Ian -
On many glazes including shinos, many people do overglaze painting with just
the pure oxide. I like to use iron and a bit of clear glaze, perhaps four
parts iron to one part clear glaze, and then add water to get thin brushable
consistency. When applying oxide overglaze you only need a thin
application, so it is not like painting glaze. Remember, all you are doing
is adding oxide in order to color the glaze beneath.
Another good option is Mel's tried and true orange/brown overglaze mixture,
which contains iron, rutile, and some clear glaze. It gives beautiful color
response on temmokus, shinos, saturated irons, celadons, oatmeals, and many
other glazes. In that case, I would guess two parts iron, two parts rutile,
and one part clear glaze. Again, add water to achieve thin brushable
consistency.
Both of these oxide stains are great spattered with the fingertips or a
toothbrush to give a nice enhanced visual texture in the glaze.
Hey, experiment away!
Good luck -

The term 'oxide decoration' generally implies that a
recipe is not needed - you really are using just the
oxide, on top of a glaze. Some people add a little
something to the oxide to help it flow, like glycerine,
or a bit of the underlying glaze, to help bind it and
keep it better suspended than just the oxide in water
alone. These don't really constitute a 'recipe' per se,
they're just a pinch of this-n-that, to suit. Many
people prefer just the simple oxide wash, straight, so
see what works well for you, over your glaze.
Come to think of it, you didn't actually mention glaze,
did you? just the clay body. If you are planning to
apply an oxide decoration directly to bare clay, the
effect can be rather harsh unless applied very thinly.
That's why engobes tend to be preferred for this.
And if you were planning to apply the glaze OVER the
decoration, rather than underneath, beware of the
dustiness of the oxide, which can cause the glaze to
peel back and crawl. Adding CMC can help.
