Hard enamel color and metal lines are almost at same height, hard enamel pin surface feels smooth and weaker metallic than soft enamel.
Same as soft enamel, hard enamel pin can also be plated with different metal colors, such as nickel, silver, gold, brass, copper, rose gold... but hard enamel pin cannot do dying color on metal. Because for hard enamel pin, the plating process comes after the process of coloring, and before plating, there is a very important step that make it completely distinct from soft enamel - POLISHING, the function of polishing is to make the raised metal and hard enamel color at same plane, that’s the secret why hard enamel pin has a smooth surface, so for hard enamel pin, even the metal is dyed, the color will finally be rub off during polishing.
Hard enamel is suitable for most pin badges, coins, keychains, medals, tags, cufflinks and other metal products.
