Please excuse my ignorance - am a beginner. What are engobes?

Timakia@AOL.COM on thu 20 jul 00


People have different opinions on what a englobe is. To my knowledge and
believe there are at least four non-glaze materials that one can cover (or
partly cover) a pot with to change the surface color or texture. These are
the ones that I think of.
Oxides and stains -- colorants.
A slip -- made out of the same clay that the pot is made out of
or
a slip -- mixed ingredients to cover a wider variety of clays and their
temperatures.
The pot must be soft leather hard when one cover with slip otherwise the slip
will flake off during or before firing, due to uneven shrinkage.

Englobes - mixed ingredients that will have more glaze(fluxing) materials.
This is to make it usable on leatherhard, bone dry and bisque ware.

Terra sigilata -- a very refined slip that gives it a very smooth quality.
One only uses the very fine particles in the clay to create this mixture.
Oxides and stains can be added to any of the last three clay related mixtures.
Paint it on with a brush, dip or airbrush to cover pots
Hope this will give you a kick start on this.

I was looking into mixing up some engobes for a white, cone 6 clay,
fired in oxidation. I would be applying them at the leather hard to
greenware stage. The ceramics books that I have suggest using the body
clay blended with the coloring oxides plus the addition of feldspar. My
question is, how much feldspar? I can't find even a rough percentage in
my resources.

Also if anyone knows of a better way of making engobes I would greatly
appreciate the input. Thanks to all.

I use the following receipe for my colored engobes

wet to leather hard. I use it both on just thrown pieces and fairly dry =
pots.
Just note that you must test it with your clay body and glazes to ensure =
you have
a good fit. =20

5 parts Kaolin
5 parts Ball clay
4 parts Custer spar
4 parts Silica

I use my local spar.

For bone dry or bisque
it is altered to=20
4 parts Kaolin
4 parts Ball clay
5 parts Custer feld.
6 parts Silica

I blend a large portion that I keep dry, and measure out and color what =
I need.

Typical % I use to 100 grams engobe are
1 % Cobalt ox.
3 Chrome
10 R.I. O.
10 any stain
15 zircopax
10 Oldenwalder (iron rich clay)
15 Ochre

or blend any of of the above with 5% rutile to dampen the color.

I also use it just as it is with paperpulp for a binding slip.

Good luck,

What kinda engobes? Vitreous? Non-vitreous?
For under glazes? For salt firing?
For exposed surfaces? What temperature?
What colors? For what claybody?

If you consider a continuum consisting of
clays(slips) at one end, and glazes
at the other, engobes are what's in-between.
In a nutshell: an overfluxed clay, or an
underfluxed glaze. Yeah, there's a little
more to it, but not much.

SLIP...........ENGOBE...........GLAZE
less flux...................more flux

Lotsa recipes in books: Chappell comes to
mind. I like some of Zakin's.

Generally, the term 'slip' refers to a clay in
liquid form, with or without colorants.

An engobe is any of a wide range of non-glaze surface
coatings including underglazes, slips, terra sig,
vitreous and semivitreous engobes, etc. An engobe is
generally assumed to have some modification beyond a
simple slip - fluxes, for example, or low-shrinkage
components (to allow application on dry or bisque clay),
or some such additive. The term does not exclude simple
slips, though.

It's more of an umbrella term - slips are one type
of engobe, but not all engobes are slips.

Janet Kaiser on wed 7 feb 01


Dear Lyn

Engobe is just another word for slip. I believe
engobe is the usual term used for slip when it
is applied as decoration in the US. Terra
sigillata is also a type of engobe, so you may
look that up in the archives along with "engobe"
and "slip".

What exactly did you want to do with it? What
information do you need?

I have three different 30 YEAR OLD recipes to
chose from depending on what they were used for:

1. For using on wet clay:

China clay 25
Ball clay 20
Whiting 2
Feldspar 17
Flint 30
Magnesium carbonate 6

2. for using on dry clay or biscuit ware:

China clay 20
Ball clay 20
Borax 5
Whiting 5
Nepheline syenite 10
Feldspar 15
Flint 25

3. As a glass forming engobe on bone dry or
biscuit ware:

Ferro Frit 3304_45
China clay 12
Ball clay 10
Whiting 3
Feldspar 8
Flint 12
Tin Oxide 10

The colours in all three are achieved by adding
:

Blue: Cobalt oxide
Blue green: Copper oxide + Cobalt oxide
Green: Copper oxide
Brown: Iron oxide
Black: Iron oxide or Manganese carbonate +
Copper oxide + Cobalt oxide
And I guess modern "stains" may also be used?

You have to test quantities yourself, but as I
remember anything from 0.5 to 3 of any one was
enough. Watch the cobalt and copper oxide
though - a little goes a very long way.

I am sorry if any of these ingredients have
fallen from favour because of any health hazards
or perceived risks. As everyone knows, I am not
a practising potter these days and for all I
know they may now be considered taboo or even
unavailable. Please check with someone who knows
all the health and safety rules before using or
just wait for howls of outrage over the next
couple of days. For example, the Manganese
carbonate to achieve black is no doubt one
ingredient many potters would not touch with a
barge pole...

Indeed I had a fourth recipe for a glass forming
engobe. As I remember, it was truly beautiful,
but contained a whacking 45 white lead, so I
would get shot for even mentioning it here.

Hope this helps anyway?

I have always used the term "engobe" to refer to slips adjusted for
application to bone-dry or bisque-fired wares. When I just say "slip" I
mean the stuff for application to wet or leather-hard work. I know that
many other people in ceramics use the terms the same way. Wish we could all
agree on this one way or another.

Thanks to everyone for pointing out the EXACT
difference between a slip and an engobe. Isn't
the English language wonderful? 101 words for
the same thing... Well apparently not in this
case. Just two and depending on where you live,
what you understand to be the difference.

It may seem picky, but I stick to my original
supposition that an "engobe" is the term used
for a slip used as a decorating element IN NORTH
AMERICA. It is an American term. Just as you say
bisque and I say biscuit, you say pitcher and I
say jug, you say majolica and I say delft...
(Oops! Forget I said that Vince! :-) Yes, we are
divided by our common language yet again.

Although why a word of French origin suddenly
pops up across the ocean is another interesting
question. Maybe the British were more cautious
about using a word which sounds like slang for a
parcel of phlegm or an open mouth (i.e. gob)?
Who knows?

Whatever the reason, here in the UK a slip is a
slip is a slip. Whether casting slip, sticking
together slip, spoose slip, trailing slip,
painting or brushing on slip, dipping slip for
sgraffito, decorating slip for marbling, hakame,
feathering, etc. etc. We very rarely see the
term "engobe" outside books and catalogues.
Indeed the only person I know who uses the word
"engobe" is from Lithuania and so it does not
sound pretentious when she does.

It may all be confusing for beginners, talking
about slip or when in a shared workshop with
many different buckets of "liquid clay"
mixtures. For example: "Slipware"... Do we mean
slip cast (moulded) ware or slip decorated work
of certain folk traditions? Further definition
is usually needed.

Several have spoken up (on and off list) for
using "engobe" to mean a slip which has a lower
shrinkage rate and less clay content. That is
fair enough... Seems reasonable to me, BUT what
do you think? Is an added term and definition a
help or a hindrance? If it causes confusion, I
personally have my doubts.

For example Snail S. does not agree that a
"simple slip" could be classed an engobe and yet
something I may consider a glaze (a vitrified
engobe) can be...

> It's more of an umbrella term - slips are one
type
> of engobe, but not all engobes are slips.

So if one accepts the definition of an engobe,
how are we going to separate that from what is
considered a once-fired glaze? A matt glaze with
a high clay content could be counted as an
engobe or a shiny vitrified engobe could be a
classed a glaze.

I am aware of the materials Rhodes listed for
inclusion in engobes (clays, fluxes, fillers,
hardeners, opacifiers and colourants) versus
clay + water + colourants in a simple slip, but
quite honestly doesn't the ordinary workshop
slip sometimes get doctored for the use at hand?
Say for dipping a series of pots? How often do
potters change their standard slip mixtures?
Once you have what you use for various
applications sorted, do you test new slip
(and/or engobe) recipes regularly?

BTW Lyn is apparently looking for a black
slip/engobe for her sculptural work. I presume
that would mean either for bone dry or biscuit
work. I don't know whether painted or dipped...

Snail -
As Joyce pointed out (from Hammer's definition), an engobe (pronounced
"on-gobe") is between a slip and a glaze. It generally has some calcined
kaolin added to reduce drying shrinkage, so that it will adhere to bone-dry
or bisque-fired wares, and it often has a little more flux, to insure good
fired interface with the claybody. So it is not an ordinary slip, and it is
not a glaze. There are such things as vitreous engobes, and the distinction
between vitreous engobes and matt glazes is indeed fuzzy.

Brian -
Please sign the bottom of your messages with your name, so that you can be
properly addressed in the reply.

A glaze has more flux. In ceramics and glass there is a continuum from
refractory brick bodies at one end to pure glass at the other end. Glazes
have enough fluxes and glass formers to create a complete glassy phase
resulting in a fused material. Slips and engobes do not. But as I
mentioned, there is that animal referred to as a "vitreous engobe" and I am
not sure where it belongs. Why not just call it a glaze abnd avoid
confusing the issue?

Not in this case. As far as I know, "slipware" universally means
slip-decorated wares, usually from the grand British tradition.

How in the world could it cause confusion to clarify meaning?

No, (and of course this is just my opinion) all engobes are slips, but not
all slips are engobes.

Good point. Seems to me that the term to be eliminated is "vitreous
engobe," because it is in fact just a matte glaze.

Clay vitrifies too. The difference is that glaze is more of a fused
glass structure (more fluxes) and the engobe is still more related to
the clay that it is on. (IMHO)

Pronunciation: ON-gobe

'en' pronounced as in 'encore';
'gobe' rhymes with 'robe';
emphasis on the first syllable...

A glaze is, as the name suggests, glassy.
That doesn't necessarily mean shiny, but
only that the particles are fused into a
glass-like compound. A glaze can be very
matt-surfaced, but if it's fully fused,
it's a glaze.

There is a class of engobes which is called
'vitreous engobes', and they come very close
to being true glazes, just as some 'dry',
stony matt glazes come very close to being
engobes. There's no clear dividing line,
just a continuous range of relative
vitrification:

SLIP <----------(ENGOBE)-----------> GLAZE

An engobe isn't necessarily just a slip with
fluxes added, as I may have implied earlier.
That is a common variety, though. An underglaze
is a classic type of engobe, and perhaps the
most widely used.

Engobes are also formulated for other purposes.
They may contain very little clay, and include
a variety of other ingredients to suit the
ceramist's specific purpose.

(Some engobes are only engobes in a particular
temperature range. If fired high enough, they
may melt sufficiently to become a glaze.)

-Snail

Cindy Strnad on fri 9 feb 01


My understanding of the term engobe puts it somewhere half-way between a
glaze and a slip. It is applied to bisqued ware, contains more ingredients
than a slip, but more clay than a typical glaze. It may be more or less dry,
but it isn't glossy. It is more slip-like than a glaze and more glaze-like
than a slip.

Tangelos are part orange and part tangerine. They're easy to identify (and
quite yummy). Engobes on the other hand . . . well, they seem to occupy much
more of a gray area. Kind of like someone in the middle range saying, "Do I
look fat?" Well, maybe or maybe not. It all depends on your perspective.

This complication between slip, slip glazes, engobes and glazes has no doubt
caused many potters some confusion.

If we just look at a gradual increase of clay towards the slip end and an
increase of silica towards the glaze end of this spectrum, it all makes
sense. Like the Eskimos and snow, we could have 40 different words for each
variation, but looking at the problem as a 45 degree straight line graph
between two points make more sense, IMHO.

As one who is trying to be a once firing potter, I can see that one
substance, something between the two extremes of slip and glaze, could
satisfy my needs for decoration and vitreous finish in one go rather than
two. This is especially important if keeping ware at leather stage is
difficult. At present, here in the UK, with rain almost every day, going in
and out of leather stage for each slip and then for each glaze is a doddle.

But it might be more difficult in a summer drought.

Sorry about this, but I'd suggest my article "Showing Your Slip" in the
fist issue of Potery Making Illustrated.

Howewver. Engobe is the French word for SLIP and very much used in
earlier days when slip still was principally the stuff used in casting.
Then we had confusions such as "What engobe do you use for slip
trailing?" Today some people still call engobe a liquid made out of
clay used for decoration IF IT IS MOSLTLY CLAy and slip for those engobes
with much of other stuff. All the books give recipes. for dark slips you
can simply dissolve some throwing clay in lots of water, sieve it to
eliminate all grains graininess etc, and test. Then test with
colorants. The thing you are testing for is fit on the body, and how
your glaze fits over the slip. Be sure even if the slip fits well on te
bisque to high fire to your temp--just the clay and the slip, soak the
test tile and make sure the fit is so good that the slip will not be
"pried off" by hot water. (Happened to me once in 50 years, but don't be

I don't often use glazes, per se. I do sometimes
add extra flux to my regular engobes, and when I
do, I call them 'vitreous engobes'. It's really
more a reference to their ancestry than their
nature, so if you want to call them 'matte glazes',
go right ahead! (Sometimes, they ain't so matte
anymore, either.)

Lili's suggestion that Engobe is French for Slip is intriguing. So I did=
a
bit of research. What I found was even MORE intriguing:

engobe Engobe Engobe

How 'bout dat!

Sorry about this, but I'd suggest my article "Showing Your Slip" in the
fist issue of Potery Making Illustrated.

Howewver. Engobe is the French word for SLIP and very much used in
earlier days when slip still was principally the stuff used in casting.
Then we had confusions such as "What engobe do you use for slip
trailing?" Today some people still call engobe a liquid made out of
clay used for decoration IF IT IS MOSLTLY CLAy and slip for those engobes
with much of other stuff. All the books give recipes. for dark slips yo=
u
can simply dissolve some throwing clay in lots of water, sieve it to
eliminate all grains graininess etc, and test. Then test with
colorants. The thing you are testing for is fit on the body, and how
your glaze fits over the slip. Be sure even if the slip fits well on te
bisque to high fire to your temp--just the clay and the slip, soak the
test tile and make sure the fit is so good that the slip will not be
"pried off" by hot water. (Happened to me once in 50 years, but don't be
trusting.0

Allo Jimmy,

I did the french and german parts of this dictionary.
My german version was corrected by an international ceramics
consultant residing in Germany.
Good to hear that the dictionary was helpful to you.

Later,
