  • This study investigated the effects of lacquer-finishing to prevent discoloration of coloring chestnut wood coated with natural dyes from deteriorating factors such as lights (indoor, 500 lux and outdoor, 50,000~70,000 lux), acid, alkali, and heat through measurement of color difference. Lacquer-finishing coating contributed to protection of intrinsic color of the natural dyeing woods in spite of severe treatment. In particular, dyeing liquor with alkali pH played a great role in prevention of light discoloration.

  • From the low swamp remains in Sinchang-dong, Gwangju, a number of wooden lacquerware along with various wooden artifacts were excavated. These excavated lacquerware have deteriorated and weak wooden parts and the lacquer layer come off from the wooden parts; they are very likely to peel off and crack. Therefore, we impregnated the lacquerware in PEG#4000 40% solution that was effective for vacuum freeze drying and finished freeze-drying below 0°…. We compared the weight of wood and lacquerware right after the freeze-drying with the weight after leaving them in a airtight space with 60% RH (relative humidity). The comparison results showed no change in weight; thereby we confirmed controlling the finishing temperature during freeze-drying could control the moisture in wood after drying and it could stabilize wood against the change in moisture in the atmosphere. according to the analysis of the lacquer fragment, the base layer was pasted on the wooden surface with mixed black pigment and the upper layer was pasted three or four times with the mixture of lacquer and black pigment; or it was pasted without the black base coating.

  • Gachiljang(假漆匠), along with Jinchiljang(眞漆匠), is an important craftsman who cannot be left out during the finishing process of wooden furniture and wooden buildings during the Joseon Dynasty. The current definition of Gachiljang does not properly explain the nature and role of Gachiljang. In many related terminology dictionaries, Gachiljang is defined as "artisan who dose the base paintwork of Dancheong." But an analysis of the Joseon Dynasty's Uigwe(儀軌) shows that Gachiljang appears frequently in works that are not related to Dancheong at all. Therefore the current definition seems to be inaccurate and need to be revised. Gachiljang is a name that contrasts with Jinchiljang, and he makes and paints Myongyu(明油). Just as Jinchiljang uses not only lacquer but also various pigments to paint colorful lacquer, Gachiljang also uses various pigments to decorate buildings or furniture in a fancy way and then finishs with a transparent paint. Even in the Dancheong(丹靑) work of the building, all the base painting and finish coating work will be in charge of Gachiljang, except for the paintings performed by the Whawon(畫員) or the Whasa(畫師).
