Silk

In writing my bibliography I was startled to discover I had not written about a very, very good book that I discovered last year on silk. I did write on "Silk: what every weaver should know", with details of other books, so I must have purchased this particular book after I'd published that entry. I also wrote last May on the local history of silk spinning and weaving.

I was hunting high and low for information about silk as I wanted to know all about silk production so I could understand the yarns available, and also because I like to see the things in my life as part of a bigger picture. A yarn has more meaning if I know and understand: where does it start and where will it end?

Yes, I am turning philosophical now - I think it is important to know because we all make decisions that effect other people, and the sequence - what we acquire, how we use it, where it goes when we are finished - is a process that contributes to shape the world we live in.

I was also motivated by having bought some yarn of a quality that I thought was rather poor for expensive silk. More exploration showed I had bought relatively cheap, maybe this was part of the problem. It was full of knots and all wispy at the edges. I queried with the seller whether it really was thrown silk, as claimed, they told me they had it checked by an expert and and that it was (but there was no written report, so I don't know quite what the expert said)... and I thought thrown silk was made from long continuous filament and shouldn't have wispy ends protruding. So I hunted high and low on the internet to learn more.

This book which I found is about the big picture, it is:
Global Silk Industry: A complete source book, by Rajat K Datta and Mahesh Nanavaty, published by Universal Publishers, USA, 2005, ISBN 1-58112-493.
I found and bought it via Amazon.com, it was inexpensive - at a time when the dollar-pound exchange rate was more favourable!

The authors are well qualified. Rajat K Datta is a retired director of International and National Sericulture Research Institutes in India (author of 300 scientific and technical papers) and Mahesh Nanavaty has worked for over 30 years in the silk industry, in the USA and India. The foreword is written by Xavier Gavyn Lavergne, as Secretary General of the International Silk Association.

As regards the content of the book, the preface has this neat summary
"Here are gathered, indeed, the main information and anaylsis regarding the history of production and trade of this exceptional fiber, from the origins of silk to the 21st century, covering the important changes in the silk scenario notably in the course of the 20th centruy, which explain today's situation and enlighten the future."

So we have history, we have a chapter looking at silk in relation to other fibres, an overview of the global silk industry today, and several chapters on silk production. There are reports on current and developing technology, and on the uses and market / marketing of silk.

However, this is not a heavyweight textbook, it is a paperback, 352 pages plus appendices and I found it a good read. Not only that, it filled in many gaps for me, I'm happier now that I understand how to find the quality of silk, and type of yarns, I want to buy, and where my use of silk fits in to the big picture.

At the year's end

I've been working on a Bibliography for my blog, for which you'll find a link in the sidebar.

This has entailed reading back through all my blog posts and running back and forth to the book shelves to check details. It's a task I was indirectly prompted to do by Leigh - who asked several months ago if I would think about joining up to the Library Thing. I had time this week to look at Leigh's books on the Library Thing (click on the tag on her blog page). She's listed 133 books - that's a lot of work, well done Leigh! I realised I already had lots of book details in my blog pages, and for some of them I've written reviews, or some information about why they interest me, so the "Bibliography" link seemed a sensible way way for me to organise information about my library.

I spent a few days trying to work out how to make nice page tags, as I've seen Leigh and several other bloggers using, but after three days of reading my book on html and css and other people's source code I'd had enough and took a short cut. The Bibliography is made in a blog post that I gave a posting date to that pre-dates my first blog entry, and then it was easy to link to this page and easy to find it for editing.

One of the interesting things I discovered in the process of this task was which books I have written about, and which I have omitted. Ahh! Now I am well set to write about the rest of the books on my shelf, so you can expect more reviews in 2009. There's only 62 books in my bibliography, far more than that on the shelf, and I ordered another 4 weaving books just yesterday (!)

Something else I did this week was to read back through all my posts for 2008. Not because I particularly like to dwell on history, but because I've had flu for two weeks and not felt much like doing anything else! I was interested to re-discover how much I have done, and learnt, in the past 12 months. This has to be another good reason for keeping a blog. Sometimes I feel very frustrated at my lack of progress, like many hobby weavers the day job(s) seem a great obstacle to my ambitions.

Good news for 2009 is I have (as of 20th December) cut the day jobs down to just one (a year ago I had three jobs, cut in July to two) and my going out to work week is down from six days to four. Hurray! Will this mean more weaving time? I hope so.

Colours - theories and practice

I've been meaning to get back to writing about colour, and hanging up multi-coloured Christmas lights in our front window on the evening of the winter solstice brought back many thoughts about colour.

There is a fashion for blue Christmas lights. A nearby town has a magnificent tall Christmas tree, it passes muster in daylight, but at night the sole decoration tiny blue lights leave it looking dingy, dull and mean. Not what I call Christmassy, no spirit of joy, of giving and sharing. It looks like they couldn't really be bothered (who are they? the councillors? some official with a small budget?). I don't name the town - it's local and I'm ashamed of it.

There is no doubt colour and colour choices are important. Everyone knows their own likes and dislikes for different colours in different places. I realised recently, when discussing colour samplers, that I have been building my own ideas about colour interactions steadily over many years, and I take what I know for granted.

Because my understanding of colour is in patterns in my mind, and because colour is a complex subject, I found to my surprise that I lacked words and phrases for talking about my views on colour.

So what could I say to someone else about colour? This is where I feel comfortable:
  • I can talk a bit about rainbows and the spectrum colours when white light is split with a glass prism.
  • I know the terms "warm" and "cool" and associate them with the colours of hot things and colours of cold things.
  • I know that colour temperature relates to how "white" a light is and gives an indication of a tint towards yellow or blue.
  • I know that colours look different in different lights.
  • I know that in my box of drawing pastels, where each colour is available in 5 tints, no. 3 is pure pigment, 2 and 1 have white added and 4 and 5 have black added.
  • I know that pigments in paints and dyes interact with each other differently to mixing colours of light.

That seems like a reasonable list now I write it down. But I didn't seem to be able to explain to other people how I choose colours and how I predict what combinations I decide will work together, and I was shaky on the details of the above - like how to explain why pigments behave as they do, what light temperature is about, what happens with different colours under different lights.

This set me off in two directions however, both seemed to involve buying more books! (I find it hard to ignore any excuse for another book.) I read a lot, learnt a lot, got a bit confused and then ended up about where I started!

I learnt that colour theory in relation to making colour choices seemed to take off at the end of the 19th century, and that modern "colour theory" crystallized with the Bauhaus movement and teaching. Since early 20th century, "colour theory" has been passed on often with little of the context or background for the theories. Some modern colour theory books present us only with a set rules and no reasoning. Personally I react against rules without reasons. I was born to ask "why" and remember getting into trouble on many occasions in my childhood for insisting on having "why" answered, and refusing to obey rules that had no whys!

Hunting through bibliographies and references to ever older texts on colour brought me to the purchase of two lovely old books.

Colour Matching on Textiles: a manual intended for the use of dyers, calico printers, and textile colour chemists, by David Paterson, published by Scott, Greenwood & Co., London, 1901,

and

Colour in Woven Design: being a treatise on the science and technology of textile colouring, by Roberts Beaumont, published by Whittaker & Co. of London and New York in 1912.

The first is a lovely old text book, written for those in the trades named in the title, and begins at the beginning - by looking at how the human eye perceives colours with full description of the parts of the eye and how the eye works. Chapter 1 is all about this, chapter 2 is about the qualities of different natural daylight sources (artificial light sources are not mentioned until chapter 8) Chap. 3 is on hues and purity of colour, other chapters are specifically about dye matching for textiles.

This book introduced the name of a man who seems to have been one of the first to try and develop rules about how different colours interact when used together: the French chemist M. E Chevreul.

Principles of the Harmony and Contrast of Colours and Their Application to the Arts, M.E. Chevreul, 2nd edition pub. 1855, Longman & Brown.
(Fairly recently republished in the U.S.)

It was Monsieur Chevreul, a chemist in charge of the dyeing department of the famous Gobelins tapestry workshops in France who seems to have been the first to examine why, in the words of David Patterson "a colour may appear rich and saturated in one pattern, and yet appear dull and wanting in vigour when put into another pattern with a different scheme of colouring". This seems to be the root of our modern colour wheel organised theory. I tracked down an early edition of this book at a second hand book shop. It was priced at £50 and not in good condition, so I did not buy, but I was interested to hold a copy of this book and see what it contained and how it was organised. M. Chevreul developed his theories of colour behaviour based on close examination, and it seems asking everyone who came near him to take a look at different colour combinations and say what they thought (reminded me of my optician asking which colour is brighter now, red or green, and now...?) His book ends with chapters applying his ideas to different arts, e.g. a chapter on weaving giving recommendations for ways to use colours in stripes in order to produce pleasing results.

By the time Roberts Beaumont writes in 1912 he describes different well known and recognised theories of colour, and this book is very much a practical handbook for textile designers. He deals with Theories of Colour, Attributes of Colour, Contrast and Harmony in the first three chapters, then following "Colour Standardisation" he is on to chapters about weaving cloth with stripes, checks, compound colourings, spotted effects, etc.

This is a similar approach to that of:
William Watson, in Textile Design and Colour, pub. Longmans, Green & Co. Ltd, my 6th edition dated 1954.

Meanwhile, another line in development of colour theories is beginning as Johannes Itten, born in 1888, started studied painting and colour formally in 1913. He joined the famous Bauhaus as a master and was there 1919 to 1923, developing a course on form and colour. Itten's major contribution to colour theory was:
The Art of Colour, by Johannes Itten, pub. 1944
I have before me now (from the local library) the abbreviated version of this work (condensed text of the above, without the original colour plates):
The Elements of Color, edited and with a forword and evaluation by Faber Birren, published by Van Nostrand Reinhold Company, 1970.
Reading this book, about complimentary colours, contrasts etc. I find that more recent books on colour theory seem to add nothing to what is here. If you want to study colour theory, this is probably about the best book. If you want to play with colours and see how they behave for yourself, then I think it is worthwhile also having:
Interaction of Color, by Josef Albers, published by Yale University Press, 1963
which provides a course to work through to study and learn about colour interactions by experience.
(I was able to get a copy of this through my local library also).

The only more recent book I think well worth a mention is:
Dyeing to Knit, by Elaine Eskesen, published by Down East Books, 2005, ISBN 0-89272-667-9 and ISBN 978-089272-667

Why don't I mention others? Because certain other authors use the colour wheel based theories as rigid rules without applying judgement and common sense and produce a lot of combinations which to me look like mud, or shades of grey. One particular author gives no bibliography and no history so it is as if she made it all up by herself. I mention no names, yes, she is famous and everyone else likes her and will jump up and protest at my words if I mention her name. So I don't. I just say, use your own eyes, your own common sense, decide for yourself and don't follow blindly.

Now I like Elaine Eskesen because she attributes the ideas in modern colour theory to their originators, quotes Chevereul, includes Ittens and the Faber Birren Elements of Colour in her bibliography so you know where her ideas come from. Then she adds something of her own, she explains ideas that have evolved through working for many years in using dyes and using dyed yarns. I like a section in the book where she has given some very different yarns she has dyed to famous knitters and they have knitted something and then comment on the yarn and the colours.

So should you go out and buy any of these? That's up to you, I'd say borrow them from a library or a friend, read them through, then move on. I think that understand colour theory ought to be at background level when you are designing. I would compare studying colour theory together with learning scales as part of learning to play a musical instrument, useful, but not an end in itself.

I like the way people put colours together by looking at a favourite picture, and saying "here are some colours I like to see together", or collecting a little pile of coloured objects, or coloured pieces of paper, cloth or yarns, or a coloured sketch of something they have seen, and then saying "I will use these colours".

Also, I like to read about Bonnie Tarses' amazing colour combinations, which always seem to work (she talks about it in WeaveCast episode 9) I think part of the secret of this is good quality yarn colours.

Oh, I nearly forgot to mention, Bernat Klein developed a theory of his own that the colours that suit a person are the colours to be found in the irises of their eyes. An interesting idea. I wonder, does it work for you, reader? Comments welcome! I neither strongly agree nor disagree with this, but I would say that for a person with chestnut to strawberry-blonde type red hair, as I have had (now fading) with very blue eyes, this doesn't quite work. My best colours are greens and autumn shades, but then I seem to recall he said somewhere that the red-haired are an exception to the rule.

Season's greetings to all.
