I believe that "smoke effects" and a "vitrified body" are fundamentally incompatible. AFAIK you cannot successfully smoke a vitrified body,
or vitrify a smoked one [and retain the smoked effect].
I won't say its totally impossible -- as you can have weak "smoke effects" and a partially "vitrified body" -- but I doubt that it would be worthwhile.
My goal is to have the inside of my ware glazed but have exterior raw and charred looking.
Easy enough to do with a non-vitrified body, but it won't be safely watertight.
- One-shot - Raku with post-firing smoking/reduction.
- Two-shot - Glaze fire normally, then lower-fired smoking.
Which is what Tim Andrews does with some of his work, in his case to produce a refined crackle. http://tinyurl.com/p85klch
If you want a vitrified body, I suspect that you may be limited to things like textured surfaces and oxide washes for the "raw and charred" effect.
