I post this as sort of a "public service" to other pottery semi-newbies like myself. I somehow never got the message that you can easily paint oxide (and mason stain) washes on top of glazes for a lot of added color or design. The videos below brought this to my attention and I am really excited about the results. It has opened up some new avenues for me. I defer to Richard McColl for a full description but it could not be easier:
Just add some oxides (or mason stains), a little water, and maybe some gerstley borate as a flux -- and apply ON TOP of your glaze for great color and effects. Goes on great with a brush. Make it the consistency of ink. Hard to screw up.
Some examples are at the bottom and here are the videos:
