I understand this technique was developed by Biz Littell at Laloba Ranch Ar=
t
Center. I found a reference to one of his past workshops here
with an excerpt copied below:

The distinctive application of precious metals combined with the Vapor
glazing technique discovered by Biz Littell is the most innovative and
unique glaze and firing process developed in our ceramic era. Biz Littell
has perfected this process with over thirty years experience in its
refinement. The luxuriant results and opulent colors of Kosai ware are
unparalleled.

This is basically what glassworkers do to
make that iridescent coating on glass.

I was looking at Dan Fogelberg's pottery web site and he is using a process
to make iridescent glazes that are more permanent than raku. Here is a
quote from his Process page.
"Although some of the pieces may appear to be raku-fired, all are fired
using a technique known as vapor glazing. Vapor-glazing is a relatively new
and seldom used approach to ceramic surfaces. After the initial bisque
firing, glaze is applied to the pieces and they are fired again, to
approximately 1940 degrees F. Once the glaze is fired to maturity, chemical=
s
are introduced into the kiln as it cools to about 800 degrees F. The
vaporized chemicals bond with the glaze to produce an exquisite and
unpredictable iridescent surface"
Can anyone tell me where to get more information on this process? Can this
be done in an electric kiln? Will the fumed glazes damage my electric kiln=
?
Thanks,
Judy Smith

What timing ! I just read about that last night in Clay and Glazes for the
Potter - Daniel Rhodes - Chapter 30 - Special Glazes and Surface Effects.

Judy,
briefly
Yes, the vapor fumes are harmful to your electric kiln elements--and i
imagine that it wouldn't be good for the thermocouple either.
From about 1970 until 1990 I fired pots to stoneware temps, glazed with
commercial lustres and and then, when the pieces were a dull red, fumed
with stannous chloride. copper lustre and various gold type lustres provide
those blue red colors, liquid gold shifts in a range of gold tones.
the surface, glossy or matt, is provided by the glaze that's underneath the
lustre--lustre doesn't really have a surface. This process is the same on
medium or low range work.
Works best with a front loading kiln so you can fan the door to move the
vapor around (appropriate mask)
Best,
Jane Aebersold

It has been around for some time. My friend Swanica has been fuming
horsehair pots. Except, she takes the pots out of the kiln to do the
fuming. See some work here. They are a big hit in Japan, where
nobody does work like it:
