A technique for preparing section planes of snow specimens dyed with sudan black B was introduced. After the pour space of a snow specimen is filled with aniline and frozen solid, a section plane is microtomed and rubbed with sudan black B powder for contrast enhancement. Compared with previous methods, this technique was simple and provided high-contrast images and reduction of noise on a section plane.
