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.
