We produce eco-friendly Natural Indigo Fabric Dye, by extracting it from the plant Indigofera Tinctoria". We have mastered this ancient famed craft. The process of manufacturing indigo fabric dyes includes the following steps: The fully grown plant is cut and soaked in tanks of length 14ft and breadth 14ft depth 2 feet. After 18 hours of soaking, the green color of the leaves comes out of the leaves and lies mixed with water. This leaves-extract along with the water is led into another tank of similar dimensions and oxidized by agitating the green water by kicking with the legs. This manual process continues for about 1 hour to one and a half hour, By then, the green leaf extract turns blue in color and thickens noticeably. This thick Gravy is transferred into a copper vessel and boiled at a high temperature for one hour. then it is poured into molds.
