Hello Everyone.
I just ordered an assortment of Mason Stains (suitable up to ^9 and I fire
at ^6 oxy) and am wondering what to do with them. I'd like to use them more
or less as water colors and to color slips. I have the slip recipes from
the recent CM article on that subject, but am not sure of other uses. I
thought I'd mix the stains with a clear base glaze (no zinc, of course),
but beyond that, I'm afraid I'm kind of lost.
Do I paint them on greenware (leather-hard or dry?) or bisque?
If bisque, must I re-bisque before overglazing with clear? (I was told that
using them under glossy glazes may cause them to run, and my clear is a
satin.)
Do they work well over unfired glazes? If so, will they leave a dry
surface, or does that depend on what they're mixed with?
What about using them on previously fired surfaces?
Any and all information (as well as book suggestions) is welcome. Maybe I
haven't asked all the questions I should have asked--if you think of
something else I should know about these stains, I'd appreciate your input.
Thanks in advance for the help, :)

Cindy:
We (the Educational Cultural Complex of San Diego Community College
District) mix Mason Stains with white slip. I personally have used pink,
lavendar and yellow and fired them to ^10 in reduction and they maintained
their color nicely. I have been warned that the stains themselves in the
powder form should be considered carcinogenic and only used with a mask and
gloves.

I use them mixed with Gerstley Borate and water to paint designs over
a 6 white glaze. They work over the clear too but I've used the
white. I think in most cases the ratio is 1 part stain to 3 parts
gerstley borate.

Hi Cindy,
You just have to try it all and see. Mason Stains vary in their reactions.
Greens with chrome in them will be quite refractory and might be dryer over
a glaze than blues with cobalt for instance. So alot will depend on the
particular colors you have chosen and on the base glaze you are using. I
use them as an over glaze wash, adding them to my base glaze and then
watering it down til it's brushable. You might have to try a bunch of base
glazes til you find one that is good, either over or under mason stains.
Experiment til you find what works for you. And take copoius notes when you
unload your experiments. I have so many test tiles that are lacking in
_evidence_..:-( .I don't think you need to paint them on greenware. You can
wash them off bisk. Very important in MY studio....
Take Care
Jennifer
