Below is a query from a friend who is having trouble with the low fire =3D
clear glaze she is using currently.
She wants to avoid the problem with the brushed on glaze.
I saw one of her pieces and where it overlapped gets cloudy.
I suggested she dip or spray the clear to get a more even coating. =3D20
So she is looking for one that is sold dry weight.
You can respond to me and I'll pass the info on to her.
Thanks,

Actually it didn't occur to me that you weren't vitrifying your earthenware=

Curious minds want to know..." Have used Karen's as base--adjusted to the
higher temps at which I work."
What temp is that and how have you adjusted the glaze?
