Hi Chris,
Red Iron Oxide fired at ^6 will give you a dark rusty brown. Fired at ^04,
it stays red. Just mix with water (a little goes a long way) and paint it on
green ware or bisque. If you want the dark brown effect, paint it on bisque
and fire to ^6. If you want the red effect, you can paint it on green ware
and fire to ^04 but this depends on how sturdy you need the finished product
to be. I have not tried it yet, but it seems to me that it would be possible
to fire your piece to ^6, paint on the oxide, and refire to ^4 to preserve
the red also. There may be other ways to do it, but I started using it a
couple of years ago when I was taking classes and have been limited to ^4
and ^6 firings using the community studio kilns. Of course we were also
using ^6 clay. Good luck!
Cheers,

Thank you for the advice J and Rebecca. I have tried iron oxide before and
while it gives a rust color, it doesn't quite give the effect I want. I
will test the Instant Rust. I will also test your suggestion Rebecca of
Firng high then low to get more color variation. I will let you know how
it turns out
Thanks Again,
Chris Clyburn

Chris,
Another option would be to stain the work. You can combine (until the
color suits you) the two reds and the orange of the Cerdec line, throw in a
little ball clay and gerstley borate (say, 2 parts dry stain, 1 part each
of the gb and ball clay), mix with water and spray sparingly from various
angles. Especially if you have some texture, the effect can be pretty
nifty. (Practice on something else first. ) I use this on some
non-functional high fire stuff.
Or you could spray on some iron oxide, maybe lightly wipe it off the high
places, and then use the above mixture for some subtle highlights here and
there.

Chris, there is a potter from the Portland, OR, area named Chuck Gluskoter
(and I'll bet I spelled that wrong- sorry, Chuck) who makes pots that look
like they're made of very corroded iron. What he uses to get this effect is
the dirt from his back yard, applied like a slip glaze. How unique his back
yard dirt is, I have no idea, but it's worth a try. Or maybe some kind of
heavy-iron clay with no flux added would do the trick.
Good luck,
Paul Lewing, Seattle

Paul, does he fire ox or red and what temp? I love that effect, but the
only time I got it was using a red clay in a soda firing.
