using oxides as decoration

I am interested in the use of oxides. Not as colorant in glazes, but
other ways they are used for interesting effects: dripping on or under
glazes, brushing on or under glazes. Can't really find anything on
books about this. Anyone with experience care to comment on how they do
this, and what the effect is? Thanks!

Cindi, try some sgraffigo. You will paint the oxide on a dry piece with a
paint brush and wait for the shiny, wet, surface to dry off. Scratch with a
sharp tool right through the oxide to show the clay underneath. Glaze with a
transparent or translucent glaze. You can do the same thing on a glazed, but
not fired pot.
Spatter wax on the surface and paint over that with a paint brush.
Make masks out of paper (telephone directory) and wet the paper masks. Stick
it to the pot and paint over it.
Just a few ideas. Take care though, oxides are very strong coloring agents.
Unless you want them to bleed into the glaze, do not take more than 2-3% to
begin with. A good idea is to make samples at first to see what you like.
Make notes of what you did and what the results are.
Good luck.
Antoinette.
