Dear All,
I wrote to the list in February to ask for input on why the Guan Ice Crackl=
e
from John Britt's excellent book tended to turn smokey in my teacher's kiln=
.
Several people kindly wrote back with suggestions on how to fire and/ or
change the recipe.
Turns out finally that it was merely a question of monitoring the specific
gravity (difficult, since water evaporates quickly from the bucket in this
hot climate and kind-meaning students add water as they see fit). If the sp
gr is kept to 155-160, as stipulated in Brit's recipe, it will stay nice an=
d
white, with only a bit of yellow smoke curling around the edges (kind of a
nice touch, I think).
There's a longer explanation of our Guan troubles, incl. pictures at

Thanks to everyone who responded ;-)
