Glazes to Try

...via Vince Pitelka:

Killer Tomato Red
Kona F-4 48.2
Flint 25.9
Bone Ash 11.6
EPK 7.1
Magnesium Carb. 7.1
+ Red Iron Oxide 7.1%

Caramel Yellow
Neph Sye 19.0
Flint 17.9
Spodumene 17.8
Dolomite 16.9
G-200 14.3
EPK 14.3
+ Titanium Diox. 8%
Honey Luster
G-200 Feldspar 40.9
Flint 19.1
Talc 14.0
Gerstley Borate 11.5
Dolomite 7.3
Ball Clay 7.2
+ Mang. Dioxide 8%


That last one sounds like an exterior-only glaze.

Also, is it just coincidence that all of the glazes from the list that got my attention have food references in the name? I must be getting hungry!

And thanks, Vince, for publishing these; and thanks to other potters who do the same. I've always thought it completely silly when potters get all possessive about their glaze recipes; as though bodies of work might become indistinguishable if someone uses your glazes! Painters don't do that: "Oh, I've got my special blue, and no one can use my blue except me." I often find glazes online, and almost always alter them to work in my kiln, and when I do, I am more than pleased if someone else can use the recipe. either as-is or with their own alterations. In this way, we all benefit.

Not sure how these will play in the soda atmosphere...but I can think of a good way to find out!

Both the Carmel Yellow and the Honey Luster do well in both salt and soda along with another of ACC's stock glazes Somebright Green. They also fare well in a wood fired kiln. I have never tried the Red. Didn't like the look of the test tile.

I agree with Jody here, all would work in soda or salt; but the iron red might be best saved as a liner. It can get a little muddy and funny in soda - at least that's saturated irons looked in my tests.
Any glaze with around 15% whiting, dolomite, barium or a combination of any of those or with some boron or talc, will repel the soda and should work fine. The color may not be the same as in a non soda or salt atmosphere.
High clay shinos work pretty well, as does temmoku, amber celadons, many ash glazes, Shaner oribe, salt yellow, white salt (most of these are in John Britt's cone 10 glaze book). There's also a large file of soda/salt glazes and slips that I and a couple of other members put on my yahoo soda salt group. You have to be a member to access them (no charge - just a way to keep spammers out). It's not an active site; but it's more of a repository for the recipes, photos of some soda/salt kiln and members work.
