I was meaning to ask you about your colored porcelains.
then next step of my work will be experimenting with white bead on
white clay, black on black, and colored clay attachments.
Do you find shrinkage differences depending on which stain you use?
It has been suggested to me my colored porcelain will sharing at a
different rate than my uncolored, thus making my attachments not fit
well.
Also, I was under the impression I'll need to add 20-30% stain to my
clay body to get really deep color. Your thoughts?
If the colored clay thing doesn't work out, I'll probably color slip
and paint it on, but I really wanted to try coloring the clay.
Your thoughts? =20
I adore you work, by the way. I recently saw work from a british
potter who was using a similar technique. If I can remember her name
and where I saw it I'll pass it along. I was pretty blown away by the
whole process.

See if you can lay your hands on a copy of
"Polymer Clay Techniques Book" by Sue Heaser. A good section on beadmaking,
and an awesome section on millefiori construction. I bought it for the
section on millefiori, and found the construction techniques translate to
porcelain as well.
Hope that helps,

With all due modesty, (really) I would like to say that I have written an article on this very
subject which will be in the next issue of Clay Times. I submitted a lot of images but I
have not seen the article so I do not know how many made it in.
I have worked with colored porcelain for at least twelve years now and am always happy
to advise anyone whenever I can.
Soon ( well, only in the sense of timelessness ) my website will be done and on it I will
have several pages of process images and technical idetails. Right now I only have the
beginnings of images and such. ( it's been a busy year ) All you colored clay people can
bookmark it and check in from time to time.
Chris Campbell - in North Carolina - You are allowed to nag me and holler at me to get
those images up !! I will forward all messages to the web culprit ... aka ... the guy with the
studio 'jobs' who lets me 'play' with clay.

I use about 3 tablespoons of black Mason stain to about two pounds of clay
and it fires nice and black. I have not had any shrinkage variation problems,
and because of what I do with the colored clay, I think I would if it were a
problem.

Lois -
I do not know who you were asking your colored clay questions of ... myself or Vince ....
but I will attempt to answer from my point of view .... I work very loose and 'close enough'.
Vince is much more precise and methodical than I ... so he can present another
wonderful point of view.
Once you start adding colorants you are messing with the shrinkage rates. I have
solved this in my own work by slowing down the drying process to weeks rather than
days. I picked this trick up from another porcelain artist who dries his super thin work for
nearly a month in a damp box ... turning them every day. My last batch of vases dried this
way did not have any cracks ... so yes it is worth the wait.
When I attach things I use a vinegar water with light scoring ... I use a baby's
toothbrush ... and have the clays at the same dampness. I let them rest in a damp box
and dry as slowly as I can.
I am lazy so I use the most stain my clay can hold when I mix my base colors. It is easy
to add white later to bring out other shades. The mixed clay lasts for years if you wrap it
properly and check the dampness every few months.
For all of you reading this who have not tried coloring clay, I highly recommend it as a
way to pass a chilly January week. Just buy one bag of porcelain, three basic stains such
as mazarene blue, praesidium (sp) yellow and a lovely pink ... make the base colors with
about 10-15% stain ... then by mixing those colors with each other and white you can
make greens, violets, peach ... then make some patterns. These can be checks, stripes ...
or a lemon slice ... or a heart ... or a flower ... anything.
You can lay the thinest sliver of these patterns onto almost any bowl or tumbler or
vase or mug to add a spark of colorful interest. When you are working with such a thin
slice it usually adheres well to a wet pot without any need to score. If you wrap them well,
your patterns will keep for years.
Chris Campbell - in North Carolina - sold out for this year ... shipping out the last items ...
can't wait to try my new ideas next year !!

Lois -
I don't know whether your reply was directed to me, because you didn't
indicate, but I'll try to help if I can. When using Mason stains, the
difference in shrinkage rate is less noticeable than when using oxides.
Generally, a black or dark brown stain will shrink a little more in high
fire than one containing other colorants with less fluxing power. This is
one of the reasons why in all of my colored clay work I only use thin
surface laminations. I have never had any luck with neriage, where the
colored clay goes all the way through the piece. I'd like to learn how to
do that, because there are certainly people around (Michael Haley, Susie
Segal (sp?) Debbie Freed, Beth Forer, Thomas Hoadley, Marion Gaunce, Curtis
and Suzanne Benzle, Dorothy Fiebleman, etc.) doing great high-fired neriage.
You only have use such high percentages of stain at low-fire temperatures.
The higher you fire the work, the less stain you need to get saturated
colors.

My question was directed at Chris, although I'm glad Vince answered as
well. Vince, why didn't I know you used colored clay?!
I have always been fascinated with colored clays - porcelain in
particular, as I love unglazed porcelain. I recently discovered the
work of Susan Nemeth (the british potter I mentioned in my post) and
was completely blown away. In Ceramics Review a few months back there
was a lengthy article, which included a detailed photographic
walk-through of her process. =20
I look forward to experimenting. By the way, Chris, I started to use
Magic Water instead of vinegar, and it is indeed - magic! I have not
seen an attachment crack in weeks. I like the baby toothbrush idea.
I use a mascara comb.

Lois,
Hell yeah! (Oops, sorry Mama) Vince has some examples of
that on his website fer sure. I also ran across a rather=20
detailed article in CM (80's?) about Vince and his colored
clay technique. I wish I would have made a copy of that=20
article. I'll try and get the biblio on that if you want,
Lois.

Hi Chris,
This is very elementary; do you take the porcelain and dry it out and then
figure the 10-15% stain additions, wet all and mix? Or how do you mix up
colored clay?
Best regards,

My answer:
I put the mason stain in a plastic bag ... add enough water to make a creamy solution.
Then I knead the color into the wet clay ... just store bought clay straight from the bag.
If you add the water slowly, there should not be any dust but it might be a good idea to
put on a mask anyhow. Use latex gloves while kneading. You want the colored clay to
be soft enough to knead without hurting your wrists ... like cream cheese maybe.
My website .... which is not really done yet ... ccpottery.com .... will have instructions
and images and as time goes on..... I am hoping to show how to build patterns then how
to make things from those patterns. Bookmark this site and visit it occasionally to see
what is new. NAG me if I am not going fast enough for you !!
Chris Campbell - in North Carolina - contemplating doing a workshop .... yikes !! Yet
another proof of the saying ... 'never say never'!

I CANNOT believe that I have THREE mason stains good at cone 10 and it NEVER
occurred to me to try mixing them!!! :)
Thank you.
