A high pressure method to produce bulk chalcogenide glasses of a unique AsS composition has been developed. The structure, optical properties, and stability of the obtained glasses have been studied. Glasses have an intrinsic deep-red color, opticalpseudogap Eg1.75 eV, a broad Urbach absorption tail W $_{U}$ 120 meV, and high temperature stability up to 130 $^{circ}$ C. AsS glasses show photoinduced transformations, including photocrystallization. The glass structure is largely based on the quasimolecular As $_{4}$ S $_{4}$ units with partial polymerization providing an example of an inorganic molecular-based glass.
