freebee glazes with cullet

Hey Mark,
I have done a 15-tile tri-axial blend of glass cullet, wood ash, and
local clay. I call it my "freebee glaze series", since all the materials
are free (I make my own cullet from bottles and jars).
Anyway, I can make any glaze I want with just these three ingredients,
from dry matts, to satin matts, to celadons, to runny extra-glossies.
Of course all 3 ingredients are specific to location, so your results
may be similar, but different.
If I remember correctly, the 3 corners of the blend use 70% of
one material and 15% each of the other two. The proportions
are varied by about 10% for each intermediary tile, so over the
course of 15 tiles there are lots of variations.

If you remember form our class at the Appalachian Center, I
also use glass cullet in several of my slip-glaze recipes. I call it
"poor man's frit", since it is basically a high sodium, very low
alumina, and silica frit.
