The process of mechanical polishing of polycrystalline zinc sulphide with the use of colophony-based polishing resin was investigated. The optimum pressure range is suggested for mechanical polishing. It is shown that the parameters of treatment process and surface quality of zinc sulfide will be greatly affected not only by composition of polishing resins but also by technique of their preparation.
