This study was carried out to investigate the wood properties for efficient utilization of warm temperate tree species of Quercus salicina grown in Korea. Fundamental wood properties in the anatomical, physical, mechanical and chemical characteristics were examined. Quercus salicina is radial-porous, straight grained and fine textured wood. The heartwood is not clearly distinguished from the sapwood. In physical properties, it has a high oven-thy specific gravity of 0.80±0.03, and high shrinkage from green to air-dried condition of 4.42±0.60% in radial and 10.31±0.50% in tangential direction. Mechanical properties determined are strong with the MOR of 1,170±l44kgf/㎠, and tensile strength parallel to grain of 1,851±236kgf/㎠ and shear strength of 182±10kgf/㎠. Also, this wood has high extractive contents : 10.64% for cold and 12.57% for hot water.

중밀도섬유판(MDF)에 글씨나 그림을 새김질한 목판을 제조하고, 이를 탄화하여 서각작품을 제작하는 방법을 개발하였다. 섬유판의 탄화에 따른 외형적 및 조직학적 변화를 검토하고 제작된 탄화보드 서각작품에 대한 미학적 특징을 고찰하였다. 서각한 MDF를 850°C에서 탄화한 결과, 할열이나 뒤틀림은 관찰되지 않았으며, 치수는 가로 21.8%, 세로 18.8%, 두께 43.5% 줄어들었고, 중량은 69.2%, 밀도는 14.8% 감소하였다. 탄화보드의 전자 현미경에 의한 관찰 결과, 당초 섬유의 표면과 벽공을 둘러싸고 있던 접착제가 탄화되면서 목질섬유의 표면이 매끄럽게 변하고 벽공이 개열되며 섬유의 크기가 균일화되고 조직이 치밀화되는 현상을 나타내었다. 수작업에 의한 서각기법과 무할열 탄화기법의 융합에 의해 새로운 탄화보드 서각작품의 제작이 가능하였다. 탄화보드 서각작품은 목탄의 기능성과 서각의 아름다움을 부여하는 새로운 친환경 예술영역의 한 분야로서 이용될 수 있을 것이다. This study was focused to make a wooden plate that is engraved with writings or pictures on the medium density fiberboard (MDF), and then to produce a calligraphy-carving artwork by carbonization of the carved MDF. The external appearances and anatomical changes were investigated on the carbonized MDF and aesthetic characteristics was also discussed. No split and no twist were found after the carbonization (at 850°C) of the calligraphy-encarved MDF, shrinkages of the MDF were observed with portions of 21.8% in length, 18.8% in width and 43.5% in thickness, and 69.2% of weight loss with density decrease of 14.8% were observed as well. From the observation of the carbonized board by a scanning electron microscope, specific phenomena were found: the adhesives, surrounding the fiber`s surface and pits, were carbonized, the woody fibers were changed smoothly, the pits were opened, the fiber`s size was uniformized, and the organization was compacted. By the combination of handmade calligraphy-woodcarving and crack-free carbonizing methods, it was able to find a new method for manufacture carbonized calligraphy-woodcarving artwork. It is concluded that the calligraphy-woodcarving artwork using carbonized board can be a new access for the eco-friendly art that has the advantage of the functionality of charcoal and the aesthetic of calligraphy-woodcarving simultaneously.
