Logwood Extract 100g (3.6 oz)

Logwood is a bushy, thorny tree grown in Mexico, Central and South America and parts of Africa. The purple dye is concentrated in the heartwood of the tree. Dyeing: For a medium to dark colour use extract at only 1-2 % WOF on mordanted fibre. Dye at temperatures no higher than 180 F and for no longer then 60 min or the colour will lack clarity and luminosity.

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%.
