time of Art Deco? Those square and
"modern" shapes not developed from wheel thrown forms?

I suspect the dating of the spout hole technique of
drip control coincides with the introduction of
designers of hotel and domestic ware, who knew nothing
at all about the finer points of making pots! Unlike
previous generations of designers who had worked their
way up from the shop floor, they probably never even
made a pot in their lives... Come to think about it,
they probably drove the old mould makers insane!

And even then, the "hole cure" did not always work... I
owned a square porcelain Wedgwood teapot as a student
in the 1970s which dripped violently. The hole also
filled up with tea goo. This was the era when that
renowned company were looking to the mass market to
keep its head above water... Very much designer ware to
the fore, sometimes by well-known artists, but more
often by the new generation of art school and
university design graduates.

I have only ever seen holes in the spouts of teapots,
not on jugs or other "open" spouts or pouring lips, but
would be interested to hear of any contradictions on
that one.

Derek Emms is now a studio potter, but he lectured in
ceramic design at Stoke-on-Trent and worked closely
with manufacturing companies in The Potteries for 30+
years, so that may well be the source or inspiration of
his technique

Unless... Could it have originated in Japan? Or the
USA, Germany, France? Interesting question.
