Review of a new Dye Book


The Complete Guide to Natural Dyeing
Techniques and Recipes for dyeing fabrics,yarns and fibres at home
Eva Lambert and Tracy Kendal
Published by Search Press ISBN 1-84448-527-7

When Amazon first contacted me to tell me there was a new dye book about to be published my first reaction was “ Oh no not another one” as this will be the third in so many years. However not able to resist a dye book I have now added it to my growing collection. The first impact is colour-loads of glorious colour right from the word go -as the very first pages are pictures of samples of dyed fabrics with the page number of where to find how to dye that colour. In the first chapter there are photo's of quite outstanding fabrics by artists such as Isabella Whitworth whose fabulous scarves are shown and Kimberly Baxter Packwood's compost dyed fabrics. These would inspire anybody to want to try natural dyeing.

The book is very easy to use, clearly laid out and the instructions are good. I love the addition of colour theory, the emphasis on the importance of record keeping as well as the really excellent introduction to tie dying, batik and other resist techniques. The dye recipes are good too although I found myself wondering if you really could simmer water at 60 degrees C . Criticisms? Well there are more than a few- it seems odd to me that a book describing itself as the complete guide to natural dyeing should have nothing in it about the extracts of natural dyes. For example Eva Lambert describes at some length how to random dye yarn in different dye pots a laborious process of tying, un-tying dipping into different dye pots that led me more than ten years ago to greet the appearance of the extract dyes , which allow you to hand paint fibres, with enthusiasm. As I read through the book I also went backwards and forwards in puzzlement as nowhere could I find a difference in mordant recipes for protein and cellulose fibres whether as yarn or as cloth. This I don't understand as alum bonds to protein fibres in an acid environment, to cellulose in an alkaline. The chapters on indigo dyeing is comprehensive,and the picture of all the different fabrics and the different way they have take up indigo quite superb, but the chemistry of indigo dyeing is not fully understood. I am intrigued by the addition of salt to an indigo vat-something Sandberg also does- but I do not like the heavy use of caustic soda( sodium hydroxide) in the indigo vats throughout.

I found the lack of a bibliography more than a little surprising and while I really appreciated the down to earth unfussed approach I also found having the health and safety chapter at the end disconcerting. That said the vibrancy of the colours and the clarity of the instructions makes this book very definitely the best of the new books published in recent years and will start many an eager dyer off on a journey of discovery , inspire others to experiment and me … I am off to try putting salt in an indigo vat something I have never got round to trying.

Natural Dyes by Judy Hardman and Sally Pinhey

Posted by Helen
Just before I went off to the Woolfest I ordered this book-daft of me because I probably could have got it there. It has just been published so on the principal that a dyer can't have too many books I got it as soon as I saw it mentioned on another blog.

Judy Hardman writes about the dyeing while Sally Pinhey produced the beautiful botanical illustrations. Judy chose plants (I counted 59) that you could either grow in the garden or can find easily growing wild ranging from Agrimony to Yew. The book is similar in lay out to Margaret and John Cannon's " Plants Dye Plants and Dyeing" published in association with Kew Gardens and illustrated by Greta Dalby Quenet. In both cases the text is on the left hand side while the botanical illustrations are on the right. However Judy Hardman has also added some photographs to her text and pictures of some beautiful fair isle knitting scattered throughout.
The plants are listed alphabetically according to their English name with the Latin name underneath.
Judy then tells you a little about the use of the plant in previous times, some fascinating bits of ancient lore before telling you how to dye with the plant. At the bottom of the page are samples of dyed wool using the traditional four mordants: alum,copper, tin and chrome.
Judy's explanation of preparation are concise and mostly easy to follow although I found her instructions on cotton scouring and mordanting a little confusing . She is also very clear on the risks attached to using copper and chrome although I could not find any mention of the fact that chrome-potassium bichromate is a carcinogen. I was disturbed to find that on page 20 on the section on scouring cotton she says to use 24% WOF (weight of fibres) washing soda/caustic soda,the first of course is sodium carbonate the second sodium hydroxide and a powerful alkali. It is possible that boiling cotton in 24% WOF of caustic soda would destroy the cotton. However I have corresponded with Judy and she say unfortunately the editing failed and this should have read washing soda/not caustic soda. There are one or two other editing errors-elsewhere she mentions 8%cream of tartar and7% Alum as a mordant (the figures have been reversed) but she tells me she has a page on her website listing all the errors and that can be found here at www.somborneshetlands.co.uk/errata.html
I disagreed quite fundamentally with her comment that that yarn dyed blue with woad or with Polygonum Tinctoria (now Persicaria Tinctoria) is likely to rub off on your hands as you knit because the indigotin is a contact dye. It may rub off but if it does it is because of faulty dyeing, a very common fault caused mostly by either over reduction or over heating of the vat. In this case the indigo white, the soluble form of indogitin, is too soluble and converts in the air too rapidly resulting in faulty bonding to the fibres. Here is link to Debbie Bamford blog on this very issue to prove my point!.

I was also a little baffled with her division of types of dyes into direct, mordant or substantive. Her definition of substantive dyes is that they are the vat dyes not as is normally defined dyes that will dye without an additional mordant. These dyes she appear to define as direct dyes.
What I like about the book is that Judy has plainly dyed with all the plants she mentions, and for example she is the first person I know who got colour from the roots of Iris Pseudocorus.
I love all the information about the plants, but I would have liked references to the primary sources and more about the dyes in the plants. However I like the fact she talks about solar dyeing, about dyeing for felting, and about lightfastness. She also has a large section at the back of the book devoted to a variety of layout for different types of dye garden including one for container gardens. I showed it to students attending a dyeing workshop on Saturday and they all were very enthusiastic about it especially two who are planning to have a dye garden.
It is a lovely book, a pleasure to have on my shelf and I was very glad, as I was about to chop meadowsweet for a solar bath while I had a glass of wine, to discover meadow sweet contained prussic acid so I deferred the chopping till after I had had my wine. Shame about the typos and the editing but it is rare to find a perfect book and this one will be a welcome addition onto a dyers shelf particularly for dyers interested in growing and gathering plants.
