Ceramic enamels (approx. 1100 - 1200°C) and firing (700-800°C), have been used for decorating porcelain for a long time.

Recently, they have been increasingly supplemented by organic paints. The wide range of shades (including custom colouring) and effects, the resistance in domestic dishwashers (more than 500 cycles) and the certification for contact with foodstuffs make these colours ideal for use in the decoration of advertising porcelain (e.g. mugs).
