spraying amaco undeglazes

Gang,
In the midst of preparing my work for sale and I have a question: In this
introductory phase I will keep the glazes choices simple, off white or glossy
black. I am thinking, however, that it might be really cool to produce an
alternate "studio line" with multiple colors. As I'm firing cone 6 oxidation I'm
thinking underglazes would be the way to go.

Years ago I did a figurine project and experimented with the Amaco line of
underglazes. I found the experience really incredible. Their colors are strong
and, for the most part, really dependable.
Hence my question: Has anyoned tried to spray Amaco Underglazes? Their
brushability is great and out of the bottle they are very thick. (relatively) Do
they do well thinned for air brushing?
Years ago, when I first introduced my initial line, I had Ron Nagle in mind
and tried air brushing a clear glaze colored with Mason stains under an cone
6 clear glaze. The colors LOOKED opaque upon application but fired out quite
diluted. I would like to avoid that result again if possible? (Or is that the
nature-of-the-beast with spraying?)

aside: In an ideal world I would glaze my slip cast pots with a rich tenmoku
or celadon but I find the white stoneware and cone 6 oxidation firing not
capable of producing those same rich effects. (At least not without a lot of
work.) The selling point of my work are the shapes and designs. The main line
will be covered with simple glazes, with simple firing cycles, so that they
can easily be put into production. The question I ask above really just alludes
to my desire to also make some pots with really complex colorations to match
the complex shapes/designs.

Thanks so much gang!

Jeff,
In reference to your question:

Has anyone tried to spray Amaco Underglazes?

Yes, I have airbrushed underglazes, usually velvet underglazes with
excellent results. I have to water down the underglazes some to make sure
that I can then use my airbrush without clogging the pen, but with enough
coats I get wonderful colors, full and rich. Often I then apply a thin coat
of clear glaze over these airbrushed colors using a spray gun. I fired to
cone 6 oxidation.

If you have further questions and I could be of assistance you can check my
website and e-mail me.
