The research of color properties and the analysis of the regional characteristics regarding the features of the plaster and historical backgrounds

Part2 Measurement of containing oxide and analysis of geographical condition

Abstract

In part 1, through color value measurement of color clay all over Japan, it was analyzed by parameters such as latitude, longitude, altitude and so on. This time, as part2, it is clarified oxides in clay from Aichi prefecture and Kyoto prefecture by measuring color values and component analysis. In areas where special colors are seen, it is presumed that the components having iron content and color characteristics of the soil of mines and hot spring areas are factors. Aiso climate features were analyzed using normal year data of temperature, precipitation and sunshine hours for the period of 30 years from 1981 to 2010. For Aichi and Kyoto's original soil, geological survey was conducted on each harvest site and analyzed based on the geographical history that the land was made.
