The invention resides in a molecular, inorganic glass and a method of making the glass, the glass being vitreous and resistant to devitrification, that is composed, in substantial part at least, of thermally-stable, zero-dimensional clusters or molecules, composed of four atoms of arsenic and three atoms of sulfur, the glass further containing up to 12 atomic percent of germanium, adjoining clusters being bonded to each other primarily by van der Waals forces, and at least 95% of the glass composition consisting of 42-60% arsenic, 37-48% sulfur plus selenium, the selenium being 0-14%.
