While several studies concerning Urushi have been conducted all over the world -, very few focused on Maki-e. It is a decorative technique that was developed originally in Japan however, other Southeast Asian countries, such as Korea and China, also have similar style and techniques for lacquer craft. Maki-e is a drawing technique that uses the natural lacquer Urushi and metal powders. Lacquer craft is a typical traditional craft of Japan.
Urushi, Natural Lacquer, Maki-e, Silver Powder, Energy-Dispersive X-Ray Spectroscopy It was shown that sulfuration on powder surface can be removed by polishing irrespective of the shape and chemical composition ratio of the particles. Wakou silver has a very strong resistance to sulfuration however, owing to its Pd content, its chroma is much lower than that of other powders. 1) manufactured by the two companies are different and it affects the occupancy rate of Urushi and powder, which in turn affects their gloss and color. The study revealed that the shapes of the silver powders (Maru-fun, No. In addition, to verify the effect of polishing, residual gloss after sulfuration and polishing was measured. Gloss and color of each silver powder were measured after Maki-e decoration was finished, and EDS (en- ergy-dispersive X-ray spectroscopy) was used to determine the differences in their chemical composition. In 2014, there exist only two companies that manufacture silver powder for the purpose of Maki-e, and this study focuses on comparing the powders manufactured by them. Maki-e is a traditional Japanese decorative technique that uses the natural lacquer Urushi and metal powders. Received 27 October 2014 revised 20 November 2014 accepted 10 December 2014

This allows for maximal deconvolution while not losing components because of 'over deconvoluting'.1Department of Advanced Fibro-Science, Kyoto Institute of Technology, Kyoto, JapanĢFuture Applied Conventional Technology Center, Kyoto Institute of Technology, Kyoto, JapanĮmail: * © 2015 by authors and Scientific Research Publishing Inc. The width chosen happened to be slightly narrower than those used in curve fitting (see below) the spectrum of interest. In the present case the broadening function was chosen to be a symmetric Voigt function" with 20% Lorentzian character.
the convolution of the broadening function and the current deconvoluted spectrum). The most important variable in any deconvolution is the broadening function. The Jansson algorithm implements an iterative type of procedure that can be controlled interactively by a visual evaluation or by monitoring the residual variance between the original data and the reconstructed data (i.e. The backgrounds were removed using a Shirley-type integral and spectral smoothing was carried out using a cubic All data analysis programs (GOOGLY Software) were written in house by A.P. Pretreatment includes background removal and spectral smoothing. Catalysts by XPS using Curve Fitting, Deconvolution and Factor Analysis"-" In order to achieve a successful deconvolution, each spectrum must be pretreated.
