The fruits of Buckthorn are also known as Persian berries and the juice of these unripe berries is historically used to make the pigment known as "sap green". Buckthorn can be used to create a range of shades including orange-yellow, yellow, beige, green, and khaki, depending on the mordant and modifiers used.
Dyeing Processes
- Pre mordant: Pre-treat the materials with alum 15% of fabric weight at 80°C for about 60 mins. The addition of 5% cream of tartar during mordanting will improve light fastness.
- Dyeing: Use buckthorn ground on mordanted fiber at 15% of fabric weight, and buckthorn extract at 4-10% of fabric weight until all the color has been taken up.
- Post treatment: Conduct soaping of the dyed material with non-ionic detergent (0.5gpl) for 20-30 mins.
- Hot wash and then cold wash.
