An eighteenth-century encyclopedia article on bleaching linen cloth and thread, as practiced by Scottish bleachers. It describes the sequence of steeping, bucking and boiling in alkaline lyes, alternate watering and drying on the field, souring with buttermilk, bran or vitriol, soap washing, and starching and bluing. It then discusses the theory behind each stage, citing experiments by Dr Home on wax bleaching, lyes, acids and lime, and closes with a method of bleaching safely with lime.
