 note = {The influence of the additon of shirasu (one kind of soil from an eruption, which exists abundantly in Kagoshima-ken) to plastics as fillers was studied. Tensile strength, elongation, hardness were decreased on the case of polypropylen, but impact strength were decreased not so much, and Young's modulus increased slightly. When shirasu was used as fillers after coating by some organic substances (polyvinyl alcohol, cationic surface active agent), the degree of decreasing of above properties were reduced.},
