I recently saw a really neat design in the Encyclopedia of Pottery Techniques
by Peter Cosentino. It's called "mocha ware". It looks like ferns. To achieve
it they're applying liquid containing tobacco and coloring oxide to a freshly
slipped surface. The liquid, known as mocha tea, reacts with the wet slip to
produce organic patterns.
I wonder if anyone has heard about it, and maybe has a recipe for the liquid
and slip, and firing conditions?
Thanks, Paula

I have done some mocha diffusion, and have found two tricks to
be successful. First, the tobacco juice preparation. I went
out and bought a package of cigrette rolling tobacco (Drum, Top or whatever)
I then got out an old coffee can and my camping stove, put about a quart
or so of water and the tobacco in the can and set it to boiling for about and
hour, replacing water when the level got low to keep approx one quart in the can
wonderful to me. After an hour or so, remove from heat, cool and strain the
solids out. Now you can add colorants, oxides or stains to bits of this liquid.
Use as much as you would use when rehydrating stains. I then paint slip, I use
porcelain for nice contrast, on the greenware. Here is a VERY important point--
to it and the results were not nearly as good as tobacco. Hope this helps.

Mocha ware is also found with a blue decoration. In American Country
Pottery by Ketchum, yellowware is illustrated with a basic form in yellow
with a white band sometimes edged with either blue or white smaller bands
and a mocha ware design in cobalt. The notation says that it originated in
England c. 1860. The design is also called seaweed.
Kovel's Antiques Price Guide says: Mochaware is an English made product
that was sold in America during the early 1800s. It is a heavy pottery
with pale coffee-and-cream coloring. Designs of blue, brown, green,
orange, black, or white were added to the pottery. (Mocha also seems to
apply to brown marbelized ware as well.) As I recall, the Bennington
Museum in Vermont has some Mocha ware on display. The original Mocha ware
seems to be pretty pricey according to my price guide book.
If anyone comes up with an answer on technique, I would also be interested.

Hi everyone...I have been doing Mocha ware or Mocha diffusion for about
20 yrs. and always find the stuff interesting each time I do it. I have
taught many workshops on the techn. and learned it from a BOOK called
Surface Designs which mysteriously dissappeared from one of my classes. I
am still looking for a copy if anyone has an extra or can find one. It
is out of print now.Also saw Robin Hopper demo this techn. in a workshop.
I digress...
Mocha diffusion is mixed traditionally with tobacco juice....but I don't
chew...so the secret ingredient is Apple Cider Viniger. Other vins. do
not work.
Mix the ACV with your oxides and touch a brush of the mix to a slipped
surface. The slip has to be WET and freshly applied to the pot. A good
and the best slip I have found is the Universal white slip that fires
from c04 to c12 in oxidation, electric or reduction. This slip can be
colored for colored backgrounds. I do not apply glaze over the mocha
diff. or slip deco but then that is just my way of working.
Mix your solutions to the thinness or thickness you like...its a personal
thing..
Mocha CONFUSION is a lot of fun so have fumn with it.

I don't know much about it, but one of my students wanted to try it, so
we have experimented a little.
You need tobacco soaked in water for the liquid base (seive the solids
out); the colorant is supposed to be manganse (or so I've read), but my
student trried Red Iron Oxide.
On the pot, put a nice fat layer of white slip. It must be extremely
fresh and wet in order to get the fern-like spreading. All she did was
to drip a drop or two onto the edge of the pot onto the really wet slip
and Viola! It "ferned"! She hasn't gotten it right, really, but this is
an early success. She bisqued the piece and it is very chalky, so I know
we haven't worked out the right proportions, but maybe someone more
knowledgeable than I will know the best way.
I hope so; Frances would be so excited!

This one's come up before, maybe a year or so back. I can't find my notes
yet but seem to remember you apply the Mocha "tea" to ware that has been
freshly slipped. The "tea" itself is a mixture of manganese or cobalt
(correct me on this, folks!) and tea, or tobacco (ground cigarette works), or
vinegar, or even urine... for those so inclined. I think the key is that it
has to be acidic? The "tea" is dripped onto the freshly slipped pot, which
is held at a slight angle, and the stuff spreads out in branches or tendrils.
I haven't tried this yet, but I believe the method should be in the archives.
The technique is also demonstrated in Robin Hopper's "Making Marks" videos,
"The Encyclopedia of Pottery Techniques" by Peter Cosentino, and "The
Illustrated Dictionary of Pottery Decoration" by Robert Fournier. (Some of my
favorite resourch texts.)
Hope this helps a litte.

My first time to use this service so bare with me. I did try to send this
earlier but did not have a subject so I'll try again.
I'm looking for the formula for mocha ware. I have boailed the tobacco for 2
hrs. and have let it set for 2 days. I have heard that you need to put
vinegar in with the tabacco juice, but how much, etc. I have tried it befor
with mixed results but would like to be more sucessful with it this time.
Thanks,

Cathy Harris on fri 12 feb 99
Jane,
Some people use things as simple as very very strong coffee, mixed with a
little water and vinegar. According to Robin Hopper, female horse urine is
the best for mocha diffusion! Go figure - has something to do with the
hormones! I've tried the strong coffee and vinegar and it has worked very
well.
Have fun with it!

Jane,
The original Mocha used tobacco-spit mixture. Contemporary Mocha can use
tobacco
Charles Williams on fri 12 feb 99
Jane,
Sorry about the partial reply! My dingbat computer has been doing funny
things from time to time.
Contemporary Mocha technique uses vinegar mixed with colorants such as
manganese dioxide or cobalt oxide. If you can not get the tobacco mixture to
work, try these concoctions.
Hope this is of value to you.

Forget the Tobacco juice, just use Cider Vinegar with your colour, and
drip or trail it onto thick wet slip. Manganese seems to work best.
There have been many posts on this subject, so a trawl through the
Archives might also be useful.

Hell-o Jane,
The Potter's Manual, by Kenneth Clark, says:
25gms finely cut tobacco
1pt water
30gms iron or manganese oxide
Bring tobacco & water to boil, simmer 30 to 40 min., sieve thru 200 mesh
sieve, add iron or manganese. It improves if kept in the refrigerator...
You can make up the tea and add colorants to a smaller portion as you like>
This is a good book to have in your library!!

Does anyone have a recipe for making mocha tea?
I understand it comes from tobacco and an colouring oxide. Elsewhere I
read that it is tobacco and manganese dioxide, but no amounts were
given.
Perhaps the manganese dioxide IS the colouring oxide.
So far I have collected a goodly amount of dog ends from a friendly
local publican. They are now stinking out the workshop even through two
layers of polythene. I have promised the pub, called The Vine, a pot
with the a vine-like growth of Mocha Ware. I have a supply of manganese
dioxide, as well as other colouring oxides. So ready to go :-)
Yes, I could experiment with different quantities and get results,
sometime, but why redesign the wheel if ClayArters already have the
information?
Bless you all and thanks in advance.
What happens to Mocha Ware when smoking is banned world-wide? Is there
an alternative, based on the chemical reactions in crystallography, such
as displayed in moss agates?
For those of us who handle a paint brush like a tree trunk, this Mocha
Ware could be a helpful answer to prayer.

You don't need to get into the disgusting collection of cigarette butts.
Just use vinegar and the colorant, manganese, cobalt, etc You will have to
play around with it. Robin Hopper demonstrated the technique here awhile
back and he poured a slip onto a green ceramic surface and while still wet
would then apply the diffusion material, and he used vinegar. We had to
experiment around before it would work for us.

I, too saw Robin Hopper demonstrate this technique. I can't recall if he
mentioned it, or someone else, but I found that using 'live' vinegar--the
kind available in health food stores that still has the 'mother' in it is
much stronger than the usual kind and creates much better diffusion of the
solution through the slip.

If you go to a tobacco store and purchase a nice smelling loose tobacco it
will produce a fine tobacco tea. A nice smelling cigar will do the trick also.
Use a small handful of tobacco and 12 oz. of water. Just boil the tobacco
in water for 5 to 10 minutes and then drain off the solid material. Add
your colorant to the mixture and it will diffuse nicely with wet slips.

I didn't include the slip recipe in my original message about mochaware
because what works for one doesn't always work for another - it will depend
on your body to some extent and you will have to experiment. However this
is what I find works best, the recipe was devised by Alison Sandeman -
15 Cornish Stone
75 HVAR ball clay (high in silica)
5 China clay
5 Flint
Good luck -
