Dear Readers:
Does anyone know of a reliable and good yellow/either matt or glass
that I could fire to cone 9-10 in reduction firing. I am seeking a very
yellow/like the crayon yellow/like a bright cadmium yellow. Can anyone help
with this one, particulars/toxicity etc? purhaps this color only exists at
the lower cone levels. If so I would appreciate hearing from you. I would
be willing to switch to a lower cone too if I knew I would have results
with this particular color. May have to get seriously envolved with
Majolica -something I've wanted to do anyway.
Thank you

Trinity Ceramic Supply in the Dallas Fort Worth area distributes/sales Cerdic
stains, the yellow one is very bright and will give you a nice yellow at cone
ten. You may have to experiment with the base glaze. The chemical that makes
the yellow is an inclusion in a zirconium crystal as I understan it. they
could give you the data on the stain though. Earl Brunner

Woo Yellow is satin crayon yellow. Warm yellow, not cold. Do you have the
formula?

LLewellyn:
Try this one. I was given it by a friend years ago. It works well on a
brown stoneware body but will shiver on a fine white or porcelain body.
Fires to ^10 - ^11 in reduction. I do a 1/2 hour oxidations firing at
the end of the cycle.
Bev's Yellow
Spar G/200 or Custer [I prefer the former]: 50
Whiting 40
Talc 14
Bone Ash 16
Flint 10
EPK 50
Total 180
2% Bentonite 3.6
5% Rutile 9
1% Red Iron [For Yellow] 1.8
or
5% Red Iron [For Orange-Brown] 9
Hope this works for you.

You might try the Spectrum Cone 10 Yellow, #1254. I've seen a chip of
this at Cone 10 ox. and it is a beautiful "sun" yellow. I'm not sure
what it will do in reduction, but it might be worth a try. Also, if you
have a good cone 10 white glaze, you could try adding mason stain 6450,
praseodymium yellow to it and see if that works.
Good luck!

Llewelyn - you can get crayon yellow all day long at C/9-10
with CERDEC INCLUSION PIGMENTS - yellow. Refer to my article in
the Mar/April '96 CLAY TIMES. Order the 6 repeat SIX digit number
#239416. (Some suppliers offer a 5 digit version which will work
but not as well & it saves you no $ so find the 6 digit versin.)
In OX you will get crayon yellow - depending on the base of course.
In REDTN. it will soften & grey slightly but still be a lot better
than an Fe redtn yellow (Woo yellow etc.)As for safety, I have had
5 or so bases professionally tested and consider them safe.
Find a base YOU like, develop the color & have it tested.
If no supplier near youu carried the pigments, cntact Marin
Ceramic Supply in Richmond CA. Good luck. Karen Gringhuis
