Carole -

Our experience with B-mix ^10 is that you need a flashing slip over it when
it is leather hard....... otherwise you do not get good colour.

Does Laguna's ^10 Bmix work well in wood firing? I contacted Laguna, and
they told me they recommended a special Bmix blend, which they call S-3031,
for wood firing. Unfortunately, it is a special order minimum 2000 lbs,
which is way more than I need. They are sending me a 25 lb sample of the S-
3031, which I will try, but I need to find another readily available clay
body to use.

If you have used the regular ^10 Bmix in wood firing, what kind of
color/flashing results did you get on the bare clay?

Any other recommendations for a commercial body for woodfiring? How about
Standard #119 stoneware, which Standard says is good for wood firing?

Thanks,

Hello Carol: I've used Continental Clay's, Stoneware Fireclay in
woodfiring with good results. It takes flash and ash nicely.
Yelllowbanks 401 crude, is my favorite now. It is right from the ground,
so that you have to mix it yourself, it has nice particle size
distribution and you can throw biggish pots with it. Good luck and good
firing.

Carole,
My experience with Standard's 119 is that is seems sort of dead when
woodfired as compared to other claybodies in the same firing. I've seen
this happen in two different kilns. How about using a flashing slip?
Years ago, I remember seeing a couple of woodfired pots made from
Lizella Stone from Highwater..They were really luscious. Anyone else
used this claybody?

Hi Les,

Interestingly, our experience with B-mix is the complete opposite of what
you describe, which makes me wonder why the difference. In the anagama, we
get great color..slate blues, yellows, gold, salmon, rusty red on bare
clay. I also make a slip of of B-mix trimmings to use on a iron-bearing
stoneware that fires to a chocolate brown for an excellent color contrast.
I have found that more intense color comes in zones of heavier reduction,
but even in our oxided zones, the flash color is good though more pastel in
tone. We fire the anagama for 4 to 6 days. I'd be interested to know more
about the kiln you are firing and the duration.

Greetings All---- We have s-3031 B-mix wood fire in stock here in
California. They should have it in stock in Ohio but they May be out of
Helmer Kaolin to make it.

I ll have to get in touch with them and see what the story is with that.

Best regards

Greetings All, Hi Carole

I talked to Matt Morris the General Manager in Ohio and he assured me they
do have S-3031 B-mix for Wood firing in stock and available for sales in
smaller than ton quantities.

It s a relatively new clay and there was just some confusion at the order
desk in Ohio.

Best regards
Jon Pacini

Jon, thank you for your help. Thanks also to all who provided responses,
both directly to me and to the list, on your personal experience with
various clay bodies. It's always interesting to hear from people who have
been there, done that!

Carole,

I had ordered a few hundred pounds of the specially formulated BMix 10 for wood.
Laguna had produced a batch of 2000 ibs to be avaialbe for the wood firing
conference last year. It has a certain percentage of Helmar added to it to facilitate
flashing.

I fired the pots to cone 10 in a 2 chamber naborigama and was really disappointed.

The raw body got almost no action regardless of placement in the kiln. Luckily, as a
safeguard, I applied an Avery flashing wash to half of my bisque which produced
beautiful results.

If you ask me, I wouldn't bother with that clay body and instead just get some reliable
flashing slip recipes.

Best,

Hi Carole,
I don't do wood-firing but my local clay supplier, IMCO, has a clay
body they've formulated for wood-firing. It's called Concow Wood Firing
Clay and you can look at their website at clayimco.com for more
specifics. I believe it contains Helmer Kaolin to enhance its flashing
quality.

I use it for cone 10 reduction firing in my gas kiln and I have to say
that some of my glazes take on a slightly warmer or more interesting
color when put on the Concow as opposed to a white stoneware that i
also like. Plus I really like how it throws. They also make it with a
30 mesh sand added.

No affiliation with IMCO, just throw a lot of their clay!

Hi, Has anyone else tried the woodfiring clay that Sheffield is offering? We
tried some pots in last week's firing, just opened the kiln today, and it seems
to toast up very nicely, rather dark in some places, Hard to describe, I don't
have photos, clay body turns from white to an almond color to a walnut to a
dark red brown, almost shiney. It is nice to throw with also.
