The craftsman then filled the hollowed out area with a green or blue enamel liquid paint with a brush. After baking the enamel pigment in a furnace with a temperature of up to 800 degrees Celsius for a certain period of time, a translucent glass-like effect is obtained. After it has cooled, place it in water and grind off the excess enamel with hard stone sandpaper. Then, the dial is first polished by hand with a diamond file, and then the last baking is performed. This process is called dorure, which makes the enamel shine brightly. William Harrison’s sailing route from Europe to the Americas is carefully traced with silver powder.
