An encyclopedia article on bleaching linen and cotton cloth and yarn, published in the Encyclopaedia Perthensis. Part I describes the traditional method: steeping, bucking with alkaline leys, grass bleaching, souring with buttermilk or bran, then vitriol (sulphuric acid) souring, rubbing with soap, and starching and blueing. It discusses the chemistry of leys, ashes, lime and acids, citing Dr Home and Dr Black. Part II covers M. Berthollet's new method using dephlogisticated (oxygenated muriatic) acid, with its apparatus, procedure, advantages and costs. An engraved plate shows bleaching apparatus.
