Mordanting: Use alum mordant at 15% WOF for protein fibres. For cellulose, first mordant with tannin at 8% WOF, then either 1) use alum at 15% with soda ash at 2% or 2) use aluminum acetate at 8%.
Dyeing: Use at 20-30% WOF for a medium depth of shade. Add the dried flowers (in powder form) to the dye pot, cover with water and simmer for half an hour to extract the colour. Strain the dye liquid and add to dye pot. Add fibres and simmer for 30 - 60 minutes. With the addition of iron at 2% WOF warm olives can be made.
