Do you know about lustres?
You can find it on the
work of Old Noritake
shining as metallic
iridescent colours.
Lustres are made from
metallic oxides and
are supplied in liquid
form and are usually
almost brown and green
when applied straight
from the bottle. Based
on metal compounds dissolved
in organic solvents
their true colors are
only achieved or recognized
through firing. On smooth
glazed surface they
produce colors of high
brilliance with metallic
iridescent colors.
Lustres may be applied
onto any fired glazed
ceramic including Porcelain,
Bone china, Tile, Soft
glazed ceramic.
After firing, lustres
form a very thin layer
on the surface of glaze
but as they're susceptible
to abrasion from use
of rough substances.
Generally they are used
as@decorative pieces
only. Lustres are not
completely permanent.

Cleanliness and clean
firing are the most
important things during
lustre work.
When working with lustres,
you are literally working
with chemistry set.
If your brush is dirty,
and is still moist from
another medium, lustre
or paint, you will get
contamination and the
results will be muddy.
Be careful!! Putting
bottle caps back on
wrong bottles, or not
washing your brush or
not having separate
brushes for separate
colors, carelessness
will result to disappointments.
