Hello,
=20
I am looking for a good slip recipe using oxide additions rather than stain=
s. I work in an art department at a colllege we have lots of oxides and no =
stains to make a yellow slip in particular. We also need to keep costs down=
so buying in stains is not an option.
=20
Any help would be greatly appreciated!

Dear Judd Cullen,
Why not dig into "A Potter's Handbook", 3rd Ed , p 319 by Glen. C. =
Nelson. Though you might not get any recipe that would be directly =
useful you will be appraised of ways of making your own stains.
Best regards,
Ivor Lewis.

You didn't say how high you fire, what atmosphere,etc.
I use titanium dioxide for yellow slip at cone 10 in my soda kiln.
You might try a typical slip recipe for whatever cone you're working with,
with 7-8% titanium dioxide.
In reduction I can get a warm mustard yellow on a white stoneware or
porcelain and a more muddied yellow on a higher iron bearing stoneware.
If you go the gallery page on my web site, there's a bird topped pot that
shows this slip.
Regards,
June

Weyl says vanadium with tin is cream yellow and that praseodymium
is yellow. You may have to hunt to find a supply of them though.

Sorry. Electric kiln, standard stoneware, (1260) and earthenware (1140). It=

I did think about titanium dioxide, and have so far been testing vanadium p=
entoxide and tin oxide, and yellow iron oxide line blends. Waiting on resul=

I will give it a go. Thanks for your help

I use 10% Rutile to get a nice, warm, fairly bright mustard yellow at ^6
electric with no glaze over it. The slip I use is the ^6 version of
Bringle's Wet Dry Bisque Slip, which can be found in the archives. It is
quite vitreous, and might more accurately be called an engobe, which I'm
sure adds to the vividness of the color without glaze over it. I have not
tried it with glaze over it. This would probably work in other slip
recipes, too, but the unglazed color might be duller if less vitreous.

Using Rhodes Glaze #21 Cone 6 Base Glaze
Measure 1/2 tbsp of it and add to this: 2 full (1/8's tsp) of Praseodymium
+ 3/4's of an 1/8th tsp of Zircopax + a dab (just enough to cover tip of
1/8 tsp) of Iron Ochre.
This will give you the same yellow as the Amaco Celebration HF 161 Bright
Yellow -- Used both on a cup yesterday -- viewed this morning and they are
nearly identical. Boy! Was i pleased !!!

Vanadium has some serious toxicology - know the materials you are using so
you can take whatever steps you need to avoid problems.
Not much is know about praseodymium except it is a blood thiner.
