a) Burnished high-temperature golds are designed for 1180–1230°C burning. Burnishing the heated metal layer gives these gold embellishments their rich silk matt golden look. The burned high-temperature gold layer is much thicker than brilliant or matt gold metal layers. Many gold ornaments are yellow red because of the high firing temperature. White gold alloys of gold/platinum or gold/palladium powder are also obtainable at high temperatures.
b) Bright gold preparations are precious metal-based metalorganic compounds dissolved in resin and oil. Bright golds come in lemon, yellow, yellow-red, copper, and rosé. Bright golds are applied on substrates in various ways. Apply liquid brilliant gold to the brushes. Direct screen printing and decal manufacture use dazzling gold pastes.
