Najeon is an ornamental technique, wherein abalone and clam shells were thinly peeled and sliced into various shapes, and placed on the surfaces of objects. Najeonchilgi, which was mostly used by the royal families and nobility from Goryeo Dynasty through mid-Joseon Dynasty, was popularized by the wealthy merchants during the late Joseon Dynasty. It was applied to furniture and other home goods. The Najeonchil Chest has a lotus vine pattern over the entire lid, and it was used as storage for official or daily costumes. The vine surrounds the lotus flowers in full bloom. It was made by cutting a curved mother-of-pearl according to the pattern, and then hammered onto the surface for attachment (Tabal method). Master Youngjoon Kim’s “Checkered Rectangular Mother-ofpearl Box”, which has changed the idea that Najeonchilgi is old, has produced an elegant texture and exquisite colors with a modern minimalist design. It appeared more three-dimensional with small mother-of-pearl fragments that gave off a bright light. He added color to the mother-of-pearl by dyeing the fabric, and he produced an abstract painting by using the traditional Najeon craft, which radiated a different light according to the angle of observation or the perspectives of the viewers. The light of beauty cherished by the sea is absolutely timeless and radiant.
