Hi Joyce,
My favourite is Pinnell's copper over an 8% rutile blue glaze on
a tessha or kaki base glaze.
Just doing six plates for youngest daughter with this decoration.
How are you by the way? ----Best Wishes Maggie----

Good evening Joyce,
The studio mate I mentioned uses the red/blue reduction copper glaze stamped
decoratively over several of his other glazes - most effectively (I think)
on a tenmoku, but also on a celadon on stoneware which has been loosely
brushed with an off-white slip. He burns designs into cut sponge segments
to make his stamps. Over the tenmoku, for example, he'll stamp one pattern
in red(blue) into the interior of a flanged bowl or platter, then stamp with
a slightly different pattern in a gold colored rutile glaze on the flange.
Somtimes intersperses dots of a third color. Overall effect suggests
African, or certain Asian, paterned textiles, without looking literally so.
I don't know any specifics about the particular reduction red glaze he uses,
nor the amount of cobalt he adds as a back-up colorant.
Good luck with your experiments.
Too tired to add another word. Back-to-back glaze firings getting orders
finished and gearing up for this year's 5(!!!)-weekend Berkeley Open
Studios.
