Iridescent Lidded Pot by John Dermer

• Iridescent Decoration of Porcelain - Iridescent decoration of porcelain is a technique in which a thin layer of metallic glaze is applied to the surface of porcelain to create a shimmering, rainbow-like effect. The metallic glaze is usually made with a mixture of metal oxides, such as gold, silver, or platinum, that are fused to the surface of the porcelain during firing.
  
  This technique was first developed in the late 19th century, and was particularly popular in Art Nouveau and Art Deco styles of decorative art. Iridescent decoration of porcelain can create a wide range of colours and patterns, depending on the types of metal oxides used and the firing techniques employed. It is a highly skilled and labour-intensive process, requiring a great deal of technical expertise and attention to detail. Today, iridescent porcelain remains a popular and highly valued form of decorative art.

Compare with engraving where the surface is cut with a sharp instrument such as a metal needle or rotating tool to achieve a fine indentation.
