Description

Mother-of-Pearl Decorative Plate for Fashion Accessories and Its Manufacturing System and Method

[0001] The present invention provides a mother-of-pearl decorative plate applicable to fashion accessories such as bags, wallets, and shoes, and a manufacturing system and method thereof.

[0002] Najeonchilgi (mother-of-pearl lacquerware) refers to a lacquered wooden product (such as a bowl or furniture) decorated with mother-of-pearl, shellfish shells such as abalone shells, and pearls. It was made in Korea, China, and Japan and is commonly called najeon in the three countries. Another name for it is mother-of-pearl shell. Najeonchilgi is a name according to the technique of decorating the lacquered surface. It is a handicraft made by a technique of reducing or cutting the mother-of-pearl processed from abalone or oyster shells, and then attaching or inserting the patterns on the painted surface by lengthening or cutting them.

[0003] Mother-of-pearl, a natural material, has been widely used since ancient times for high-end surface decorations such as furniture and various personal accessories due to its beautiful and vibrant patterns, colors, and luster. It is said that mother-of-pearl lacquerware requires over 20 stages of work, with painting, drying, and polishing taking anywhere from eight months to a year to complete. The traditional process of making mother-of-pearl lacquerware involves applying raw lacquer to the wood itself. The raw lacquer is made from the sap that flows out when a lacquer tree that is 7 to 8 years old is scratched, and then a mixture of yellow clay and raw lacquer is used to fill in any gaps in the wood. This is followed by a polishing process. To prevent the wood from shrinking, the raw lacquer is mixed with glutinous rice paste and applied to hemp cloth and Korean paper. A mixture of clay powder and raw lacquer is applied to the Korean paper, and this is polished again. This is followed by a black lacquering process. On the rough black lacquer base, a mixture of clay powder and raw lacquer is used to fill in any gaps, and this process is followed by polishing. After this, mother-of-pearl is attached. A coat of a mixture of clay powder and raw lacquer is applied over the mother-of-pearl. This is a flattening technique that ensures that the height of the lacquered surface and the mother-of-pearl are the same. After the priming, middle lacquering, and top lacquering stages and polishing, the surface becomes crystal-like. The process of making mother-of-pearl lacquerware, like this one, usually requires more than 20 steps to complete, making mass production impossible, which leads to a high unit price for the product, making it difficult to apply it in various ways in daily life.

[0004] In addition, when applied to daily necessities, there was a problem that the mother-of-pearl was separated from the lacquer surface, causing the mother-of-pearl to separate, or causing injury or damage to the wearer's clothes due to the sharp mother-of-pearl edges.
