Application could be done with brush, spray, sponge or any other method suitable to coat the substrate. The solutions are formulated to the right consistency and come ready to use: one coat, one fire. Application by either brushing or spraying is the most common. The lusters are true liquid and any sediment that may be present at the bottom of the container must be left undisturbed. Do not shake the container. The ware must be clean and dry (if not wash with soap and final rinse with distilled water from a squirt bottle then let dry). The presence of moisture, dust, lint, fingerprint, etc. will mar the appearance of the fired film. Use fine bristle brush such as camel hair or sable. Dip brush in solution and lightly scrape off excess against the lip of the jar. The brush should hold enough solution to apply an even coat with brush marks well leveled. Do not rework coated area once it gets tacky. Due to differences in basic compositions the lusters come in varying consistencies and workabilities. Lusters that may have lost some solvent and thus appear thick and tacky to apply can be conditioned with a few drops of Essence (thinner). Caution: Use of Essence other than SARA’s may not be compatible with the luster and dissociation of the ingredients may occur. Spraying may need thinning of some of the solutions. Dry compressed air at 10 to 20 pounds pressure is required. Spraying distance will vary depending on ware size. Lusters specifically made for spraying are available. Sponge or stamp could be used by transfer from a tile spread with luster. Once the properties of each luster color are known. Special effects are innumerable and produce decorations that are not attainable by any other means. Clean brushes and equipment with SARA Brush Cleaner.
