Elastic rubber-like sulfur

Abstract

When a thin stream of molten sulfur superheated above 400° is poured into liquid air, sulfur is obtained in the form of very thin threads, 0.5-1 mm in diameter. The threads taken out of liquid air are at first quite hard and brittle, but then, as soon as the temperature rises somewhat, they acquire extraordinary elasticity, similar to the elasticity of rubber. The easier it is to obtain a body in a gelatinous or glassy form, the more capable it is of giving various modifications. Sulfur is the most typical example of such bodies.
