1. Indigo Production Marker

Inscription. Vats and drying racks were used for the production of indigo. The vats were large, holding up to two thousand gallons of liquid. The stems and leaves were cut and laid in the larger vat. The stems were covered with a urine and water mix and left to soak. The liquid darkened to a gold or olive color. After eight to twelve hours the liquid was drained into a lower vat and limewater was added and the liquid was violently beaten. This added air to the fluid turning it blue. The indigo settled to the bottom of the vat as a sludge. After a few days the clear water was drawn and the residue of indigo was scooped into linen bags and hung to dry. After it reached a pasty consistency it was spread out on boards to dry and harden. Finally it was cut into small blocks for shipping.
