Logwood, Chips


Dried and cured chips from a tropical tree, Haematoxylum campechianum.

Use on protein or cellulose fibres. Pre-mordanting essential. Produces dramatic pink, blue, maroon and purple to black shades. Use at 20-50% WOF for medium shades.

TO USE: place chips in a stocking and soak overnight in cold water. Bring to a simmer for 1 hour, cool and remove stocking. Enter premordanted fibre and simmer for 1 hour. Bath may be used for successive dips, and by the 3rd or 4th dip the colours being yielded change to golds, greens or browns.

Light and washfastness: average. Keep dyed fibres away from bright light.

NEW: Logwood Extract: this has already been soaked out then reduced down to a powder. It’s expensive but very strong and super convenient. Simply weigh out the extract at around 10% weight of fibre for medium shades, or adjust for darker or lighter. Dissolve in a measuring cup with hot (but not boiling) water, add to your dyepot with water, mix well, add your fibre and simmer for an hour.
