Chris,
here's my personal recipe for a rusty glaze which works pretty well:
get your bisqueted piece and apply the following oxides/colours - you use a
damp sponge dipped into the powder so that you can apply the oxides fairly
thickly, building up the layers and alternating between the oxides/colours
so that you get different tones:
red-brown underglaze (to give the basic background colour)
red iron oxide
rutile (quite alot of this as it fuses nicely when fired)
a tiny bit of black iron oxide
at the end add a tiny bit of iron spangles, again alternating between this
and the other oxides, this just gives the odd, metallic glint.
fire to earthenware - you may want to go through the whole process again
when the piece comes out as you can build up little crusty, flaky patches
that way.
I will try to remember to dig out a picture to email to you of something
that has this glaze on it.
Let me know how you get on...
Best wishes
Claire
