Jan Kosiński worked in Krosno glassworks for only three years (1960–63). Despite the modest number of preserved works, his individual style seems relatively easy to define.
Kosiński prefers hand-moulded glass – decorative vases and decanters with impeccable drawing mark an excellent use of the properties of the material. These are usually slender moulds with massive bases and softly modelled asymmetrical spouts. He often uses internal underlay glass, with the colour distributed unevenly – darker in the lower and upper parts of the vessel. The artist was also one of the first designers to introduce spectacular handles and openwork. Occasionally he also deals with engraved decoration; however, not with crystal glasses, but thin-walled glasses made of smoky sodium glass.
