It is used in the restoration of old documents, the preservation of calligraphy, pictures and reliefs. Generally, paper is bleached with chlorine, and the very small amount of chlorine left in the paper causes it to fade, discolor, and deteriorate over time. Our “chlorine free” tengu is bleached in our own original way, without the use of chlorine or fluorescent dyes. With repeated rinsing of the material, a weak alkaline solution removes impurities that cause deterioration. Bleaching increases the ability of colors to stand out on paper. This paper is suitable for long-term storage of important records and restoration of retrofit work.
