Coating with luster: Luster is an organometallic compound. Luster is applied to the substrate by painting, spraying or dipping. After loading, the luster is fired at temperatures of 500 - 650 ° C. Firing temperature depends on the kind of luster. Colour luster usually fired at lower temperatures (500-570 ° C), "metallic" luster (gold, platinum, bronze) require higher firing temperature (570-650 ° C). When firing leads to burning of organic components luster; metal component is oxidized with atmospheric oxygen on the respective metal oxide. After firing the substrate remains on the surface of the metal oxide thin film whose adhesion to the substrate, the color and overall looks can be affected by the chemical composition of the substrate.
