Oribe greens are great wood or salt fires, full of surprises
as you note. They have a LOT of copper in them, though, so
I wouldn't serve my sliced tomatoes on that platter, or mix
lemonade in the jug. Not that I think folks would fall
writhing on the ground - they wouldn't. But the copper will
leach with acids, so you should use it judiciously.
The reds/mauves are just where the glaze is trying to make
(IS making, in fact) some copper red. The famous "shinsha"
glazes that Mel speaks of. It's been in use a long many years.
You might choose to use a liner glaze inside tall forms, if
you wanted them for table use, and the Oribe on the outside.
You likely will note that the "mauve" you speak of is mostly
on iron-bearing bodies. The brown of the clay is muting
the pink/red of the nearly transparent glaze. Tends toward
brighter pinks/reds on white or porcelain bodies.
