mason stains on ^10 stoneware?

updated sat 19 jun 10

 

Cathi Newlin on tue 15 jun 10


I have a question about using mason stains to add a little color to a
cone 10 piece.
The piece is white stoneware. It has a sprigged design on it, and so at
bone dry, I brushed on a black slip and then wiped it off to enhance the
design, then I bisque fired it.
I want to add just a few pops of color to it before applying a clear
glaze to it.
I'm a tad confused about doing this. One place suggested 50/50 stain and
feldspar, others have very complicated recipes
It seems simply mixing the stain with water and brushing it on is not
the best option?
The areas I want to color are small - no more than 5 areas of less than
1/2 square inch each, on a piece that's nearly 3 feet long, so I'd like
to have some fairly strong color.

Thanks everyone!

Dear Cathi Newlin,

Since you are using a black slip my suggestion would be to mix a small
amount of fresh (White) clay that forms the basis of you black slip with
your Mason stain.

You only need enough clay to sinter the applied colour to the clay or to th=
e
black slip. Five percent by weight may be sufficient and would hardly dilut=
e
the intensity of your intended colour.

Using an excess amount of flux (Felspar or frit) with the colour may seal
the surface during bisque firing, later preventing capillary draw during
glazing. This can lead to a scared surface.

You may need to experiment before working on you larger piece.

Hey Cathi, Since you plan to use a clear glaze over all, why not just
mix a bit of the stain up in a small amount of your glaze? Depending on
your color, you can increase the strength to get the brightness and if
it isn't for functional ware, you'd have no worries. The encapsulated
stains do great at high temps. I've also had great luck with Mayco's
underglazes, Flame red and Dragon red and their Stroke & Coat Hot Tamale
staying bright at cone 10. Good luck.

Hi Cathi: You've likely considered this, but in case not... You will als=
=3D
o want to=3D20
check the reference numbers on the Mason Stain Chart. Some colors will n=
=3D
ot=3D20
hold up to cone 10.

Have fun testing.

I've used Mason Stains and other commercial stains in Tony Hansen's 5 part
glaze for cone 6 and for the most part they are similar to water colors.
Generally I use around 10% with the glaze. I can't speak about ^10 but most
stains work at cone 6, although not all. For certain colors I use more stai=
n
and for blues I use less.

At around 10% you might want to add an opacifier if you want a solid color
look without seeing brush strokes.

I particularly like the Spectrum Stains (sold by Bailey Pottery at:
http://www.baileypottery.com/glazes/spectrum2000.htm
and I'm sure sold elsewhere as well) because they come in plastic jars,
making them accessible to measure and easy to store.

I've bought the encapsulated reds and oranges at US Pigment because their
prices are excellent. I believe that theirs are made in China, although I
don't know where other manufacturers make theirs. Check out:
