Arsenic‐sulfur‐iodine glasses, recently described by Flaschen et al., were prepared and exposed to various neutral, acidic, and alkaline solutions. Chemical durability, reported in terms of weight loss per unit of surface exposed, was correlated with glass composition, test temperature, exposure duration, and solution pH. Physical properties, such as density, melting temperature, deformation temperature, linear thermal expansion coefficient, and relative fluidity at melting and room temperatures, are also reported. These low‐melting inorganic glasses were found to exhibit excellent resistance to moisture and to acids, including hydrofluoric acid. On the basis of interpretation of the test data, the structure appeared to be a random arrangement of long‐chain sulfur and branched‐chain arsenic‐sulfur polymers.
