"Comment about slow cooling one fired piece and refiring with added glazes.  You will not get the same results because when you layer glazes in a one fired piece you can get more of a mixing of glazes due to absorbtion of one glaze on top of the…"

"Refiring a glaze at Cone 04 which has been previously fired to Cone 5/6 is merely another way to add a slow-cool and create devitrication and crystallization. A slow-cool takes place between 1,800 F anf 1,500 F. A bisque firing to 1,888 F brings…"

I using this similar look on a piece of bisque right now.

Bailey Shino layered over Clear with 15% Zircopax. So the brown is not the break, but the top layer of glaze.

White Bird glaze in Insight-Live database

Randy - Lakeside Pottery uses each new glaze for three years at their studio only, after which they publish the recipe for others to us.  I've found them helpful.

Lakeside Pottery - Antique White

Antique White cone 6 glaze with brown breaks

Marina Reijsmeijer and myself are listed as "owners", more properly "curators", of hundreds of glazes merely because we spent a lot of hours over several weeks correcting spelling errors in glazes uploaded from the Sankey Datatbase and other sources.  But Antique White is not currently in the Insight-Live database.

White Bird is in the Insight-Live database is likely the closest match to Antique White.

I've revised it with an extra 10% Ferro Frit 3269 to use with our slow-cooling schedule

Hi Randy.  I am trying to order the Special Red from uS Pigment but there is nothing there with that particular name.  I asked for it by this name and they put in Fe203-HP.  I have tried Spanish RIO, synthetic and regular RIO.  When I first started using your recipe I got a beautiful red - now it is muddy brown as others have noted.  I read something about Texas talc making the glaze brown...  Thanks for your input.

I use the recipe from the Richard Busch article "A Wood Fired Look" that is reproduced online at Ceramic Arts Daily.

Nutmeg Glaze


Cone 6


Dolomite 23.3 %

Spodumene 23.3

Ferro Frit 3134 6.8

Kentucky OM 4 Ball Clay . 23.3

Silica 23.3

100.0 %

Add: Red Iron Oxide . 1.1 %

Yellow Ocher 3.2 %

Tin Oxide 4.8 %

Bentonite . 2.0 %

I love the way it works for me as a base glaze, and it's OK as a semi-matte liner.  I just mixed up an 8000 gram batch, so I will be using it for a while. 

What is it about my pots, that makes you say I should be using something different?
