National Intangible Cultural Heritage, Republic of Korea The term chiljang refers to the craftsman who creates lacquerware by applying lacquer -- or the refined sap of lacquer trees (Rhus verniciflua) -- to various objects. The first trace of lacquer use dates back to the third century BCE, but the earliest relics of lacquerware date back to the first century BCE. Lacquerware began to develop into an art form during the Nangnang (Lelang) Period and progressed further in the Silla Kingdom. In the Goryeo Dynasty, lacquered works were decorated with mother-of-pearl inlay, creating a new art form called najeon chilgi. In the Joseon Dynasty, lacquerware became more common, and many works were produced. The state compiled data on the distribution of lacquer trees nationwide and collected the sap from these trees. Lacquer craftsmen working in the capital and in the provinces were affiliated with their local government offices. The raw lacquer from the trees had to be refined before it could be used, and lacquer craftsmen would do the refining themselves. The refining process removes impurities and creates a fine particle liquid. Creating lacquer works is a long, laborious process. The item to be lacquered, called soji, had to be made of materials that are easy to work with and to paint, including wood, bamboo, cloth, paper, clay, and metal. First the object is smoothed down, and then the lacquer is built up in many coats, requiring lacquering, smoothing, and drying over and over again. Basically, the process is divided into three steps: chochil (first lacquering), jungchil (middle lacquering), and sangchil (final lacquering). After the final coat, the object is vigorously polished.

Lacquer painting in Tương Bình Hiệp was brought to this land by the people from the North and Central regions around the end of the 17th century. Wood is the base material for lacquer. The product is made through 2 stages of painting and polishing by hand. There are many types of lacquer such as lacquer painting, sunken painting, thin painting, hollowed out, embossed, and the most prominent is eggshell inlaid lacquer... A qualified lacquer painting must go through 25 stages that require meticulousness and elaboration. Depending on the type of product, the core will be made of different materials, such as wood used to make tables, chairs, cabinets, vases; plywood used to make paintings, boxes; ceramic used to make vases, statues; fabric or paper used as the core for products with light, thin designs such as bowls, plates, vases. The images drawn on the paintings are images close to the real life of the people such as landscape paintings, banyan trees, wells, communal houses, countryside, historical stories. All have created products with their own unique style.

The Lacquerware Making in Cát Đằng was born more than 600 years ago (from the end of the Tran Dynasty) associated with festivals to worship the village's ancestors (the founders are Mr. Ngô Đức Dũng and Mr. Ngô Ân Ba) and annual ceremonies taking place on January 14-16. Rich materials: wood, rattan, bamboo, reed... The main material is lacquer processed according to a secret recipe. It takes the craftsman a month or more to complete a product. Wooden objects for lacquer are not nailed but only use mortise and tenon joints with paint mixed with sawdust. Of all the stages, the most outstanding skills/techniques of the lacquer craft are the way of mixing paint, spraying paint, gilding gold, silver, inlaying, and drawing. These are also the most typical secrets of the Lacquerware Making in Cát Đằng. To make a product of the craft village, it is necessary to have the main materials such as: lacquer, tung oil, resin, sawdust, soil... Materials for making the core (vóc): wood, bamboo, rattan. Decorative materials: gold leaf, silver leaf, pearl shell, snail shell, egg shell, etc. Tools for making lacquer: beak, bucket, earthenware pot, etc. Tools for making lacquer: steel hair, sandpaper, whetstone, broom, curtain cloth, jackfruit leaves, xoan charcoal, tangled hair, paring knife, slotting knife, iron rod, etc. Decorative tools: cat hair pen, steel hair, slotting knife, etc. Currently, in addition to traditional lacquer materials, mainly industrial paints such as PU, cashew nuts, Japanese, etc. are used, and there are many other supporting tools such as: peeling machines, quilting machines, sharpening machines, sanding machines, paint sprayers, etc. to make bamboo patchwork products. The products of the craft village currently include two main product lines: Fine lines goods (worship items) and patchwork goods (handicrafts).
