Dear Alisa:
Try the Amoco Reward Velvet Underglazes. They are supposed to be very
stable in high fire including the reds. The line is extensive so I am sure
you can find a match. I know there is a maroon that is close to what you are
looking for. My best advice though is whenever you need an exact color
especially when you are pressed for time is go to commercial products. Good
luck let me know how you make out.

Dear Clayart,
I need to paint a monogram in a Bordeaux like color.
I do not have a lot of time left to make tests.
I tried some under glazes, but they fired to a pale lilac, becoming
fugitive at cone 6.
I thought about Rosenrot Red Glaze or Big Red from Will.
But I will put a 20x5 white over it and am concerned it will run or bleed out.
I was thinking maybe Manganese Diox. (although I avoid it) as an oxide wash.
It would not matter if it was darker, almost brown, but just that it has a
purplish cast.
I read that Manganese can go purple (usually unwanted), but in this case, I
want it.
If I mixed Manganese with my usual Rutile and Ball Clay wash, do you think
I have a
chance of achieving a purplish brown?
I fire cone 6, ox. and my clay body is white.
Any suggestions most appreciated as I am firing in the next couple of days.
Best regards,
Alisa in Denmark

Alisa,
Try the bordeaux red stain from Cerdec/Degussa. 5% in a glaze will do
it. Mia in ABQ

I have used a mason stain called Blackberry wine that fires a deep burgundy
when painted or airbrushed over a white satin matt or zinc-free clear and
fired ^6-8 oxidation. You may need a good heavy coat, first just mix about
1 heaping teaspoon with about 2 c. water, sieve for paasche airbrush, or
paint on. (I am never very exacting when mixing this, as it really doesn't
call for precision!) You just have be careful painting over a glaze as far
as the mongram painted application not appearing streaky looking.
Hope this helps. Best of luck

Actually, the regular Amaco underglazes
are more stable at ^6 than the Reward
Velvet products, in my experience.

Do Mason stains publish a list of ingredients?
Or do you just have to accept them with no idea of the chemical analysis?
How can you then use them on food ware if you do not know what is in them?
How can you put them in the same kiln load as your other ware, and be sure
of no interreactions?
Burgundy, Blackberry and Bordeaux sound wonderful, but ...
Why are our suppliers so secretive?
There is a way around that secrecy.
Just send samples to Alfred or in the UK to CERAM at Stoke on Trent and have
them analysed. Costs, yes. But then we have the oxide formula and can, if it
is worthwhile, make up our own staining ingredients.
Probably is not worthwhile, economically for us to make our own, because the
factory sources are fritted, but at least we will know what is in there and
the reactions possible with our other glaze constituents or possible
leaching when in use.
I intend to take a batch of stains from our local supplier to CERAM in
December, when I visit relatives up there. The analyses can then be put on
my web site for all to see.
Or should I charge you all to recoup some of my expenses?

Alisa, Cerdec Degussa stains has red, yellow, orange and probably
bordeaux stains which are supposed to be stable to cone 9 or 10. Why
not look into that?

Hi Snail, and Alisa,
I use Amaco Velvets, and have quite a lot of the colors, all which
I tested at cone 6. Only a couple of the very light colors changed
significantly at cone 6. Many of the colors darkened a bit, and a
few became slightly glossy. The nice thing about them is that they
are pretty true to color in the unfired state, and you mix them like
paint to make your own colors. Of course, Alisa, you may not be
able to get them easily, or in time for your piece, but I will send you
some if you'd like. Write me off list.
