Dear Clayarters:
What is the best way to achieve color development during Raku reduction?
Most of my pieces wind up an uninteresting uniformly bronze luster. Any
suggestions?

try spraying copper carb over the glaze and then firing. Mike

I think the solid copper effect you're getting is from over-reduction. Try
letting the flames really get going in your reduction barrel before putting
the lid on, and don't use a huge amount of reduction material. You may also
try firing to a slightly lower temperature; we find that if we fire quite
high, there is a bigger chance of pure copper and not a lot of good color.
But, then again, everyone has their own personal way of successful
rakuing---what works for one person may not work at all for another. Good
luck!

Linda;
You are forcing darkness in your color by over reducing your kiln, this
results in loss
of brightness in colors. Oxy firings give bright and reduction give dark.
Try just a slight reduction at very end by stalling or closing down for
2-3 mins, or
the chimmeny(manifold) and see if you get improved results.
I'm presently getting brighter surfaces by using a slip made from "Big
White" over
Soldate60 and the crakle and color reflectiveness is amazing.
