Dear Tracey,
Many moons ago some people used to dip their raku into used motor oil
after the reduction but while it was still hot.
Otherwise, cold treatment could be india ink.

I find the best "inhancer" is to get it into the reduction chamber
faster so the reduction does it. (Yes, I know you are asking about
afterwards...) After maturing the glaze try cooling the kiln to 1600F,
place the piece on a banding wheel protected by a IFB, spray it with
compressed air, and quickly place it into the reduction chamber.
Using compressed air will quickly cool the surface and allow the clay
body to retain some of the heat that is needed to get those dark black
crackle patterns. You will be able to see the amount of crackle pattern
that develops and determine when to reduce. Also by using the
compressed air you will not burn your face while blowing on the surface.
Afterwards, well, india ink on a hot pot or black shoe polish and put it
into the oven on low for a few minutes but...

We used to call it room temperature reduction. Try a solution of
india Ink. Start with one small bottle per gallon of water. you can
spray it on your work or soak the piece in the solution for a period
of time.
timing is everything, so you will have to test, test, test

Hi,
ry re-heating it and put it in some newspaper, use charcoal lighter to
ignite if necessary, then cover it tightly. Mike

HI,
You can also use a paste lamp black or stove black found in local
hardware stores. Mike

If I want a nice dark crackle on raku, I dunk it straight from the
kiln into used motor oil, it also gives a nice satiny feel to the
glaze.
