hey, just my suggestions, but why not try amaco velvet underglazes for great
color under clear glaze. Some new ones even have specs in them. Very cool
looking.
I have airbrushed mason stains over clear and satin matt glazes and
dependning on clay color, of course,, will change the depth of color.
I know this doesn't really answer your question but just thought you might
be interested.

At my school my teacher thought me to add about one spoon of
commercially
made dry engob to 100 grams of commercial stain like mason.
It was possible to work, yet was not really good connected after the
bisque, means you might smear it un purposely.
It was too difficult for me to explain to my beloved students that
applying too much stain would cause disconnecting of the glaze to the
pot, so this is what I did I add 50 grams of stain (mason or family)
to 100gram dry engob. The result was a very rich engob. You can use it
as a thick paint or like a delicate paint. I found out that using
engobs
in raku firing gave better results.
Lately, being a miser, I made my own engob. No! Conard's own engob. I
make 5 k'g at a time and add colorants as I want. OF COURSE if you want
exact results like the last time you should do it with dry powder.
This rich engob works on wet, dry bone dry baked and well done
claybody(bisque).
It solved al my problems, I do not keep stains separately and engob
separately. I fire up to ^6.
Here is Conard Engob as I found in Lana Wilson's book. He has more
recipes but why bother?

Dear Leava,
Some Mason Stains will work "straight" with water
as an underglaze if you spray the top coat. I
think most of them would work if applied thinly
enough. However some of them are very refractory.
If you apply them too thickly, they'll cause the
glaze to crawl, leaving them exposed to the
surface, still powdery and unmelted.
I mix most Mason Stains with Frit 3134 (about half
and half), but most any frit or Gerstley Borate
will probably work as well. I also add a good
dollop of Glycerin to make them easier to paint on
with a brush. You can add a few drops of non-toxic
anti-freeze and that helps with the brushability
as well. (Can't remember the chemical name of this
stuff off-hand, but I don't think the toxic kind
will work.)
I don't use Mason Stains for everything, however.
Iron oxide makes a nice dark to red-brown;
Manganese works well for black (don't breath it),
and RIO mixed with a bit of Rutile makes a nice
blond color. I like the blues, though, since they
*look* blue and I can tell what I'm doing easier.
Haven't tried copper for green, but I'm sure it
would work fine. I treat these oxides the same as
the Mason Stains.
