I've been trying to start doing some painting with Mason stains but
I'm puzzled by something. You can't use the plain stain generally
because it doesn't go on smoothly or it's a bit too refractory or
some impediment or other. So I've seen various recommendations, from
putting it half and half with frit to mixing up a special stain medium.
I'm curious though as to why one wouldn't simply mix the stain into
the same clear glaze as was going to be the cover glaze for the rest
of the piece. OK so there are some possible incompatible ingredients
in the glaze, like for some stains you can't have zinc in the glaze
and some colors get killed by magnesium. But that aside, what's the
argument against just coloring the base glaze with a bunch of the stain
and going at it?
Roughly the same question comes up again for me in the other
direction. For painting with colors on top of a white glaze
(a.k.a. majolica I guess!). Could you make up a base version of the
white (leaving out the opacifier) and putting in the coloring stain?
I'd surely appreciate seeing some discussion on this question of
colorings and the implied questions about application, fit, and
compatibility, whatever...
TIA

I am by no means a glaze person, but I've done some work with Mason stains.
There is no reason why you couldn't mix up the stain with the clear glaze, but
if you want the stain to be opaque, it probably won't be, but instead give a
kind of "jeweled" effect-like cloisonne. Unless you add an opacifier to the
glaze, the color will take on the characteristics of the glaze.
Actually that sounds pretty neat. But, not the effect that you want. Also, if
the clear glaze is a moving one (runny), the edges of the colors would all blur,
if the piece was flat, and run together if the piece was not.
Linda Arbuckle could probably answer the question about adding colorant to the
white majolica base.

we use a simple terra sigelatta
then we mix the mason stains into them
the terra sigellata goes on real thin with the color
it looks great
you have to keep stiring though
the stain settles to the bottom

Hello Janet,
I'll bet you get a lot of answers to this one. Anyway, just to beat the =
rush.
I find that using the stains in a glaze will dilute the strength of the =
color.
You don't need the clay and silicas etc. I finally settled on making some
veegum water and then mixing the stain with an equal amount of 3134 or 3124
ferro frits and adding the water. I tried glycerin for flow but I think the
point to to flux the stain, strengthen the color layer, and do without as =
much
of anything else in order to keep the color strong. Yes I admit I tried the
antifreeze in the mix that Mason gives but didn't see the point. A lot of
people use gerstley, however, I found that because of gerstley's pudding =
nature,
it was harder to get an even coat or one that had the thickness that using =
the
frit mix gave.

Janet, when using oxides for overglaze decoration, I mix
oxides with my base glaze to make the overglaze.
I think you could think of stains in the same way as oxides, so,
why not?

I use the half frit and half stain in a baby food jar with a tea spoon or
so of spray starch - it makes it go on real smooth. every now and then I
well have a few white spots show up through the color stain and I don't
know what causes that. But generally speaking it works very well!!

Lynda, instead of Gerstley try Ferro 3134. Could you let me know how it =
goes??
It works for me .. The frit comes under other numbers but all the same =
Ferro
4108 and 4508..=5B leadless calcium borosilicate frit 1040-1100C =5D For =
special
effects, Raku Glazes.
Kind regards,,

Hi it's me again,
A fine young fellow who was at the time Carl Miller's glaze guru once sent
me a gallon of something called Magic Medium or something like that. When
we get together be sure to remind me and I'll give you a bit to play around
with, maybe it will be just the ticket.
