Solar heating for adinkra ink production in Ghana

Ron Eglash, Edward Antwi, Lawrence Darkwah

ink boilingAdinkra are symbols used in a stamped cloth process in Ghana. The ink is created by soaking bark in water, straining out the bark and then boiling the remaining water in huge pots. The fire burns so long and hot that old engine blocks have to be used to prop up the pots, as you can see in this photo. Replacing fire with solar means less income loss, less deforestation, less Carbon emissions.
