Hi all,
I wonder if anyone knows of a clay body formula for a perhaps wood fire =3D
of high temperature that would be capable of withstanding direct flame. =3D
I made a clay body one time with some Zapotec Indians in San Marcos Mex. =
=3D
that fired for 1 1/2 hrs in their courtyard under tim, dung, gathered =3D
dead tree limbs and old lumber and now I wish I had paid more attention =3D
and asked more questions. I just thought it might be nice to make a =3D
water fountain out of flame proof clay so I could do some sort of water =3D
and fire combination. Maybe make a head of steam out of a stream of =3D
water over the fire, early morning stream...just a thought,
Carolyn under a full Vermont blue moon and shadows that will be under my =
=3D
eyes if I don' t try for some more sleep.

The clay and firing you encountered in Mexico was probably a low-fire
surface (near surface) clay mixed with a temper. The firing was a very low
temperature, just enough to change the clay to ceramic. This low-fired
porous clay is able to withstand direct flame because of it's porosity.
I worked with an earthenware clay for a number of years. Made lots of
functional ware.
Visited a friend who had bought a teapot of mine.
Walked into the kitchen and saw the teapot over the burner of the stove wit=
h
the burner on!
Told the friend the pot was not intended for that purpose.
She had been keeping tea hot for months this way.
This story points out low-fire ware can better withstand temperature
variations and flame impingement.
If you do wish to explore high temperature flameware, here's a link to one
potter's method:

I can imagine that a potter having that formula might consider it
proprietary - it's a good niche! But if I were to ask anyone, it would be
