Description
A natural dark blue dye obtained from the Polygonum tinctoria plant native to China, Japan and Manchuria. The colorant in dyer's knotwood is indigotin. Traditionally in Japan, cloth was dyed in a hot water solution containing knotgrass and millet jelly (mizuame) after which it was dipped in cold water to precipitate the indigotin (Shimoyama et al 1996).
