Hey Lee,

Yes, like Robs and one I saw from Laguna. I have an opportunity to use a mixer so I thought I would mix some up for tea bowls. Yes, I know Rob, really enjoy his work. Maybe I will email him and ask him. Awhile ago he and were trying to locate the diffusion burner that Sensei Shiro Tsijimura uses on his anagamas. He said he found the company but had to reply--last I recall. Working on trying to get to Japan.

Do you mean like Rob Fornell's black body?

See the rest of Rob's work here (tell him I sent you ;-) ):

I have basalt body recipes from the Kansas City glaze notebook. There
are four of different temps. They all have manganese in them. You
can buy them ready made here at Joyful Honda. If you make it out this
summer, I will show you. June2006@Mashiko.org

Hi Tony,

Not a problem on your hands or in your mouth - it's the fumes and dust that
can get you.

Some pottery clay makers will not even make manganese bodies any more - I
would certainly not recommend them to anyone - but if I did I would make
sure they understood the danger and how to avoid it.

Firing down in reduction would be one way to do this - John Neely does it
that way - just don't give a high enough iron containing body the chance to
reoxidize.

Just stay over the ignition point of your fuel so you don't blow yourself up.

Andrew,

Hello! I am a student at Berea College. I am wanting to create a black clay
body. I saw this response on clayart, and was wondering if you could share
your black body recipes w/ me? (manganese and non-manganese). Thank you SO
much!

Sincerely,
Carla

Dear Carla Gumpsell,

There seems to be a consensus that avoiding Manganese Dioxide is =
advisable in formulating a coloured body. It is an idea that I support.

If you research the literature you will find the best combination to be =
Cobalt oxide and Red Iron Oxide fired in Electric kiln or an a gas kin =
with excess air. Your own trials will provide information about =
proportions.

If you are to learn anything from this experience you should eventually =
have the intellectual capacity to explain to your future students why =
this combination will work.

I wish you success with your studies.

Best regards,

Ivor Lewis.

Having been out of the loop for a few days; I noticed the above thread
and thought I'd put in a belated comment.
As a good black is mostly Cobalt and Iron it works out as a very
expensive exercise to make a body heavy in Cobalt, especially when only
about 3 percent of the colour is visible on the surface.
Why not do as I do and slip the finished piece in a really good black
slip! the effect is the same, and it's a whole lot cheaper!
