Luster colors are applied to a fired glaze surface. They create
iridescent "overtints" of color with various degrees of
translucency. The darkest colors become quote opaque with an almost
"metallic" surface. Apply over a clear or white glaze to
achieve a specific luster color, or experiment over colored glazes for
exciting new color variations.
The underlying glaze surface must be clean and dry. Clean with
Hanovia Dispersing Agent or alcohol. Allow alcohol to dry
completely. Use a clean, dry, high quality, soft bristled brush.
Apply evenly, except where specified otherwise.
Ventilation is the key to producing vivid overglaze colors. In
addition to vents, it is often best to keep kiln lids and spy holes
open. Experiment to achieve the best firing schedule for the results you
desire. Here is sample firing schedule: Set kiln on low for 45
minutes. Turn to medium for 45 minutes. Turn to high, close lid,
wait until witness cones mature. Turn kiln off, close up holes until
kiln cools completely.
Only clean brushes with brush cleaner. Alcohol contains water
and the inner brushes will not dry completely.
When firing both metallic and lustre colors on the same piece, fire them
one at at time: metallic first then lustres.

Liquid Bright Gold "N": Contains 11% Gold,
the highest in the industry. Rated 23+ karats for the truest, brightest,
most reflective gold finish. Fires from Cone 019-017.
Glass Gold: Contains 10% Gold, formulated for
glassware. Fires at Cone 022.
Halo Metallics and Lusters: These are dilute
concentrations of metals in a solvent system. They produce varying
patterns of metallic circles or "halos" over the glaze
surface. Apply 3 coats to a clean, dry glaze surface, allowing 1 minute
drying time between coats. After the third coat has dried, dip a small
pointed brush into the same or a different color halo metallic and touch the
tip of the brush to the piece. This causes the earlier coats to break up
into halos with soft edges that fade into the background glaze. Do not
thicken or thin! Use only dark colored glazes under halo metallics, or
you will not get the right color. (This doesn't apply to halo lusters)
Fire to Cone 018.
Opal and Mother of Pearl: Apply a thin,
unveven coat. Fire to Cone 020/019. Each creates a layer of
purple/pink/green/blue highlights over the surface of the underlying
glaze. Opal is the finest, lightest pattern. Mother of Pearl is
more pronounced. If you are looking for a Mother-of-Pearl that has the
brightest colors, we recommend the Mardi-Gras (it is the last
item on this page)
Lustres: Apply 1 even coat, medium thickness.
Fire to Cone 019/018.
