? on theory of refiring iron reds to ^06

Yes, Carol, it does often help to soak and/or slow-cool iron reds, as it
gives time for the development of the crystals that give you the red
color. Whether it will work with your particular glaze, you will have to
find out by experimentation. I would guess that you wouldn't need to soak
for as long as four hours, though -- try an hour or two, for a start,
between 700 and 900 C.
