Default Low-fire lead-free glazes?

Hi. I was looking at Charles Gillespie's Cone04 - Low Fire Pottery Book (2nd
ed.), and noticed that most of the glaze recipes contain "white lead." Does
anyone know of a source of low-fire LEAD-FREE glaze recipes? Or in the
alternative, does anyone have any low-fire lead-free recipes that they would
be willing to share? Thanks.



Whatever you end up with will most likely use boron
in some form or another. Here's one that I've used,
from Glaze Projects by Richard Behrens (p40).

Cone 04 Base Glaze - Glossy
Gestley Borate 60 (I used Gillespie Borate)
Kaolin 15 (EPK)
Flint 25

Behrens shows this same basic 3-component glaze
in different proportions for cones 08, 04, 1, and 4.
