Ivor: I honestly do not think any glaze can be new unless there is a =3D
newly available material in it, or there is a newly available firing =3D
technique.
I think Steve is right: the basic Leach Limestone started somewhere =3D
else.
As there are so many variables--kind of kiln, kiln atmosphere, fineness =3D
of grind of materials, purity of materials, clay body, heating and =3D
cooling speed--each potter develops something perfect for her =3D
circumstances. =3D20
I love high magnesium glazes. I have a stash of recipes. Once I tested =
=3D
like a dozen and it was almost impossible to tell them apart--except for =
=3D
this one having a slightly higher or lower maturity,
For instance: The availability of frits on the market made it possible =3D
for all of us to use formerly soluble materials., BUT they had been =3D
used in soluble form, or "fritted at home" before. When I was at SAC we =
=3D
did not use strontium --it was there,but so pricey and hard to find we =3D
just toyed with it...did not really use. =3D20
Now the computerized electric kilns will introduce "new" glazes..which =3D
will be made out of the same traditional materials fired differently.
My admiration and respect for Otto Natzler is boundless. But I know in =3D
my heart that his yellow glaze is a combination of known materials, and =3D
a discoverable firing program.
We move about in theoretically predictable circles.
