Hey everyone,
My sensei wants to start testing some very simply varieties of Shino
recipies to find something new, and I was wondering if anyone might have
some input on these Shino recipies in a wood-fired kiln.
The kiln is a combination Anagama/Noborigama which typically fires for 4/5
days, usually hitting a hard cone 11 (give or take half a cone). The clay
body is mostly a buffish stoneware, pretty heavy on grit and flashes well,
we also have a few reddish bodies to boot.
We were thinking of either Neph Sy/Ball clay or Neph Sy/EPK in either 60/40
or 70/30 mix for either. Just hoping someone might have some experience
eiter with a recipie like this, or some helpful additions, etc... pretty
much anything is welcome, just no carbon trap shinos please.
Thanks everybody.
OK

Hi Owen.
You might find the wood kiln list useful:
WoodKiln-subscribe@yahoogroups.com
I use 70/30 Nep Sy/Ball Clay here in Japan and with my ball
clay (keibushi) no soda ash is required. It is close to Kesler Shino
which is 75 nep sy, 20 ball clay and 5% Soda Ash.
In Japan, the shino is just feldspar, so they don't get
carbon trapping. But even with soda ash American shinos, this can be
controlled through application and drying.
If you are firing for five days, you could try glazes that are
closer to being all feldspar.
Because I get good fire color in my wood kiln on my bare clay and
slips, I haven't been firing shino here in Japan. I am going to run
some tests in my next firing on a John Baymore shino that I converted to
local materials. This is his original recipe, it has no Neph sy or
Spodumene, so I think of it as more "simple":
261-F Feldspar 68.7 (Sub your own Feldspar, try Custer and Kona both)
Ball Clay 17.2
EPK 9.8
Soda Ash 4.3
This can carbon trap. Slow drying on a dry, warm day helps
avoid it. Fast drying or putting it in the kiln wet will increase
carbon trapping, as does glazing on a wet day and then loading wet into
the kiln.

Hello Owen; In the fall firing I used a 70/30, NS/EPK.The results were
nice, good variations in the kiln. I don't use to many different glazes
in my woodfire as the firing gives me so many different variations of
the same glaze. If I have time I'll see if I can get some ditital
images of the results. I fire to a cone 12 in the wood kiln,an anagama,
the last firing went six days, so the pictures may be of some value.
Please keep us informed on your results. I think that there are many on
this list that are interested.
