Luster colors for Porcelain Painting and GLASS Painting. Lusters are thin, washes of color which when fired, will give you a beautiful, transparent color. Lusters sit on the top of the glaze, so are more delicate when handled; do not put in the dish washer. Use OH1 Essence to thin when necessary. ALL Lusters have a “shelf life” so keep in cool location with the lid tight to make it last longer.
Thin coats are best. Fire inbetween coats. Porcelain Fire – Cone .017 – .018. Glass Fire – Cone .022. Use separate brushes for each color, OR, you can clean the brush out VERY thoroughly with Acetone Cleaner or the acetone free nail polish remover. Some teach to use 3 different bottles of Acetone, with #1 being the “dirty” first cleaning; #2 – medium cleaning, and #3 bottle the final cleaning. This does work pretty good. Blot out all cleaner before putting into the Luster bottle.
Manufacturers advise NOT to shake or stir lusters, but to let any contaminants settle to the bottom and use right off the top of the liquid. Remember a little goes a long ways so only fill the very end of your brush and let it flow onto the porcelain or glass. THIN coat applications. Do long stokes; slightly overlapping the last stoke to let the color flow together. Do not go over your stroke; do not try to blend. Let dry before firing; venting kiln until last 30 minutes.
No returns on Lusters. We recommend you test fire all lusters.
