rubbing oxides into impressions

Okay, at the sake of asking too many (stupid) questions in one day, I do =
have
one more. I have tried to rub red iron oxide a number of times into some
impressions. I have just added enough water to make it pretty thin (thinner
than a glaze), but my problem is I can't seem to control the application. I
have been applying with a sponge and then taking a wet sponge and trying to =
rub
off the excess. Is there a better way?

Diane I have at times impressed printing plates into clay. I bisque them and
brush on a few layers of glaze. When the glaze is completely dry I use a
stiff hand brush to remove all high spots. They fire well with distinct
white and color sections. I have had to touchup and refire large areas of
color. Printing and line art work well this way.

I always mix in a little Gerstley Borate and bentonite to the oxides....then add
water. I brush it onto a bisqued piece and damp-sponge wipe it off.
Works for me.

Diane-- I'm sure you are going to get several good suggestions on how to
accomplish this. And. they may be a lot better than mine. If i knew in
advance that i would try to design a surface, carve it, i would brush a coat
of wax resist on the pot while it is still wet..and then carve. That way,
the uncarved portion would be protected from absorbing the oxide/carbonate.
And. the wax resist would burn off during bisque firing.

Diane - you could also add a little EPK to your iron oxide wash (start with
half the amount of Iron) - add water to the consistency of almost opaque
watercolor (stoke it over newsprint to check this) - brush it on bisque,
wait a minute, and rub off with a damp (not wet) sponge.
