Chestnut
Castanea sativa
Chestnut Extract Chestnut trees grow in many parts of the world and contain a great source of tannin. They dye a warm brown colour. This dye is also well known for it’s ability to dye silk black with the addition of logwood and an iron mordant. Dyeing: Use extract on mordanted fibre at 5-10% WOF.
See the MAIWA GUIDE TO NATURAL DYES
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 extract on mordanted fibre at 5-10% WOF for a medium depth of shade.
