Hmm, this:
"Smoke firing uses bisqued but unglazed ceramic, usually burnished when the clay is leather hard. It is put in a barrel or pit with organic materials and/or chemicals and lit on fire. The porous clay absorbs the smoke in swirls and flashes. Different organic materials and/or chemicals leave different colored marks on the ceramic."
describes what I was doing pretty accurately, right down to the burnishing. Most of my stuff had no glaze, some had minor glaze highlights.
I mainly did the process to get the great carbon-black color on (in) the clay.
I could post a pic if you wouldn't mind the the hijack!
I just think you should consider a test of my quick way, it might do what you're trying to accomplish.
I did use some oxide solutions as 'glaze' to get a oil-film-on-water effect, which seems similar to your pic above. Maybe try applying it before a second fire, then use my process.
Mike, sorry if I'm coming across as pushy, but I just think the look you're after was the look I was getting. :)
