harvesting colour – the yellow of tansy
Since last September, a small bunch of Tansy (Tanacetum vulgare L.) has hung on the line in my kitchen. Now, with a small batch of alum-treated wool, I am able to see what colour will come from the dried and lifeless flowers.
~

To extract the dye, I crumbled the flowers and leaves and soaked them in water overnight. Then I added more water and brought them slowly to a boil in my big, well-marked dyepot (marked so I will not use it for food by mistake). After an hour’s boil, I let the dye cool and strained the liquid. The result was a clear, amber-yellow dye.

To dye the wool, I added water, immersed a shank of alum-treated wool and slowly brought the dye to a simmer – one hour and then the long process of cooling (I am realising that dyeing is more about waiting than doing!!!!!!!!!!!). The result is a green-yellow, almost exactly the colour shown for Tansy-dyed fibre in Jenny Dean’s book (Wild Color) !!! My photo is not clear because the drying line insists on vibrating but you can clearly see the colours – left to right – the brown of the lichen-dyed wool from a few days ago), the green-yellow of the Tansy-dyed wool and the tan of the undyed wool.

I wrote my poem to the heady yet sleepy smells of the Tansy boiling in its dye pot. I remembered the living Tansy, growing in the ditch last summer, each flower cluster hiding a sleepy bumblebee that had to be shaken from its resting. I was also reminded in my reading that Tansy was used so often at funerals in New England in the 19th century that people associated its smell with death.

Bitter Buttons hover in the dye pot
simmering on the kitchen stove
drowsy scent of camomile
camphor and rosemary
liquid amber, saffron sallow
jaundiced pale of Tansy
reclines in the roadside ditch
each flat-topped cluster
hibernaculum
for a furred and yellow
unconcerned
and mellow
bumblebee

harvesting colour – onion skin yellow
About a month ago, I stuffed an old white cotton shirt into a pickle jar with onion skins and cider vinegar (https://nichepoetryandprose.wordpress.com/2014/02/21/harvesting-colour-onion-skins-in-a-pickle-jar/). It was all I could do not to open the jar early to see how everything was progressing, but I was patient. On Friday, I opened the jar to see the results!

and my ‘new’ shirt hanging on the line to dry!

I am so pleased with the results. The yellows are bright and an old shirt is wearable again. The dried cloth is soft and smells clean and fresh. And, most important, I have another poem to add to my growing collection.

harvesting colour – the chemistry of colour
I have done a lot of reading this week, mostly to brush up on some basic chemistry in preparation for my project on using plant dyes.
~
It took me a couple of years in university to discover that chemistry was not my forté. I loved the mathematics of first year inorganic chemistry but I met my match with organic chemistry in my second year. I came to the conclusion that chess, music theory and organic chemistry have something in common … Jane cannot win a chess match against a cat. Jane cannot transpose music. And Jane cannot figure out elimination and substitution reactions in organic chemistry. I did try.
~
In spite of my theoretical difficulties, I loved the labs in chemistry. Creating little quantities of limonene and caffeine and aspirin was fun. And I loved the visuals of the chemistry lab – the colours of the various chemicals, the architecture of the glassware and the various drips and sizzles and, occasionally, puffs of smoke.
~
My first introduction to chemistry lab was a simple titration demonstration, showing a way to use the colour of an indicator to determine an unknown concentration. It seemed magic as I swirled the flask and watched for the solution to change its colour from clear to pink. I saw the parallels to botany right away. Today, I never look at a shrub of Hydrangea without thinking about the connection between the colour of the flowers and the acidity of the soil. Alkaline soils promote pink flowers. Increased acidity makes more aluminum available to the plant and the flowers turn blue as the aluminum associates with the plant pigment anthocyanin. These are the kinds of interactions I expect to see in my dyeing projects.
~
And so, here is my first offering of poetry in the theme of ‘harvesting colour’. It is not about dyeing fabric, but explores the idea of colour change as a metaphor for trying to understand human emotion.
~

titration
– to determine the concentration of an unknown solution, we watch for change

all summer she sits, the sag of a meniscus
on the stair of the veranda, tucked,
at the start-point of the burette,
into stems of hydrangea
~
mopheads droop and rain adjusts
the soil, basic to acidic, drop by drop
pink petals turn violet
first titration always an estimate
~
as the corymb favours blue, we realise –
basic words and helpful anecdotes will not be
enough, the situation is complex, not merely a matter
of pH, but the interaction, aluminum with anthocyanin
~
titration demands a practiced hand, a careful
eye to mark the end-point when colour prevails
and makes sad chemistry, on the last day of August
when hydrangea succumbs to blue

harvesting colour – gathering more materials
As I get ready for my first experiences with dyeing, I have thought about the materials I will be using. I don’t want to get too complicated and sabotage my real aim, the poetry I will write. I will try to keep it simple and generate lots of fuel for my writing.
Textile fibre: As I explained in my previous post on ‘harvesting colour’, I will use both plant (three old cotton shirts) and animal fibres (unspun wool and silk fabric).
Source water: I will be using our well water – slightly acidic and high in several minerals. Our water is so acid, it reacts with the copper piping in our house to stain all the drains in our house a copper sulphate blue. I know that the acidity of the source water influences the colour outcome. For some of the plant dyes I will use (for example madder), I will want to adjust the water acidity to get a full range of possible colours.
during our problems with our pump and well in 2013, we missed our tasty well water
~
Utensils: Last fall I bought myself a large stainless steel pot for my dyeing projects since I know it is important to keep my dying utensils separate from our cookware. I also have my Mother-in-law’s copper teapot if I want to add some ‘copper kettle’ to my dye projects (copper is a mordant, an addition that helps keep textiles colourfast).
~

~
Plant material: Even in winter, I have access to many plant materials for dying. I have various flower petals and other plant material from my various botanizing adventures. The drying line in my kitchen has a bouquet of tansy gathered last fall and a net bag of onion peelings I have collected since Christmas. I have acorns collected last fall and, outside, access to the bark of various trees, including birch (I am anxious to try this since I understand birch bark can dye in hues of red). In my freezer, I have frozen berries, including a tub of red currents picked by my Mom over ten years ago – I plan to use her berries to dye material for my weaving, after I have gained a little experience. As for in-season plants, I know my husband is looking forward to being dragged all over the countryside in search of various kinds of plants (he was a very helpful participant in my ‘growing and gathering’ project.

For next Friday’s ‘harvesting colour’ post, I’ll talk a little about mordants and colour modifiers and I think I’ll post my first poem in the series!

harvesting colour – onion skins in a pickle jar
According to India Flint (Eco Colour: Botanical Dyes for Beautiful Textiles, Interweave Press, 2010) the principal ingredient in any natural dyeing project is time (and patience). Now, while I am still getting organized, I have decided to begin with a simple project that can take all the time it needs.
I have chosen a cotton shirt for this project. I wore it for a couple of years and loved its iridescent buttons, rows of ruffles and embroidered details. Then it became stained and I put it away.
~

~
Today, I scattered the onion skins I have saved across its surface – some from Yellow Onions and some from Red Onions. As I worked, I sprayed apple cider vinegar to wet the fabric. Then I rolled it up tightly and poked it into a big pickle jar. For at least a month, I will leave the jar to sit on my window sill and cook in the sun. If it starts to grow mold, I am going to stuff it in the freezer. The biggest challenge was getting all that material to fit in the jar!

all I can say is ‘yum’ …

If you hear of a smelly house for sale in rural New Brunswick, you will know something went terribly wrong. I will show you the results, as well as the poem this generates, in about a month’s time …

harvesting colour – the formula for colour
My first effort towards my project is to understand what materials I will need. From my early reading, I have learned the end colour for any project using natural dyes is much more than just adding plant material to water. A final colour is the result of so many factors.
~
My simple formula for this complex symphony is:
final colour = source water + utensils + plant material (dyestuff) + mordent + colour modifier + textile fibre
~
No doubt, I will discover I have omitted some important element.
~
In my next posts, I will consider each of these elements and talk about the specific items I intend to use.
~
For example, I will need some textile fibre to dye. My intention is to dye small amounts of material for use in various weaving projects. In my weaving, I use both thread and strips of textiles.
At this early stage, I have three materials I want to dye. I have a small quantity of unspun fleece obtained a couple of years ago during our trip to Upper Canada Village in Ontario. I also have three old cotton shirts – I loved to wear these before they became stained – perhaps I will wear them again, repurposed in rainbow colour! And I have just purchased a meter of white silk (at $37 per meter, it is a splurge!). I will have to do some preparatory cleaning to each of these materials before I use them in my dyeing projects.
~
some materials for dyeing … a meter of silk, three shirts, and a bundle of unspun wool … the shirts have already seen their share of accidental dyeing !!!
~
Behind the scenes, I am finding poetic inspiration as I learn this craft of dyeing. Eventually I will be brave enough to show my poems to you.

harvesting colour – a reference library
To begin my poetry project ‘harvesting colour’, I have created a small reference library. I will keep my library by my desk in the loft I use as my studio. I wrote most of the poems for my ‘growing and gathering’ manuscript there.
on my desk
To decide what books to order, I followed some suggestions made by Pia, an experienced dyer (follow her dyeing adventures at Colour Cottage – www.colourcottage.wordpress.com).
~
I started with three books:
Rita Buchanan, 1999, A Dyer’s Garden (Dover Publications)
Jenny Dean, 2010, Wild Color: The Complete Guide to Making and Using Natural Dyes (Watson-Guptill Publications)
India Flint, 2010, Eco Colour: Botanical Dyes for Beautiful Textiles (Interweave Press)
~
I am sure I will be adding others as my project goes on, but for now these books have lots of great advice for a beginning dyer. Along with these books, I have my entire library of illustrated botanical guides, including floras of New Brunswick, Nova Scotia and North America to help me identify the plants I will need.
~
my growing dyers library
~
Roaming through these books as an ‘armchair dyer’ reminds me of the thrill of looking over seed catalogues while the snows of winter are falling.
Although I have not read any of these books in their entirety, I will give you a brief description of each:
~
Rita Buchanan, 1999, A Dyer’s Garden (Dover Publications)
~
Rita Buchanan’s A Dyer’s Garden is a straightforward guide to using plants for various cottage craft purposes. The guide includes information on using plants as dyes, as well as for stuffing, soap-making and a source of fragrance. The chapter on dyes provides a step by step method, as well as an in-depth description of various plants useable for dyes. I love the black and white line drawings for some of these plants. The book includes practical information throughout on growing these plants and on the history of their use.
~
Jenny Dean, 2010, Wild Color: The Complete Guide to Making and Using Natural Dyes (Watson-Guptill Publications)
~
Jenny Dean’s book, Wild Color, is a riot of colour. Easy to flip through, it has detailed sections on various stages of the dyeing process. A useful feature for me will be her illustrated guide to some common plants used as dyestuffs. I particularly like her colour charts of results obtained with various dyestuff, mordants and modifiers. She also includes some background material on the history of dyers and dyeing.
~
India Flint, 2010, Eco Colour: Botanical Dyes for Beautiful Textiles (Interweave Press)
~
Eco Colour by India Flint is a well-illustrated book, full of photos of the author’s work with plants and fabrics. You can tell she has been there every step of the way – included in the photos are her handwritten notes. She describes well the process of dyeing and provides practical information. She also includes lots of examples of colour transfers (eco prints) – leaves are applied directly to the cloth to make colour prints. The book includes an extensive list of plants sorted by the colours they produce.
~
I can hardly wait to thoroughly read these three books. Besides looking for a step by step approach, I will be on the hunt for words from the dyer’s vocabulary to include in my poems.
~
Another resource I will use for my project will be the Internet. I read the blogs of a few dyers regularly, to learn something from their experiences, to get their advice and to better know these people who turn their appreciation of colour in nature into capturing colour. I’m sure you will enjoy these blogs about dyeing and fabrics as much as I do:

~
Now that I have my reference library underway, I am gathering ideas about what I will need to begin my project. My next post will show you some of the items I will be using.
