Ingredients:
6g alum powder
6g cream of tar tar
Fabric
Method:
Wet the fabric that you intend to mordant to help loosen the fabric so that the mordant will attach itself to the fibres and get evenly to the fabric.
Weigh out your 6g of alum powder and the cream of tar tar and place these in a small pot and add some warm water to this to help dissolve the two powders.
Fill a pot up with water enough water so that the fabric can freely move around the pot. Bring the pot to a boiling point and then back down to a simmer.
Add the now dissolved alum and cream of tar tar to the pot and stir around the pot
Add the fabric to the pot and leave in the pot to mordant for about 45 minutes to an hour.
Take the fabrics out of the pot once the 45 minutes are up and then rinsing and hang to dry.
