Elaine Coleman uses a mason stain in her Celadons to achieve the blues and greens she gets. It's possible someone may have used any number of mason stains to get the color you had if they didn't use the recipe CC has below.

That being said, I've had great luck using the recipe here with a mason stain, so if you don't get results you like from CC's recipe feel free to try this one. The green mason stains do not burn out at all at cone 10R, I haven't tried blue yet, but judging from her pots, I'm sure it'll work out nicely.

Here's the recipe I use from an old Ceramics Monthly issue:

Elaine's Celadon Base Glaze

(Cone 8–11, reduction)
Whiting ....................................... 21.24%
Zinc Oxide .................................... 2.74
Custer Feldspar ............................ 24.87
Frit 3110 (Ferro) ........................... 8.76
EPK (Edgar Plastic Kaolin) .............. 17.52
Silica (200-mesh Flint) ................... 24.87
100.00%
For white, add 0.71% tin oxide; for green,
add 0.88% Mason stain 6201; and for iron
blue, add 1.59% Mason stain 6391. Yields a
smooth transparent glaze that is great over
carved or incised decoration on porcelain.

I hope this helps!

My Celadon pots in this set use this recipe, though I used a different # green mason stain than she does:

Good Luck!

James & Sherron: I think the Einstein quote is very succinct, and very
well outlines the challenges we face in our current endeavors. I think
it is a moral dilemma which we should keep foremost in our minds. It
is also worth remembering that material existence is only a perception
we entertain and limiting ourselves to materialistic solutions will
always most certainly fail.

As Rumi says --
"There is another world inside this one --
no words can describe it.
There is a living, but no fear of death;
There is Spring, but never a turn to Autumn.
There are legends and stories
coming from the walls and ceilings.
Even the rocks and trees recite poetry."

This is partly why some people will pay $10 for a $1 item at Whole
Foods store because they believe that they some how participate in
this alternative world. They might be correct in many ways. It is hard
to understand why creative people will sometimes spend all they have
to secure their world - it is like the parable of the parable of great
price; sell all, buy the field. Economic "realities" are driven almost
entirely by emotions and perceptions -- and those who are richer in
this realm are richer indeed.

I have a book by Tom Coleman called Glazes I use. It has a section
of celadon glazes, but none is called a blue grreen. Actually looking
at it again I found one with a variation called blue/green. It is
Elaine's Celadon Base:

F-4 Soda Feldspar 43.67
Barium Carb 13.63
Whiting 4.51
Silica 31.12
EPK 2.79
Tin Ox 1.09
Zinc Ox 0.54
Fireplace ash 2.15
Ferro Frit 0.54
____
100.00

For Blue Green add:

Yellow Iron Oxide 1.6%
Chrome Ox 0.1%
Cobalt Carbonate 0,054%

He writes: This is a very clear celadon base. The best for carving.
It has a smooth and shiny surface but does not tend to shift if
overfired.. Works best on porcelain. Cone 8-10 reduction.

I hope this helps. I will add a disclaimer that I have not
personally used this formula, but his receipes from this book are
generally reliable.

C.C. Happy potting.

The way I learned it if there is any colorant other than iron in it then it
is no longer a celadon. But then I was trained as a potter not a painter.
Blue celadons have come from glazes with low iron content (Less than 1/2%
and little or no taitanum in the glaze) It also helps if the glaze does not
re-oxidize on the surface during cooling. (Most early Chinese celadons were
fired in saggars which may hinder the re-oxidation of the glaze. (Oxidized
iron is yellow the underlying celadon is blue : Yellow + blue = Green).

Your Celadon may vary,

Like I said there are six more Celadons in Coleman's book.
My own preference is for Blue celadons but that takes a really clean
porcelain and G-200 spar at the least. Craig Martell does blues really well.
