Floral ornamentations in relief are formed by pursuing and punching away the background around the relief work on the surface of plain or gilded brass or copper objects. The chased portions are then filled with black lac, fused with a hot bolt, and the surplus scraped away with sandpaper or powdered brick. As a result, a little dazzling floral design against a dark background is created. Marori is the name given to this type of craft. The opposite of this is chrakwan which is when the pattern is in black or any other coloured lac with a copper or brass background. These are two Rajastha-based metal engraving crafts that evolved during the medieval period, inspired by the Mughal and Rajput cultures.
