I will have some of my handcrafted soap ( MIM Soap ) and a few bags of madder for sale with this included recipe, but here it is for anyone that would like it.
Madder Root Prep for
Dyeing Wool
Yield: 35-100% WOF*. eg. 100 grams of fibre will require
from 35-100 grams madder depending on the DOS** you would like.
There are many methods used to dye with madder. Here is one
example how to dye a protein fibre:
Prepare the
fibre/skein:
Scour yarn or fibre.
Mordant clean fibre/yarn with alum (potassium aluminum
sulfate) as your instructions recommend. Rinse.
Fibre or yarn for dyeing must be soaked at least 1 hour.
You probably would want to place the fibre in a mesh bag or
strain the dye first to remove the root matter.
Prepare the dyepot
by adding to 4 l. water to a large pot (stainless steel or enamel) and soaking
the roots overnight.
For best colour results the water should be hard. If you
don’t have hard water you can add a little calcium carbonate (or one Tum’s
tablet) to the water along with the roots.
Alternately, you can grind the roots in a non-food blender
with some of the water first, doing a little at a time before adding to the
dyepot. Soak overnight.
When roots & water have been combined & have soaked
overnight, slowly raise temperature to 140F for 1 hr.
Add fibre and continue cooking at 140 for 1-2 hrs.
Temperature is important because higher temperatures will
bring out brownish reds – so do not go above 160F.
At the end of this time the fibre can be removed and cooled.
Let sit overnight & rinse the next day.
*WOF= weight of fibre
**DOS=depth of shade
100 grams=3.5 oz.
113 grams=4 oz.
