"Lacquer" is a material composed of resin from (Kreol Tree), the last resin, water resin, and ash palm leave. That is why we sometimes hear the composition called "Mareak lacquer". Lacquer has been used since ancient times, as there are sculptures and inscriptions describing the use of this lacquer. For example, temple inscriptions. Kork Poti (K, 814), the inscription in Kampong Thom (K. 444), and the inscription of Prasat Chi Kreng (K. 168). Apart from being used for painting luxury and auspicious objects such as “Tork” wooden or golden plate used for holding valuable objects, “Tang Rong” wedding boxes, betel nut and leave boxes, and other everyday items, lacquers are also used to decorate crowns and masks for royal ballet and Lakhon Khol. That is why to this day, although the decoration on the mask of the dance is not made of lacquer, it is still called "mask lacquer". In general, the lacquer masks that are produced often have a giant mask, monkey masks, Ey sei masks, Ream masks, Preah Leak masks, or other animal masks, all of which are used in classical and Khol dance. According to the traditional method, in order to get the mask for the dancer, the clay is first kneaded into the desired shape, then applied glue on paper one layer at a time until another layer is thick enough. Next, left it to dry before removing the sample. However, this type of lacquer can only be used once or twice because the clay mold is easily damaged. After 1960, Mr. On Sok, a professor of "Khmok-Smach" at the School of Fine Arts, came up with the idea of making a mold from cement that can be used for a longer period than the one made of clay. When the mask sample is dried, you need to start gluing paper on it, but before gluing you need to soak the mask with water first to make it easier to peel off. Then use a piece of parchment paper to cover the mask and crumble another paper to glue on it with 10 layers but if the mask is small, it will be glued only 6 layers. The glue known as (Bay Marn is made by cooking rice flour with water). Let the mask dry before peeling, gluing, and sewing. When the mask is completely dried, start drawing ornament details of the mask such as Kbang, crown, ears or called (Jhon Trojeak) all of which are made by the lacquer. To make it you will need to boil Mareak resin, last resin, water resin and ash palm leave together then pour it into Kbach mold and let it cool before using it to glue on the mask. Then apply a layer of tan paint before applying gold foil on the lacquer. In the past, the molds were carved on marble, but later wax was added and cemented instead. The next step is to paint the mask according to the characters and then use a small brush to cut the strands into eyebrows, mustache, ears, and neck. Lastly, holes are pierced in the eyes and nostrils for the performer to see and breathe. Nowadays, traditional mask lacquer making is very rare as raw materials are becoming more and more difficult to find, and lacquer masks are sold at high prices, making it difficult for artists to buy and use them. Therefore, most of the dances that artists wear today are paper ornaments instead of lacquer.

National Intangible Cultural Heritage, Republic of Korea Jewajang refers to the skill of making roof tiles, or to an artisan with such a skill. Roof tiles were used to make the buildings look better, in addition to their inherent function. In olden days, they symbolized the authority and wealth of the building’s owner. Roof tiles are divided into convex and concave types. Ancillary ornamental tiles include convex roof-end tile, concave roof-end tile, roof tile with demon face design, dragon finial, and tiles placed at both ends of the top ridge. Looking at how roof tiles are made, sticky clay mixed water is put into a wooden mold. After a period of drying, the clay is cut to an appropriate size and pattern and then put into a kiln, which is heated to a temperature higher than 1000℃. Adequately baked roof tiles are black or silver gray in color. Each region developed its own unique roof tiles, but concrete or slate-roofed buildings have lately pushed aside buildings with roof tiles. At present, roof tiles are produced only in Ulsan and Jangheung, Jeollanam-do.
