Abstract

Nara sumi is a traditional Japanese craft that has been handed down in Nara since ancient times, and now plays a major role as a regional resource. Soot is considered to be one of the most important materials for its quality. However, the making process has been supported solely by the rule of thumb for craftsmen for many years, and there is very little scientific understanding of that. Therefore, we are focusing on the soot formation process in this study. Soot was collected from different heights in a rapeseed oil-fueled diffusion flame and analyzed by scanning electron microscopy and X-ray photoelectron spectroscopy. As a result, it was confirmed that the formation of the soot shape completes at the bottom of the outside of the flame and that the shape does not change thereafter. It was also confirmed that the oxidation of soot occurs at the bottom of the outside of the flame. These results are expected to contribute to the further scientific understanding of the soot formation process.
