Dyeing the blues

August 23, 2016

The primary natural dye used for blue is indigo.  After looking through my shelves, I decided to do an experiment with anything that might yield a blue.  The color was the primary focus of the experiment so light fastness, wash fastness, … were not considered.  I just wanted to see the array of blues I had on the same material.  The material is a felted wool mordanted at 20% potassium aluminum sulphate.

Weld and dyeing with plant materials versus extracts

August 23, 2016

I dye with natural dye extracts for the most part.  There are a number of reasons for that choice.  I live off grid and roof collect my water.  I live in a high (7500 feet) desert climate.  Some of the dyeing is done in bulk for customers.  I weigh the various options for dye stuffs based on some of the following considerations:

Water is required for the plants themselves, the growing season is short, a fair amount of plant material is required if dyeing quantities of fiber, and there are a lot of rabbits that are voracious.  It is possible to gather local plants in season but then one has to store them and I have allergies to a lot of the local options.

The plant materials often require multiple dye extractions to get the most color from the plant; requiring yet more water.

Most dye plants yield yellow.

It is easier to develop and adjust repeatable recipes with extracts.

On the negative side relative to extracts, one doesn’t know for sure if the dyes are extracted in an environmentally sound way and/or from plants or bugs that are not a limited resource.  One has to trust the dye extract supplier.

There is also the great satisfaction one feels when using plant stuffs that are locally grown or gathered.

As I enjoy experimenting, each year time is set aside to try plant material dye stuffs.  This year, some weld managed to survive the rabbits, drought, and hail.  Last year, the same plant gave less than stellar results but it was worth another try.  The stalks and leaves were cut from the plant and the dye extracted.  Soda ash was added to make the water alkaline.  The result was must better than the previous attempt.  As weld extract is expensive, I don’t often dye with it so in this case, the plant material might work out to be a good alternative.
