low-fire copper reds?

Jeff Lawrence on thu 2 jan 97

In an idle moment, as the memory of a deep sangdeboeuf color wafted acrocss
my consciousness, I started mulling on the possibility of getting that effct
at the temperature range I usually use -- ^04. Are there any fundamental
gotchas here ? Anybody tried and failed? succeeded? I'd love to hear about
either experience

Here's an unorganized glop of probably specious mulling:

- if the color is dependent principally on the copper cooling at the right
rate, any temperature otter do.

-- since both raku and high-fire temps give em, seems like in between ought
to work too, somehow.

said he, nose pressed hopefully against the window of thermal opportunity!

Jeff,

I can't see why not, given the right glaze and atmosphere. I
get them consistently with a raku glaze fired to about 1650 F,
and the reds are achieved in the kiln, not in post-fire reduction.

There has recently been a longish post related to that, full of
really good technical info, but I can't find it offhand -try the
archives? Or someone may remember it more clearly than I do. It
was in the past few months.
