On Monday I was driving along the #1 across Saskatchewan and passed by Reed Lake, near Chaplain. It is a Western Hemisphere Shorebird Sanctuary…
As I approached, there were very high winds and the horizon was obscured by the blowing of the sodium sulphate that is mined there…
…and then when I got to the area that was blowing I experienced a total white-out and all I can say is that I was grateful that no one was stopped on the highway or there would have been no chance of avoiding a collision, which I admit would have been my own fault for not having approached more cautiously…
Once home I looked up what is mined there. It is a 99% pure form of sodium sulphate, which is a non-toxic double salt, and can be used as an evener in fabric dyeing (however, it can be an irritant if not used with discretion). Depending on the dye being used it can actually work to deepen/embolden the colour in the fabric.
This morning I phoned the mining operation and enquired about where I might be able to obtain a sample or even a 20 kg. bag with which to experiment. I am waiting for a reply from a local distributor and sent an enquiry to the weaving guild in order to find out if anyone has ever used this chemical?
This post tells about my first dyeing of llama fibre using Lonicera caerulea (haskap) berries. The llama fibre is unwashed white from one of my own llamas, and the berries are from the Tundra selection of University of Saskatchewan haskap grown in my own orchard.
I set up this test using two sets of four samples:
1 – The first sample remained dry and undyed as a comparison.
2 – The second sample was dyed, but was not soaked or mordanted beforehand.
3 – The third sample was prepared by water soak preparation only.
4 – The fourth sample was prepared using a traditional salt mordant (NaCl).
Two samples were prepared from each. This will allow a comparison from each treatment before and after they dry and one is subsequently washed after several days in order to determine colour-fastness of this berry’s properties.
This procedure allowed me to compare later on as a base-line comparison of the simplest sort.
Haskap is a newly cultivated berry that found its way to North America in the 1990’s and is now being intensively bred and selected for at the University of Saskatchewan. Haskap is the name applied to a superior selection of genotypes of Lonicera caerulea. These plants are commonly known as edible blue honeysuckles, and also have been marketed using the name of Honeyberries. Their berries come from flowers that can withstand a -7C freeze and still produce fruit, and the plant is still viable after winter temperatures drop below -40C. It is truly a northern plant and modern plant origins can be traced to Siberia, the Kamchakta peninsula, and the northern island of Japan. The berry’s meat itself is coloured a deep, rich burgundy; it stains anything with which it comes into contact a bluish-purple. The stain can be removed by citric acid. Otherwise it is very difficult to remove. I can find no reference to its use as a cloth dye using a simple internet search. We currently have almost 3,000 plants in our orchard, parts of which are just now coming into full production.
Since aluminum and iron can affect the the dying process (serving as mordants themselves), all utensils and pots used were made out of stainless steel.
The salt mordant (fixative) consisted of 1/16 cup of salt to 1 cup of water (1/2 cup of salt to 8 cups of water for larger batches).
The dye itself consisted of 1 cup of berries to 2 cups of water. This was brought to a boil, the berries crushed, the mix simmered for an hour with the lid on, and then strained.
The third and fourth batches of fibre were simmered for an hour before being dyed. The third batch was simmered in water alone; the fourth batch was simmered in the salt mordant.
All were then simmered in their own respective stainless steel pots with strained dye, again with devoted utensils.
These were then set out to dry.
Tomorrow I will wash one piece of each lot and see if the dye remains fast or not. These will serve as a baseline for future dyeing, particularly in relationship to mordants such as alum (potassium aluminum sulfate KAl(SO4)2·12H2O).
