This is an appeal to our Clayart wood fire experts.
I am going to be a part of a wood firing in October. We are in New York,
and the wood firing is going to take place in West Virginia. Since I am a
complete novice in this area (I have only participated, rather blindly, in
one previous wood fire), I was rather alarmed by the string on shinos. I
understand we will be provided with shinos and slips, but there has been no
mention of glazes. Since some of my pots are functional, I am now rather
worried about the inside of these pots. If I understood correctly from the
various posts, shinos might not be foodsafe or practical as liners. I
wonder if anyone would be kind enough to share a glaze recipe for a liner
glaze, which I could prepare here and take with me. I understand that the
temperature will probably a soft cone 10.
Thank you in advance for your help.
All the best.

Dear Veena:
The shinos should be okay. I have shino bowls that I've been using for 12
years at least. They've been through the dishwasher, etc. and are fine. The
recipe I use is called Graeme's shino and I believe I've posted it before. I
usually apply my shinos quite thin because the one I use give me the peach
and deep red/orange tones that I like, if it's thin.
Tenmokus also make good liners for wood fired pots and often have a good
firing range. There are probably a lot of recipes in the Clayart archives for
both shinos and Tenmokus.
Warm regards,
June

Ive had good experience w/ A Hamada Tenmoku in wood fire. 4o quartz
silica
21 custer feldspar
15 red iron oxide
11 whiting
8 wood ash
5 china clay
Or let the wood & fire create its own glaze.

If you have access to wood ash, try;
40% ash
40% custer
20% ball clay
you can also use the other glazes posted on the list,
cone 10 glazes for Rods Bod, etc.
In mine I just use regular glazes based on cone 9-10.
Just play around!

Dear Veena, I have been using a clear liner that is good in all parts of the
kiln--even the cold, cone 4 and under weird places. Years ago, the late
Sandra Johnstone did some salt fire workshops with us in San Francisco. Her
kiln would range from cone 5 to 10. She recommended just a liner made of
colemanite and water applied THINLY. Now I use Gerstley Borate. Just take a
bag of a few pounds of the dry powder with you to the kiln site. This is
enough to make a gallon or so. Mix with water until you have a thin wash.
Line your pots, and you will have a fluxed glaze in all regions of the kiln.
So, when the kiln has cold spots, my pieces with this liner come out fine and
functional and usually hold water. Its very runny. Use on the insides only.
Some people use Gerstley and plastic vitrox, 1:1 for a less runny liner. The
fly ash will add to its effect, making a nice ash glaze. Sometime the
insides get opalescent (probably from the iron in the clay).
p.s.If you use shinos, however, along with this, apply the shinos first (on
the outside), and then this liner. Shinos don't like glossy stuff under them,
it can come out looking like strep throat. Bubbly. Yuk. This liner has saved
a lot of my pieces in zones where other people get dry glazes. And then they
throw them away. What a waste. Refire anything that is cold, also, in your
cone 10 gas, and the wood effects will be fine. The important thing is
getting pots into the wood kiln and COLLECTING DUST that will melt later.
Keeps things SIMPLE, and inexpensive. Good luck, let us know your results.
Flame on!
