I would like to try using colored slips to decorate some cone 6 functional
ware. I use a buff colored clay with grog. My experience to date with slip
has been to use the slip from the bottom of my water bucket to attach
handsles, stems, etc. How do I go about making slip for decoration. I'm
guessing I would screen the grog out of my body slip--but--wouldn't this
shrink more than the body clay? Is it possible (or advisable) to make a
slip from scratch using ball clay with additives? Any and all suggestions
welcome. TIA Judith

Judith -
This slip works well at high and midrange temperatures. We refer to it as
"All Temperature", but it flakes occasionally at low-fire temperatures.
All-Temperature Slip
Kaolin --------------- 34
Ball Clay ------------ 20
Potash Feldspar ---- 27
Flint ----------------- 19
Total --------------- 100
Plus:
Zircon Opacifier ---- 8

Some companies, like Valentine Clays in The Potteries, UK, have
complementary pairs of clay.
One is earthenware red, for the body; the other is earthenware white for the
slip.
Buy more body clay than slip clay at the same time and you're set for the
next year.
Another company, also in The Potteries, makes the glazes which then go with
these two. They've tested them on those clays as part of their R & D.
So, you then know that you have a matching set.
Do they do this in The States and elsewhere?
It seems so logical.
You then do not need to use a complicated formula or recipe to make up the
slip.
Just slake the white clay and add 10% or more stain, depending on how
strong a colour you want.
More than 18% or 20% stain (depending on the maker) does not increase the
colour, so don't waste further stain:-)

I use slip often, using the same clay and just adding a stain. I also do cone 6 and have never had a problem,. I brush it on when the pot is almost leather hard, the finish becomes part of the pot rather than getting all complicated with stuff that will separte it, and peel off. At first don`t get carried away with colour, experiment quietly. I mix up the clay water, add , usually black mason stain with a touch of cobalt. Never had a failure. I do the same with my blues and greens. Sometimes I screen, sometimes not. Then I carve the next day. As they always say , it depends, but don`t be afraid to try. If you would like to see my results, they are on the SUCAWS site. Good luck, and be brave. Just keep it as simple as possible to save yourself headaches. Lela

I use slips to add color to my pots without having to use and store lots of
different glazes and the chemicales to make them with. Use mainly a clear.
I use the same clay for the slip that I throw with, thin it out and add
either stains or raw colorants and apply it to my pots after they have been
trimmed.
Have never put the slip through a sieve. If I am making enough clay to make
up several colors, I use an old hand held electric mixer (garage sale buy
for 50 cents) to make sure that the clay is the same consistency throughout.
I divide it into several containers and then mix in the coloring additives
with the same old hand mixer, washing off the blades between each color.
Have never had trouble with the color flaking off in the drying, firing or
using the finished piece.
