Formosul or Formasol is the active component of Discharge Paste mixed with a thickener (Indalca PA3R) and used for colour discharge of selected areas by printing, painting or areas of resist. Some reactive dyes do not discharge and some give a simple colour change.
Method for making 1 litre of Discharge Paste:
- Mix 150g Formasol to 200ml water to a smooth cream
- Mix 60g Indalca PA3R into 600ml water and blend with an electric mixer to make a stock paste.
- Pour the prepared Formasol solution into the prepared Indalca PA3R solution and stir to combine.
The Fibrecrafts Dischargeable Acid Dyes are designed to be easily removed by this paste recipe. The Fibrecrafts Illuminating Acid dyes are designed to be combined with the discharge paste so that the new colour in the paste replaces the original colour as it is removed! Â
