What is a Luster? Lusters are over-glazes. This means they are applied to a surface that has been glaze fired. Lusters take on the texture of the underlying surface that they are applied to (matte, satin, or glossy). Lusters are made with complex combinations of metallic salts, resins and oils. These formulations are designed to effortlessly create amazing metallic and iridescent effects.
Axner offers high quality European metallic lusters available in two popular colors. The 8% concentration of metal exceeds most other products on the market and provides excellent coverage and brilliant results.
Firing: Fire the fully dried lusters ware to cone ^018. This should be a fast fire with the peep-holes open. Good firing ventilation is essential for this product. If the kiln does not have a kiln sitter or a programmer, place a cone pack in front of a peep-hole to verify firing temperature.
Application: We recommend a dedicated brush for metallic luster. Apply with a very clean brush over a smooth glaze fired to maturity (for high shine apply over high gloss glaze) observing health precautions as noted on product package.
Mineral spirits are recommended for brush clean up.
