Decalcomania ("Decal"), from the French décalcomanie, is a decorative technique by which engravings and prints may be transferred to pottery or other materials. It was invented in England about 1750 and imported into the United States at least as early as 1865. Its invention has been attributed to Simon François Ravenet, an engraver from France who later moved to England and perfected the process, which he called "décalquer" (derived from French papier de calque, "tracing paper").

Patience and concentration are essential human qualities needed at this stage to maintain the accuracy of the placement of the pattern. Then it is exposed to a third round of firing known as decal firing. The paper is burnt and the pattern with overglazed colours is transferred to the surface of the piece. Hand painting by skilful artists gives a touch of uniqueness to each product. The gold lining is another task that requires skill. Delicate fingertips are well trained to move the pointer brush along a perfect path. This brownish coat converts to gold once burnt. The end product is finally inspected at this stage before being sent for packaging. No room is left in the production process for slipping in an inferior item to the market.
