Dye With Logwood

(Haematoxylum campechianum)

Logwood comes from a tree native to the West Indies and the Yucatan Peninsula.

With alum it gives purple to blue purple, however do not use cream of tartar in the mordanting process as it will turn the purple colour to brown.

Logwood contains natural tannin and is therefore effective on both protein and cellulose fibres. It is especially beautiful on silk.


  • 100g of mordanted wool
  • 50g of logwood powder


  1. Cover the logwood with boiling water and stir well. Leave to soak overnight.
  2. The following day add the logwood to a stainless steel dye bucket containing 10 litres of cold water, and gently bring to boiling point, reduce heat and simmer for an hour. Turn off the heat and leave it to cool.
  3. Whilst it is cooling soak your mordanted yarn in tepid water.
  4. Now add the soaked yarn to the dye bucket and simmer for 30 minutes.
  5. Allow to cool and remove the yarn, wash and rinse.
  6. The dye remaining in the bucket can be used to dye a further batch of yarn a lighter shade.
