Yes, I have searched the archives. If it's there, I can't find it. (Has
anyone thought of a search engine for the archives?) But that's a whole
different problem.
I recently saw some white porcelain pottery which had been fired with a
horse hair addition (ya know, those squiggly, black, smoked lines) and I was
wondering if anyone could shed (pun intended) some light on how this is
done. I was told it was fired in an electric kiln. Now I suppose I'll have
to buy a horse.
Life was so much easier when you just had to stick your thumb in a ball of
clay, shape a crude bowl, let it dry, and then paint it with tempra.
Everyone thought that was wonderful when we were six.

Hello,
This is in response to you search engine question.
There are two different places you can find a search
engine for the archives of Clayart. Here is the
address to the one I use.

Hi
I have a student who has been experimenting with horse hair raku.
We fire the pots to about cone 06 -04 . We do some piots with traditional
raku glaze and some pots with nothing on them. These pots are taken out of the
kiln and rested on a nest of sawdust (this gives a solid black area on the
bottom of the pot). We then drop horse hair, one by one on to the surface. Using
a very thick glove, turn the piece slowly, adding the hair. Of course it burnw
away quickly and leaves behind the black lines. This seems to wrok very well on
burnished pieces. We have also experimented with coloured terra sig.

Cullen,
I'm not certain, but if it's the same effect I've seen, I was told it was
done with the squiggly wires from steel wool. It might be fun to experiment
with the wires from other types of metal cleaning pads, too. I sometimes use
steel wool to smooth my pottery, and have produced this effect accidentally
at ^6 electric, though I haven't yet gotten around to doing it on purpose.

James, The Horsehair technique is as follows:
Apply 3 thin coats of Terra Sigilatta to bone dry pot, polishing each
coat when it loses it's sheen.
Bisque no higher than cone 06 or Sig loses shine.
Fire bisqued pot to 1350 degrees F in gas raku kiln....or electric -
(but be careful when removing with tongs that you don't hit elements.)
At 1350, Turn gas or electricity off , pull out pot with raku tongs and
place on softbrick or fiber blanket. Have a few strands of dark coarse
horse tail hair ready. Place the hair on the HOT pot. If pot is TOO
hot, the hair will burn up leaving a sooty mark. The hair should singe
and leave a distinctive squiggy line, when pot is the correct temp.
If pot is too cool the hair doens't do anything. You have a small
window of time to apply the hair at the correct temp. Once pot is cool,
wipe off burnt hair with a damp cloth and you can then apply a sealer,
if you desire.
I purchase black horse tails from a Native American crafts supplier for
$10 per tail. Lasts a long time. In our workshops, we have even used
human hair from a salon and other animal hair. It all leaves different
markings. Remember, it's all an experiment!!!!!!

Cullen,
The horse hair pots I have seen and done were fired in a Raku kiln. The pot
is removed when the glaze on other pots you may be firing is mature. Set the
pot on some bricks, wait a few seconds, and take the horse hair (tail or
mane) and place on the pot. If it is too hot, it will burn too fast and
smudge, in that case wait a few seconds longer. A little bit goes a long
way. A few strands can produce a nice effect. Best used on burnished clay.
I guess they could be heated in an electric kiln to a bisque temp, and taken
out, but I haven't tried it that way.

James:
I have done this only a few times, and with Standard's Raku 239, not
porcelain. The unglazed pot went into the Raku kiln, and when it was
sufficiently "cooked", I removed it, placing it on a cinder block set close
to the kiln. I immediately draped black tail hair from my horse all over it.
This must be done immediately and is easier if a friend removes it from the
kiln and places it down for you and you're ready and waiting to start laying
on the hair. After just a few moments the pot has cooled enough that you
will get no further effect from adding more hair. When cooled to the touch
just brush off the residue. I didn't get as distinct an effect from white or
chestnut colored tail hair.

It's fairly easy to do. (I'm doing a firing this Tuesday at Elgin Community
college). You need a white raku clay, and it helps if your burnish the
piece first.
Then, 1) get some horse hair, 2) heat the piece up in a raku kiln or at
least to raku temperatures, 3) pull the piece out any place it on some fire
brick, 4) drop or place horse hair on the piece. When the piece is too hot,
the horse hair will vaporize, but it leaves very nice shades of gray. When
the temp drops to just right you get the black lines. When the piece is too
cool the horse hair sizzles and sticks, but will brush off when totally cool.

Horsehair raku:
1. Find a horse for the hair.
2. Acquire Ferric Oxide (poisonous)
3. Get gloves, masque
4. Prepare a place to spray pot. Do not place pot on metal. Ferric Oxide
is a form of iron rust and will corrode any metal, so do not use your best
banding wheel. I usually place my hot pot on a brick.
5. Get a sprayer for Ferric Oxide. Mix F. Oxide with water
6. Cotton batting for smoking (you don't want your reduction material to
flame up since you will be working directly with the pot, but you want some
smoking.
7. You may terra sig your pot using any ts formula. This form of raku
looks great on a burnished terra sig'd pot
8. Take a bisque pot. Place in Raku Kiln and Heat. I don't know the part
icular temperature, or if it matters. I usually go by the atmosphere in the
kiln.
Probably 1500F. If you need to actually check temperature, place a clear
crackle pot in kiln. When glaze on crackle pot melts, your pot without
glaze will be ready.
9. Take pot from kiln with tongs.
10. Place pot on cotton batting.
11. Spray ferric oxide on pot.
12. Add strands of horsehair to hot pot. Horsehair will form webs or
squiggy lines.
13. Good luck. Be careful when spraying the ferric oxide.
14. I find it does no help to place your pot in a container to reduce. You
will lose the effect of the oranges and blue/browns of the ferric oxide. I
find that very little smoking is necessary.
15. Experiment and have fun.

Hi Jim,
Check with Mary O. I believe she has quite a bit of information about this.=
Re
the archives, did you try http:www.potters.org/categories ? I forgot which
industrious soul decided to take on the task of organizing the archives by
subject, but it's pretty nicely done. Give it a try.

James, I have been busy with shows for the past couple of weeks and am way
behind on my post reading,so with 800 or more to go I may find that you have
gotten all the info you could possibly want and then some on the method
called horse-hair firing. This is actually a misnomer because there is no
hair involved in the actual firing. You must first terre-sig your greenware
pot and burnish it , then low fire ^ 10-08 range. As in our American-style
raku process you then remove the glowing hot pot let cool to the point that
it is not going to burst a combustible into flames in short order ( this is
something that takes that "knowing" that we find hard to explain to others)
then apply your horse-hair, which by the way does not have to be limited to
horse-hair or hair period. You are just carbon-trapping into the still
vulnerable slip surface. I know that I didn't explain this as well as some
of our more scientific buds out there but hope it helps. Tasha
