I read today in Decorating Techniques of Joaquim Chavarria about a way to use
oxides over wet engob. The authour says you need to add the oxides to "boiled with
tobacco water. Does anyone know how much water and how much of that brown
smelly addicting material?

"brown smelly addicting material"
Do you mean tobacco, coffee or our national dish of bread & butter topped with Vegemite (a
concentrated yeast extract)?
If it is tobacco you want Janet K (B&H), Rush (Camels) & I (Port Royal rollies) will empty our
ashtrays to send to you.
You supply the water, we still have a drought going on :)

Hi Ababi: Mocha diffusion was traditionally made with tobacco juice.
However, it is easy to attain the same effect using dark stains, ie
Mason black 6600, dark green, bright blue, etc. and cider vinegar.
After mixing a little bit of stain in with a teaspoon or so of cider
vinegar, gently apply it to a freshly slipped pot, I would normally use
a slip made from the same clay body, but screened so that it is smooth.
Use a paintbrush tip, or maybe an eye dropper, and you can get some
interesting effects. Last session, I introduced this to students, and
we made some slightly coloured slips, pale colours, and the cider/stain
mix and the results were fun. Use a clear glaze over, and the stain
stays in place. I found that iron or manganese based stains, (the
original mocha diffusion was done at earthenware temps using iron or
manganese for colorants), did not work as well as the stains, and that
the best slip was one coloured with about 10% yellow ochre. Cone 6
electric firing, works on flat ware as well as bowls or cylinders.

Hi Ababi,
This is called Mocha ware. I have never made it but according to Kenneth
Clark's The Potters Manual:
"Mocha tea is made with tobacco juice, stale wine or turpentine, or a
cobinations of all three, with colouring. It has been suggested that citric
juices, coffee, the juice of hops or tansy asssit the reaction fo the tea,
so there is plenty of scope for experiment.
Recipe for mocha tea:
25 gms finely cut tobacco
1 pint water (that would be 20 fluid oz or 591.2 ml)
30 gms iron or manganses oxide
Bring the tobacco and water to the boil and allow the mixture to simmer for
30 to 40 minutes. Sieve it through a 200 mesh sieve. Add the iron or
manganese oxide and resieve. If the tea is made in advance, it must be
resieved before use. It improves if kept in the refrigerator.
An alternative method is to summer the tobacco in half a pint of water,
seive it through a 200 mesh seive and store the tea in a screw top jar.
When it is required, decant a small quantity in a shallow dish and add
whatever pigment you want. "
Hope this helps. Just don't mistake it and drink it!
Best regards,
Carol

Don't bother Ababi; organic vinegar works as well if not better than
tobacco water.

I meant the national food of east Carolina I belive was adopted by the first pilgrims to
south Alberta mainly by the pioneers of West Dakota - in their Capital city West
Wichita was as well known restaurant called Bombay, was run many years by the two
Bombay brothers that immigrated to West Wichita from Australia. The story was that
they used to add Australian spod to their local gourmet food to make you high. I think
that they took their drug supplier to court as he sold them Canadian spod that caused
the costumers bad mood and they had to close the restaurant

If you will do some research--I believe that tea will also work.

In Jeff Zamek's book "What Every Potter Should Know," chapter 20 is
devoted to dendritic slip decoration -- using a combination of apple
vinegar, tobacco, water, and a colorant. I've tried it and it's kind of fun
watching the tree-like branches form. He says: "The term dendritic slip
describes tree-like, fine line dark patterns of slip applied on contrasting
light color clay background, resulting in what looks like a detailed network
of tree branches. Dendritic slip decoration was originally used on some
groups of mocha ware which were of type of refined, functional, red
earthenware. The name is derived from Arabian mocha stone which has a
similar "tree" or tentacle pattern. Mocha ware was produced for more than
165 years in Britain, and to a lesser extent in North America and France.
In later periods, white earthenware was also decorated with distinctive
dendritic design patterns. British mocha ware pottery was exported as early
as the 1770s."
He says the technique can be used on any temperature range surface, but
you need three things: a reliable clay body formula; a base wet slip formula
that fires to a color that contrasts with the dendritic slip; and the
dendritic slip. Then he gives the formulas. They're for low-fire, cone
06 - 04, but we've used it on cone 6 with good results.
Thank you to everyone who gave me some thoughts on pottery floors. I've
started clearing out the crushed stone and will use the dirt floor unless I
find it necessary to pour concrete.

Thank you Sue for this long answer (that I read all the way).
I am not sure if I like the Mocha ware but I am sure it will be a wonderful excitement to
my pupils.
However it reminds me of the technique I had used to excite children: On a wet
excellent - quality wet water color paper, I gave them food colors. With ear cleaners,
they made drops of colors, than the next color and got stars and "flowers". They were
amazed.
When I will be done with my crystal glazes tomorrow or the next day I shall make
some tests -Who knows I might reproduce my water color success- if not the
mocha wares will be fine too!
