a simple definition for those that do not
know what it is:
a white, variegated, ash glaze.
it has a history in japanese wood fired glazes.
there are dozens of variations of this basic white glaze.
we use one that zac loves for basic ware, from mark hewitt
in our wood firings.
if you have a cone 6 electric pottery.
make a white glaze and add 1 percent rutile. + or -
fire it to cone 7.
you get the idea.
it is not a mystery glaze.
mel
it is sort of the opposite of temmoku.
(hundreds of variations.)

Actually, unlike most white glazes, the color does not come from metal
oxides, but form a saturation of silica. It is a glaze that gives
folks like RR hiccups. ;^) I would suggest trying to incease the
frit in the synthetic glaze to get a cone 6. Do a lineblend. The
original is fired to cone 8
I've used Leach White over Tenmoku, but it is stiffer and while it
has some movement like Nuka, it is nowhere as nice. See for yourself
below.
You can see it applied over tenmoku here:

Any silica saturated white will have similar qualities. It is unique
in the unusual way it gets its color. Chun is another example of a
glaze that gets its color in a non-typical way.
Folks asked in private email for the tenmoku recipe in the glaze
pictured above. Here is one below:
Temmoku cone 9-10
Whiting 17
Custer 33
EPK 10
Flint 40
R.Iron Ox 11

On this pot:
http://images21.fotki.com/v760/photos/1/199764/814063/AUT_0020-vi.jpg
It is pretty low in iron and high in alumina. It is old style
shigaraki clay with feldspar stones in it.
