An encyclopedia entry on taffeta, a fine, smooth silk fabric with a characteristic lustre. It lists varieties (alamode, lustring, striped, flowered, Chinese and Hungarian types) and the main production centres, and gives the legend of Octavio May of Lyons discovering the glossing process. It also describes the stretching and heating machine used to give the gloss, the liquids used for black and coloured taffetas, and the Chinese taffetas glossed with porpoise fat.
