  • 오늘날 숯은 알게 모르게 우리 생활에 밀찰되어 많이 사용하고 있는데요. 가정에서 적당한 곳에 숯을 놓아두면 공기를 정화시켜주고, 밥을 지을 때 숯을 넣어두면 찰진밥이되고, 신발장이나 쓰레기통 같은 악취가 나는 곳에는 냄새를 제거해주기 때문에 가정 곳곳에 숯을 놓아두는 경우가 많습니다. 숯 그대로의 쓰임도 좋지만 요즘은 숯샴푸, 숯비누, 숯미용팩, 기능성 숯속옷, 숯베게, 숯장판, 숯벽지, 숯화장품 등 무궁무진하게 숯의 영역이 넓어지고 있답니다. 조상대대로 내려오는 숯의 조상 대대로 전해오는 숯의 다양한 효능을 알아보고, 우리 조상드르이 숯 활용 지혜와 기본적인 효능 그리고 다양한 숯의 쓰임새를 알아보고자 합니다.

  • The identification of species, hygroscopic property, and ability of ethylene gas absorption of 23 ancient charcoals excavated from wooden coffin burials and roof-tile kilns of Chudong-ri cultural site were investigated. All of the 12 charcoals excavated from wooden coffin burials were broad-leaved trees. Among the total 12 samples, 9 samples were Lepidobalanus and others were Celtis spp.. On the other hand, other 11 charcoals from roof-tile kilns were needle-leaved tree, Pinus spp.(hard pine). The broad-leaved tree charcoals from wooden coffin burials showed a higher moisture absorption capacity than needle-leaved tree charcoals from roof-tile kilns. The ethylene gas absorption was greater in the Lepidobalanus charcoal than that of Celtis spp. and Pinus spp. (hard pine) charcoal. The broad-leaved tree charcoal having high absorption ability of substances was due to a large microporous and specific surface area. Therefore, it was estimated that broad-leaved tree charcoals were filled in order to make favorable condition in tomb. The wood quality of pine is soft and easy to burn because of low specific gravity, as well as high calorific value by resin in wood. We could assume that the pine wood was used as fuel for roof-tile kilns because of easy control of heating and thermal power.

  • The article of a book began to make a searching examination in tourism value of charcoal. When I make a searching examination at various angles, as for the tourism value of charcoal, it is incarnated essence of charcoal. In addition, essence of charcoal is the core to select tourism value as. I derived essence of findings charcoal and current events point for cooperation of tourism value, and this becomes the basics that future charcoal sightseeing contents development is strategic.

  • Charcoal burning in the process of manufacture and ordinary use often release many constituent chemical species. As a result of open burning, the chemical composition as well as the physical properties of original material changes through the modification of surface properties of charcoal. Surface modification could be more responsible toward the outside elements for surface adsorption, it becomes easy to adsorb more toxic elements through surface adsorption. In this study, four kinds of commercially available charcoal were studied against the chemical and thermal stability along with the heavy metals and organic hazardous substances. Thermo gravimetric analysis (TGA) and differential scanning calorimetry, from room temperature to $400^{\circ}C$, were performed to study the weight loss and the changes in the behavior of those substances. According to TGA analysis, about 10% of weight loss was happened before $200^{\circ}C$. It was found that related weight loss of this temperature region may responsible to the gas phase organic matter. Natural charcoal, K1 and C1 show 15% of loss during the reaction heated to $400^{\circ}C$, while the artificial charcoal K2, C2 show the weight loss of about 20% was found. This is consistent with the main organic matter and VOC analysis results shown. Chemical composition based on the x-ray diffraction analysis was carried out. X-ray diffraction analysis reveals the existence of chemical additive in the forms of $Ba(NO_3)_2$, $BaCO_3$, and $NaNO_3$.

  • This study was carried out to investigate the effect of packaging materials (general, charcoal) on the physicochemical properties of white, brown and black rices stored at 30'E . The weight losses of the rices were $2.2\~3.0\%$ during storage. The germination rates of the white rice packed with general (GW) and charcoal (CW) were both $0.0\%$, whereas those for the brown and black rices (GB and CB, and GBL and CBL) were 10.3 and $10.9\%$, and 11.8 and $12.1\%$, respectively, after 10 weeks of storage. With regard to the weight losses, there were no differences in the germination rates between the packaging materials. The hardness of the rice increased with increasing storage, but the change was smallest for the CBL (charcoal packed, black rice) and largest for the GW (general packed, white rice). The fat acidity of the rices was significantly increased with increasing storage time and those of the rices packed in charcoal materials were significantly lower than those packed in general packaging materials.
