Hi all...I was thinking of putting some wood bits into my next bisque fire
in the gas kiln. I would like to try and reduce TSigged pots with the
wood/smoke . I would put the wood in the kiln after the kiln has cooled to
a low temp. My questions are....has anyone done this in their kiln and if
so what were the results? Approx. what temp would one insert the wood
pieces into the kiln so that the wood would smoke , or burn slightly? Any
thoughts on this idea?
Thanks. As Always in Clay Peggy

Peggy---I probably shouldn't give advice, having fired a gas kiln only
once by myself---but, after seeing Magdelene Odundos wood smoked
TS pots, I would suggest doing what she does, i.e. put your ts pots in a
saggar and fill with sawdust, etc. She gets some beautiful flashing from
this process as well as lovely surfaces from the ts.

Hi Peggy,
I've introduced wood into gas kilns and gas salt kilns for reduction.
Doesn't seem to cause any harm. I wonder if adding wood would have
much effect on terra sig? I've seen people put terra sig pots in a gas
kiln, in saggars full of reduction materials and this seems to work.
A potter I visited in Mashiko would put ricehull ash on saucers and
then put wadded pots on the saucers. He got nice flashing on the
bottom of the pots that way. I'm going to test using soluables and
wads on saucers for flashing on the bottom. I use salt slip on the
bottoms of some of my pots I glaze with runny woodash. A little salt or
soda ash makes this slip blush pink/orange.

This might sound like a stupid question, but could you not do the same
thing in an electric kiln? Why not?

Sherri,
It can be done in electric, but on the type of elements that we use in
electric kilns, the atmosphere created by the combustibles shortens the
life of the elements.
In Japan, where wood is very expensive and many potters live in the
city, they have electric kilns specifically made to do reduction in.
They have heavier elements that are not as effected by the atmosphere
and a box at the bottom of the kiln where charcoal is burned for
reduction.
The pottery I mentioned who used ricehull ash for flashing fired in an
electric kiln.

Adding wood to a bisque fired with gas to get some reduced terra sigs sounds
like a fine idea. (For one thing, if you don't like what you get you can always
refire the results away next time you bisque). You'll probably want to
introduce the wood while there's still a good strong red heat, so the iron will
be receptive to the reduction you seek. Much under 1800 F. probably won't get
you more than a bit of education. You also might try putting the wood in on
only one side of the kiln, so you can see if the proximity to the flames makes
any difference in what you get.
The length of time for the reduction will affect the results, too. You might
hold it an hour or more.
And you'll have to tell us what happens to the pieces without the t. s. when you
glaze them. You're likely to get all manner of responses about that, but let the
pots tell you.
Hunches are a potter's best friend.

One of the things I learned the hard way re TS is that it's very important
to bisque low 022 or 018 and to final fire low to between 015 and 012. I
build a saggar with old soft brick and use the garbarge routine with citrus
peels, banana peels, mango, etc. dipped into bone ash then applied to the TS
....smaller pots wrapped with purple cabbage with bits of rabit food or any
pet food that contains cobalt (mushy). Then charcoal is placed in or near
pots and layers of sawdust, leaves, pine branches, kudzu...eucolyptus is
stuffed all around and in the pots...also seaweed when we can get it. Be
careful to take the fire up very slowly because all of this organic material
gives off lots of water/steam and can sometimes cause blowouts on pots on
the top. The best sagar we had was when each layer was covered with a kiln
shelf - I think the vapors didn't move as far away from the pots as when I
stack it with 40" high pots. The charcoal gives a very nice black smoking
effect in small areas not the whole pot.
We don't put the kiln into reduction - has anyone ever done so??

Beth:
You asked if anyone puts the kiln in reduction with a sagger firing....
I have built a sagger in a old gas kiln with fire bricks, assorted
combustibles, closed the sagger with a kiln shelf and fiber. We fire with 1
burner (2 lbs) for 1 hour; 2nd burner (2 lbs) for 1 hour; turn both burners
to 3 lb for 1 hour; to 4lbs for 1 hour; 6lbs for 1 hour or 1600; reduce 1"
at 1200 close 1" or glow inside. When you shut off, close completely.
The above is from my notes on the firing.
Also, thanks for the info on ingredients you use for your firings. I have
been known to bring seaweed back to TX from FL and CA.
