Hi all-
I am working on a tile project and want to get a brilliant screaming
red, so it's time to jump into something I haven't yet explored-
inclusion stains or commercial red glazes. There are so many slightly
different reds out there and I can't guess from my computer monitor
which one will give me what I want. I want to get as close to a
certain reduction copper red as possible. No purple at all, maybe
slightly orange. Any suggestions? I'm guessing... Mason 6033 Sunset?
DeGussa Intense Red? Laguna Dynasty Red glaze? Do any of these give a
translucent effect or are they all pretty much opaque?
If I'm using a stain I plan to use the 5x20 ^6 base as it seems that's
what is recommended in the archives.
I LOVE glazing!

hi, Ivy.
the good news: i've found the color chips from mason to be pretty good
indicators. of course, the paper chart is more reliable than the
variability between computer monitors ;-(
and the mason inclusion stains aren't picky... they don't care about the
amount of calcium or zinc in the base glaze.
on the other hand, the red inclusion stains from mason all contain
cadmium. and i'm pretty easily spooked by that. i know, encapsulation
is supposed to make it safe. but i'm just not smart enough to feel
comfy with it... when it's wet, when it creates dust, etc.
i suppose that if i REALLY wanted to use it, i would get a cup tested,
just to be safe. just to be sure that my glaze was mature & stable
enough to carry it. but maybe i'm just being overly-cautious.
i'd love to hear from folks on-list who are chemistry-savy about cadmium
inclusion stains.

Hello Ivy:
I use stains a lot , I had no success with red until Degussa came up with
the inclusion stains: their Intense red is really that. but I love their
bourdeaux ( sp?)red, it is a deep red but might not serve you because you
specifically didn't want any purple hints.
Then came Mason inclusion stains and they have a very nice red with some
yellow in it :Lobster which I like and use a lot.
I actually order by the 1/4 Lb. either Standards or baily and possibly
anyone that sells Mason stains. I have not tried teir sunset but love
their tangerine for an orange color.
I use a different clear glaze and they work fine with it. I personally had
no luck with the 20X5 but I even tried them with commercial glazes with
good results.
Disclaimer: I brush the stain on first and then dip in clear glaze, never
mixed the stain right into the glaze.
Enjoy your Red Journey

Hi Ivy
Mayssan had no luck with 20 x 5 and I do. Just illustrates that we need to
test glaze in our kilns with our materials. However, I also use a
commercial clear base for some of my "pigment" glazes, as I call them.
Keep in mind that the clarity of color will depend on your clay body color,
the base you chose and the precent of stain you use. I use 12% which in
most cases gives you maximum intensity.
Good luck,
