Lisht is one of a few New Kingdom sites with known glass‐working debris. Here, we present evidence for the primary production of glass at Lisht, including crucible fragments and semi‐finished glass. We also provide 12 new chemical analyses of glass from Lisht, including trace elements. We argue that the glass made at Lisht has a specific chemical signature within the broader range of Late Bronze Age glass compositions from Egypt, further underlining the former existence of primary glass production there and offering the possibility of identifying Lisht‐made glass elsewhere in Egypt and beyond.
