Sappanwood (Brazilwood) Dye

Caesalpinia Sappan

Dye Package Weight: 50 grams
Colours: Reds, Pinks, shades of colour.

Sappanwood is a small shrubby tree that thought to be native to regions between central and southern India, Burma, Thailand and southern China.
Brazilwood or Sappan wood can be used to dye shades of Reds and Pink. The colours will vary depending on the growing conditions of the trees, the pH or alkalinity of the dyevat, concentration of the dye and length of time the fibres have been in the dye vat.
Sappanwood or Brazilwood yields beautiful red colours but can be sensitive to light. Brazilwood was often overdyed with madder to give more sustainable red colours.
To Dye 100 grams of yarn, I generally use 10 grams of dye powder. For stronger colours, you can add more dye powder. After dyeing the yarn, the dye bath can be used again for lighter shades of colour. Re-use the dyebath until the dye is exhausted. Or over dye with other colours(such as yellow or blue) to produce different shades of colour.
Nothing is wasted.
When dyeing with natural plant dyes, a mordant must be used to pre-treat all fibres. The mordant allows the fibre to absorb the dye more readily. For animal fibres such as wool, alpaca, silk use a mordant such as alum. Alum is a natural mineral salt and has been used for thousands of years to dye fibres. I use a 10% ratio of alum to fibre. I find that using more than this can result in a harsh texture to the yarn. I also add 5% Cream of Tartar to the mordant bath, as this also helps to soften the texture of the yarn. I reuse the mordant bath several times, adding more water and another 5% of Alum each time I add more fibre. This results in less waste of both water and mordant.
For plant fibres, pre-mordant with a tannin or Aluminum Acetate

Add pre-mordanted yarn or fibre to the warm water dye bath and let this simmer on low for about an hour. Turn off the dyebath and let the yarn soak for several hours or overnight. Natural dyeing is a slow process, not to be rushed.
