Yamato

Yamato Indigo is indigo powder dye developed by Aikuma Senryo, a company founded in 1818 in Tokyo. The company was originally an herbal apothecary and later began supplying dyeing supplies. In the 1870s, when indigo was exceptionally valuable, Aikuma Senryo developed a method for extracting the indigo pigments from old indigo-dyed fabric by boiling the fabric in water and creating a clay-like dye called “airou” (indigo wax). Based on this method of making airou, Aikuma Senoryo created Yamato Indigo, a powder dye consisting of extracts from indigo plants (natural indigo), chemical indigo, an alkaline agent, and a reducing agent. Easy to use, the blend has been formulated to mix with only water - no heating, fermentation, or additional agent is necessary. Richly dyes all natural materials such as cotton, linen, silk, leather, wood, or paper into that vibrant indigo that ages brilliantly.

Available in packages of 10 and 50 grams. 10 grams is good to dye the equivalent of up to three t-shirts (depending on desired hue darkness/depth). 50 grams is perfect for a pair of pants.
