Stephanie,

You ask:
>
>1) Can aventurine glazes like this be done in reduction?

I have not every achieved it.



>
>2) If I used your Goldstone glaze in reduction, would the high iron
>content turn the glaze color black?

Yes, the high iron makes it turn a beautiful green, black, brown and
yellowish colors. But use a drip tray as it will run and ruin the shelves
of the kiln.


>3) Is there a colorant that you know of that would give that beautiful,
>deep coppery color (with or without crystals) in reduction?

You would have to experiment but you could use copper ---as in luster
firing, but you would have to change your firing cycle to include a heavy
reduction soak or striking.


The best thing is to try it! Try lots of stuff. Everything on earth has
not yet been discovered. It is waiting out there for you.

I don't know all the answers nor does anyone on this list. You should just
see what they will allow at your center (respect their wishes) and then
try things in that set of limits.

I have found that, if you are not a wild cowboy and you use common sense
and drip trays, you can often fire tests in community kilns with great
success. You can also use saggars to create cone variations as well as
atmospheric varitions.

It will also inspire the regulars who are board with the routine glazes.

Get a group together and pay for a different firing cycle! Have everyone
do their own research and then fill it with tests and try something new!
Reduction is not the only way! There are many firing cycles that can give
outstanding results, even with the house glaze palette.

Hope that helps,
