Can someone recommend a white glaze recipe that is sure to craze at zone 6.
I have been unsuccessful in my attempts using different high expansion
recipes on standard clay bodies. I even tried one given in Mastering Cone 6
Glazes that is guaranteed to craze on common bodies. I got a rather nice
satin finish but not one crack.
Thanx

Hi,
Got this recipe below from clayart but have not tested yet!
Please let me know if you do try it.
Thanks,
Heloisa
Cone 5-6 Crackle Glaze
Neph Sy ........................70
Whiting..........................20
6 Tile (Georgia Kaolin) .... 50
Total..............................100
Simple, eh?
Size of crackle varies w/ type of clay body used. I have used it on
porcelain at cone 6 and found it to be a small crackle, and semi-gloss.
Also, looking at the glaze contents, it seems this would take stains very
well. Crackle glazes should not be considered food safe....decorative only.
I have only used it in oxidation, and I do not know what it will look like
in reduction (I imagine it will still be a crackle glaze). I have not used
it over underglazes, but I don't see why not (it's not opacified). You can
rub black india ink (or some other color ink, or paint wash, or stain and
refire...whatever, into the craze lines I suppose). It will continue to
crackle (craze) for a couple days, but does have crackle immediately after
unloading. Not a raku glaze.

Lana Wilson has this on p. 45 of her book "Ceramics: Shape and Surface". It
is called John Atherton Crackle: Add 30% soda feldspar to dry WC510 White
Chun from Laguna Clay Company. I have not tried it but plan to.
By the way, this is one awesome book.
