The point of my post was the copper luster made a stoneware pot have a flash
of bright copper luster and I never tried to do that before....re-fire to a
lower temperature in an electric kiln ....stuff it with combustion till it
turns dark...and pull out Raku effects on a totally table safe piece of
pottery.
I am not aware of that as a popularly used technique ....have I missed too
many issues of Ceramics Monthly?

In a Raku class a student raku glazed and fired several previously mid-range
fired glazed mugs and got some nice looking copper flashes and raku effects
for the effort. At the time, I wondered if they were still table safe. I
was surprised that the re-firing didn't crack or otherwise structurally
affect the pieces. Your description, and observation of the result in the
class, would seem to indicate that this is a viable process. For me, I am
hesitant to reduce in my electric kiln, having read the Clayart debates over
time, for fear of taking life out of the elements. The in class example was
in a gas fired fiber kiln. Interesting post.
