The process of gilding requires meticulous preparation, including priming surfaces and applying thin layers of adhesive before placing the gold leaf.For example, the Church of Nossa Senhora da Conceição dos Militares in Brazil underwent conservation efforts to preserve its gilded surfaces, ensuring the continuation of its religious and artistic significance.Churches throughout history have employed metal leaf for its aesthetic and symbolic qualities, often in mosaics, domes, and religious icons.This tradition flowed throughout the centuries, as European churches used gold leaf to outline the richness and the sacredness of the domes, altars, and sculptures.[8] It's created through pounding metal dust onto parchment sheets and ox guts until it molds into a foil, however it was only up until the 21st century that people have started to stop using intestines.
