i had the pleasure of visiting the denver art museum last week. on display
in the chinese art area were some of those lovely little centuries-old
celadon porcelains which most of you have seen. aside from the obvious
challenge of matching the richness of the glaze itself, i have always
wondered how the potters got the reddish brown rims on the pots. the color
complements the celadon blue very well. does anyone know? is that rim part
of the firing, or is it added later by some other process?
also, i was surprised to see a what i believe is an 'imperial yellow' bowl
described on the label as 'porcelain with yellow enamel'. i had thought that
this yellow was maybe a high-fire oxidation glaze, not enamel. can someone
explain something about the yellow as well?
thanks, brian

I think you might be talking about an actual metal rim that was added
later. They sometimes fired this stuff rim to rim so the rim was bare
and added the metal later.
If you are not talking about an added rim, then another thing that fits
your description (sort of) is that when the glaze is very thin you can
get a reddish brown from the interaction of the glaze and clay and this
could happen on the rim where the glaze "breaks"

Brian,
The rims are unglazed so that two bowls could be stacked on each other.
Yellow enamel is different from a yellow glaze. Mia in ABQ
