Hi Ron,
No problem, I competely understand, here is the recipe.
Leach 1234
Custer Feldspar 40
Silica 30
Whiting 20
Kaolin 10
----------------------
Zircopax 10

"I'm a student at Henderson State University working with some fairly =3D
stable glazes in the college's studio (stable as in, not much crawling), =
=3D
and Leach 1234 is one of them. It is our standard "white" glaze. It's a =3D
great glaze, except it tends to make glaze-less bubbles along the rim. I =
=3D
hesitate to call it crawling, since it's minor, but it's not at all =3D
pleasing.
At first, it was thought to be a problem with user error, when it came =3D
to applying the glaze,,, but that isn't the case, as tests have shown, =3D
so.... All I can think of is the recipe.
My professor thinks it might be an issue with the silica content so he =3D
wants me to experiment with the quantity in the glaze. I plan to do =3D
that, but I figured I would look into other solutions. Anyone have a =3D
clue what could be causing this?" =3D

Hi Andy,
I need the exact recipe for that glaze with the kind of spar and clay
- then I can suggest fixes.
What kind of clay are you using? If there are solubles they will come
up to the rims during drying and the clay there will get over fired in
the glaze firing - try drying the wet pots upside down and see if that
makes a diff.
How are you measuring firing temperature?
