This study explored the development of wood furniture made of aged Castanea crenata Sieb. et Zucc, which has been largely planted in the southern area since 1960s and has hardly been used as furniture materials. First, the physical properties of the chestnut wood including specific gravity, stiffness, and shrinkage were compared with Zelkova serrata, Acer palmatum Thunb., Fagus crenata var. multinevis, Quercus, Tagayasan, Prunus serrulata var. spontanea, Juglans sinenis, Pteronrpus santalinus, Diospyros ebenum, and Fraxinus rhynchophylla, which have largely been used in manufacturing furniture. The chestnut wood had appropliate physical properties for wood furniture like other furniture woods. A piece of small table 50 cm in width, 50 cm in length and 60 cm in height by the chestnut tree was created for a current interior space. Since the diameter of the chestnut tree planted since 1960s is below around 30 cm, the top plate of the table had to be put together by an end-joint technique using a small strip. Finally, it is expected that this study will create a greate motivation for furniture designers, furniture studios and furniture companies in Korea to use the woods from the aged chestnut tree in developing furniture in the future.

This study explored the efficient dyeing method of aged chestnut wood using the natural dyes extracted from Gardenia jasminoides for, grandiflora, Carthamus tinctorius L., Rhus javanica L., Lithospermum erythrorhizon S. et Z., Caesalpinia sappan L. and Castanea crenata S. et Z.. The color variation of the dyed chestnut woods was also quantitatively evaluated. The wood specimens revealed abundant colors through different dyeing conditions such as dyeing temperature, dye pH, soaking time, and brushing frequency. The chroma and stain concentration of colored woods were calculated with $L^*$, $a^*$ and $b^*$ in order to make color tone measurement. Brushing treatment for colored wood was confirmed as a more economical dyeing method than soaking treatment requiring more time when natural dyeing was done. Furthermore, the desirable tone and shade of color was easily obtained by repetitive brushing treatment using low color tone. During natural dyeing, good color expression was made with high temperature and acidic condition of a dyeing liquor.

Growth of red pepper (Capsicum annuum) 'Kumtap', tomato (Lycoperisocon esculentum) 'Seokwang', petunia (Petunia hybrida) 'Madness Rose', and pansy (Viola tricolor) 'Magestic Giant' in mixtures of chestnut woodchips and granular rockwool at 25:75, 50:50, or 75:25 (v/v) was examined. Chestnut woodchips were soaked in water for 48 hours or aged in open field for 6 months in order to remove substances impeding plant growth. A commercial plug medium was used as the control. All treatments showed in a similar result in red pepper, petunia, and pansy. Plant height, fresh weight, dry weight, and chlorophyll content in media containing chestnut woodchips, especially in higher proportions, were poorer as compared to those in the control. On the contrary, height, fresh weight, and dry weight of tomato seedlings in media containing woodchips were significantly higher than those in the control. For petunia, pansy, and red pepper, six month ageing in open field of woodchips was more favorable for growth than 48 hour water soaking. Emergance of petunia seed was inferior, especially when woodchip content was higher, to the other crops with a resultant growth suppression. From the results, chestnut woodchips proved to be a practical material as a medium component only in tomato plants.
