Carrageenans and various other polysaccharides were characterized by differential thermal analysis in an atmosphere of air. The carrageenans, although isolated from different sources, had essentially the same thermographic characteristics. Of the other compounds studied, such closely related polysaccharides as amylose and amylopectin showed widely different thermal behavior. Thermographic replication was highly satisfactory.
