From Roger:
"Probably best to avoid a matte like this (Ca, Mg, Sr, and Ba) with nepheline syenite as the alkali metal source."


I decided to try it anyway - I like the barium/strontium - i hope it will brighten the colors.

RESULTS:

Pink at 8,4,2,1%

At 8% the glaze is textured and ultra-matte with a rough texture.

And a bit of Neodymium to 4% Pink made it a bluish-pink.

Here is 4% on black mountain and granite

*The Praeseodymium seems to need a bit more water - it was very thick at 8%

It seems that the higher percentage stains came out more eggshell then matte.

At 8%, 4%, 4% with a unmeasured (tiny bit) of peacock added, 2 and 1%

At 1% the color is not noticeable

RESULTS:

I like the this glaze a lot.  It has a great feel, like marble.  It seems to get a bit shinier with the higher percentages of stain.   I really like the base color, without any stain added.  I will test this base with a few different clay bodies.

Here are some samples with various mason stains, fired at cone 10 reduction.
