Fig. 6From: Evidence of early amorphous arsenic sulfide production and use in Edo period Japanese woodblock prints by Hokusai and KunisadaSelected normalized Raman spectra of (a) and (b) orange particles in print B, (c) and (d) orange particles in two other prints from Hokusai Thirty-six Views of Mount Fuji series (respectively JP22 and JP1295) and (e) and (f) from yellow particles in print D. (a), (e) and (f) are characteristic for fully amorphous arsenic sulfide particles while (b), (c) and (d) present characteristic bands for both crystalline and amorphous forms of the pigmentBack to article page
