Logan, this is a bit like asking what's the right amount of cream to
add to your coffee- it depends on how you like it. I don't know what
you mean by "some color". But a general rule of thumb with most
stain colors is that 0.5% will make a noticeable pastel color, 2-3%
will be a fairly strong color, and anything over about 8-9% will not
make any deeper a color.
As an example, I use 5-6% of a black stain (Mason's chrome-free
black) to make a lovely blue-grey. If I wanted to use it to make
black, I'd probably have to use at least 8%, maybe 10. So what's the
right amount of this stain to add? Depends on whether you want grey
or black.

Not sure about quantity, but remember to add a bit of
gerstley, or some other fluxing agent, as stains can
be quite drying. I add then to lowfire glazes, and
then fire to cone ten in soda, and still have to throw
in something, or it's too dry. Good luck! Jules

I will give you these basics....
If you are using black, make sure it is a cobalt free black, otherwise you
won't get black at all.
There is no "right amount". There is only the amount you need to get the
color you want. Also remember that you can mix stains like you can paint, in
order to get the shade you want.
I use 1 crawling base and 1 glossy. That said, variable like clay body,
bisque schedule, and your basic ingredients all will vary. I have altered
both my base glazes ever so slightly with each stain. This is because stain
is a frit, and will change the chemistry of the base. Some flux more than
others.
Another variable would be if you are using an engobe between your clay body
and your glaze (like I do). This changes the result even more.
Sorry I can't be more specific, but like all glaze testing, your mileage may
vary. TEST TEST TEST.

I use stains in a glaze base on a rare occassion.
5-7% is what I generally use. With the stains that I use, going over 7% is just a waste of
stain.
Good luck.

Conventional wisdom says this is true...but the mag carb in a crawling
glaze soaks up color like a sponge. It is not unusual to need 15% or
more. That also means you need to adjust your base as you adjust your
stain percentage.

I used Mason stains when I fired to cone 5 oxidation. I have just started
to use them again for overglaze painting at cone 11 reduction.
Some experimentation is required. I mix the colorants by eye, into the base
glaze, a white matt. Try a very small amount, like 1 oz of glaze. Add
stain in 1/4 teaspoon amounts. I add enough to give me the amount of color I
want to see on the finished piece. You can thin it with water, or add
glaze or colorant until you are happy with the results.
This is really a trial and error process, and won't be to everyone's liking,
but I like it that they are not always exactly the same, even on the same
piece. I paint directly on the surface. There is even a good red for my
flowers. If you have ever mixed oil paints this is somewhat the same. What
it can so is give more dimension to colors.
Best to all,
Rikki Gill
