My computer has given me a heck of a time this month. I have been
off-line far more than on-line/ Unable to follow up on stains.
Regarding stains, in what proportions does one mix stains? Water to
stain or other chemicals. Is it done by weight??
I found a couple of good ones in Chappells book. But the only thing give
is dry ingredients and not even a sugestion as to how much water to use.
Is the amount of water determined only by how intense one wishes the
stain to be. or how opaque? In other words - a lot of testing?
These Chappell stains are a nice color but very flat. Is there a way to
give it some life. A little frit perhaps? If so how much. Or how about
simply mixing with a bit of glaze? Again, how much glaze.
I need to spray these stains. Any problems in doing that?
Any suggestions would be appreciated.

Give the new technology a try before you test stains
for the next three months.
Buy one jar of velvet underglaze, a micro-fine pigment
that has already been fired. Spray it by eye, so that
it looks like you want it and fire it.
If you want darkness, use the red-brown. For color,
use medium blue, deep yellow, red, white and jet
black,
and mix as you would regular cold paint and apply to
where it looks good to you, then fire.
I like color I can see before I fire it. I never got
into china painting and stains. That is the
traditional way and more power to you if you go that
way. You would have to convince me that it is still
more economical considering lost work due to refiring
and poor results due to lack of visual feedback when
applying.
They didn't make micro-fine pre-fired ground pigments
in mass production. That is the answer to "why did
they always use stains, then?"
Also that stains can be used either in OR on glaze. I
agreee that velvets are too expensive to use to color
glaze. But that is not what you described as your
goal, spray surface application.
Good luck with it!

one more tidbit.
I said they were not economical for coloring glaze. I
meant that in reference to large quantities of glaze.
If you just need a bew tablespoons for a spot of
color, they work pretty well, but some go matt, so you
have to test for this. And I could see that being
just the thing for unusual spot color.
I use a bought glaze in the tiny jars called "candied
apple red" to glaze the area of my chops on my tiles
these days. I finally am back to work with my studio
refit of last week. I am still clearing debris, but
the first firings were really exciting. The new raku
kiln is fantastic. We built it in 2 hours and it
fired to temperature in one hour with a ward plug and
play burner and a small propane tank.
Now I have electric, chimney, pit, raku, and soon
wood/gas hybrid kilns here on my brickyard so the
world is my oyster.
woohoo.
