Lead Came: Window Rods Cast in a Split Wooden Mould (Theophilus, tr. Hendrie 1847)

Theophilus' way to cast window leads without an iron mould: a stick of fir is split, a groove marked with a red-dyed flax thread and cut along both halves, the halves bound with a strap and the lead poured in again and again until the hot lead has burnt the groove to the bottom. Each rod is then trimmed in a slotted wooden gauge, cut with a knife on both sides and scraped smooth. Source: Theophilus, De Diversis Artibus, Book II, ch. XXVI, tr. R. Hendrie (1847), pp. 149-151.
