Abstract

Yeonpyo-beob is a method of manufacturing pigments using bamboo trunk and glue solution. Glue solutions of concentrations 1, 5, and 10% were employed to manufacture pigments, and the characteristics of pigment manufacturing were analyzed according to these concentrations. The pigment manufacturing process can be divided into holding and drying phases. The holding phase involves the sedimentation of relatively large particles, whereas the drying phase involves the sedimentation of small particles. The layers formed during the drying phase have almost similar forms regardless of the concentration of the glue solution. If the concentration of the glue solution is low in the holding phase, the particles are mixed and the formation of a layer is difficult. In contrast, when the concentration of the glue solution is higher, the layer of the pigment is more distinct. These results confirmed that the differences in viscosity due to the variation in the concentration of the glue solution affect the sedimentation velocity of the pigment particles, thereby affecting the formation of the layer of the pigment and the pigment manufacture. Consequently, applying 10% glue solution to reduce the sediment velocity is deemed suitable for the stratification of the pigment particles and the manufacture of pigments.

연표법은 대나무통과 아교수를 이용해 안료를 제조하는 방법이다. 연표법에 따른 안료의 제조과정을 과학적으로 규명하기 위해 1%, 5%, 10%의 아교수를 적용하여 안료를 제조하고, 아교수의 농도에 따른 안료제조 특성을 분석하였다. 안료제조 과정은 크게 정치단계와 건조단계로 나눌 수 있는데, 정치단계에서 비교적 큰 입자들의 침전이 이루어지고, 건조단계에서는 작은 입자들의 침전이 이루어진다. 건조단계에서 형성되는 층위의 경우 아교수의 농도에 상관없이 거의 유사한 형태를 보이지만, 정치단계에서 형성되는 안료 층위의 경우는 아교수의 농도가 낮은 경우에는 입자들이 혼재되고 층위형성이 어려운 반면 아교수 농도가 높아질수록 안료의 입도별 층위형성이 뚜렷하게 나타났다. 이와 같은 결과를 통해 아교수의 농도에 따른 점성도의 차이가 안료 입자의 침강속도에 영향을 미치며, 이로 인해 안료 층위의 형성 및 안료 제조에도 영향을 미친다는 것을 확인하였다. 결과적으로 고농도인 10% 아교수를 적용하여 입자의 침강속도를 감소시키는 것이 안료 층위의 형성 및 안료제조에 보다 적합한 것으로 판단된다.
