| Uemura's notes | The sample was firstly soaked in a bath containing dye extract and ash water. Subsequently, the iron mordant was added to the dye bath. If ash water alone was used in the dyeing process, the resultant color would be pale red beige. If smaller quantity of ash water and larger quantity of iron mordant would be used, the resultant color would become dark brown. |
