Discharge technique in fabric is to make the design pattern on dyed fabric by chemical means.  Diluted sulfuric acid agent is painted with a brush directly on the indigo dyed fabric.  Chemical reaction takes place as the acidic agent get in contract with the indigo dye.  The acidic agent will then discharge the indigo pigment, leaving a white pattern.  This method of pattern making allows more freedom in expression.  But most of the time, stencils are used in production because of labour.  The discharge fabric is finally rinsed in an alkaline bath to remove the acidic remains.

Here is a DIY version of the same technique, you can try it at home!

Discharge Dye Fabric are shown at the Mountain Folkcraft shop in our Something New Something Old exhibition with Soil.
