A Collection

To coincide with the Fibre Arts@Ballarat workshops this year there will be an exhibition of tutor's work entitled A Collection at The Lost Ones Gallery in Camp Street Ballarat from 16 March to 3rd April.
View of exhibition at the Lost Ones Gallery
This exhibition has been curated by Tara Poole from RIIS Strategic Consulting and will provide a wonderful snapshot of the talent and creativity of the tutors at this year's workshops.  It will give the general public an idea of what goes on at the Ballarat Grammar School when the boarders are away during the Easter holidays, and hopefully inspire some of them to try the workshops for themselves.
I am so looking forward to this year's class, to meet up with hundreds of like-minded fibre enthusiasts and to have a break from cooking and cleaning (and moving house) for a week. It is always inspiring to meet the other tutors, to go for daily walks around the lake, check out the botanic gardens and spend a whole week just exploring natural dyes and mordants in a well-organised and extremely fun working holiday.

Hand/Eye Magazine

























I have been a follower of the Hand/Eye magazine for sometime so it was a great surprise to get an email from Jessica Hemmings to say that my chapter for her book Cultural Threads had been featured in the latest online edition. If you haven't read the book yet, you can see my full article here:

Asian Textile Studies

A few weeks ago I was contacted by two asian textiles collectors, David and Sue Richardson from the UK who have started their own website, Asian Textile Studies. They had found my blog over the internet and wanted to know if they could use some of the photos I had taken of my cloths that I had dyed whilst I was artist in residence at Rimbun Dahan in 2013. Specifically, they were after brown dyes for their last chapter on the website.

Their email to me came just in time - I have been working hard in the studio to finish off a number of naturally dyed textiles for an upcoming group exhibition  about my time in Malaysia, entitled Here & There. So of course I have been cutting up these larger pieces of cloth to use in my exhibition.  If the email had come any later I would not have had anything to give them for their website!

Here & There  will be shown at the Belconnen Art Centre in late April, so I will write a more descriptive post about the exhibition closer to the time.

More photos of my work can be found on the Asian Textile Studies website here.

Migrated

Migrations:  Image: Jessica Hemmings
Yesterday was the final showing of the Migrations exhibition at the Australian Design Centre in Sydney.  This exhibition was curated by Professor Jessica Hemmings, author of the book my work was featured in last year, Cultural Threads.

I hope you got to see it as there were a few works in the exhibition that were made by artists not featured in the book, such as the printed textiles of Toril Johannessen from her Unlearning Optical Illusions series inspired by wax resist cloths, and Godfried Donkor, whose video work explores his mother's collection of wax-resist prints and the naming of them. I was fortunate to meet both Toril and Godfried in London last year when I attended  and spoke at the book launch and one day symposium.

Indigo BLUES!

I held a really enjoyable workshop at the end of January at Timeless Textiles in Newcastle, followed by an equally enjoyable Introduction to Mordant Printing workshop the following weekend for ATASDA.  In between the two workshops I was also moving house after 17 years, so no prizes for guessing why I haven't posted anything until now....!
The topic of my post today is one I have been itching to write since my Indigo workshop, and one I know my students will find beneficial.  On the third day of the workshop our indigo vat, which had been behaving perfectly, decided to go sad on us and refused to cooperate.  Luckily we were all at a stage where we were getting ready to start packing up from an intensive 3 days, but it was still annoying and perplexing for me as to why it happened all of a sudden...hence the title...Indigo Blues...I was sad that all my tricks would not liven up the vat again.
Around the same time I had an email from one of my past students from last year saying the same thing had happened to her and what could I suggest the problems might be and how could she remedy it.  So here goes:
The vat we were using was an organic henna vat, I used powdered Lawsonia inermis (henna) with calcium hydroxide (builders lime) and natural indigo in the 1-2-3 ratio I was taught by Catharine Ellis. 
The vat was kept warm at night by standing it in an electric urn filled with water and then covered with plastic and blankets. The air temperature in the day was between 25-30C. In the mornings I would turn the urn back on until the vat got to dyeing temperature, I would stir it, wait at least half an hour and then take the pH and temperature before testing a small piece of white cotton before we started the day's dyeing.
So far so good.
After the vat failed we added the remainder of the 'mother vat' to it in order to spark it back up again but as this did not happen,  I realised that if that did not remedy it then I would have to monitor it more closely, as I knew that lack of indigo was not the problem, and the addition of more indigo would not produce darker results, I would just be wasting indigo. I purchased a green garbage bin with a lid from the hardware store that fit my whole vat inside it and carefully transported it back in my van to my studio in Canberra.
I put the vat outside in the sun to warm up, then I took a sample reading from the vat, took its temperature and pH.


Poor sad looking indigo vat, the flower is small and bubbles are white and pale.
The vat was not getting up to temperature, so I took it inside and warmed it in the bain marie urn again. Another stir, another test sample but still the vat refused to work.  At the end of the day I added 20g of henna powder cooked in 500ml of boiling water, then stirred it and left it over night. Here are the test samples from this first day:
The flower is in better shape and shows tinges of blue bubbles

Very pale results
 The following day I put the vat outside in the sun again and when the sun moved I bought it inside and heated it in the bain marie and took another sample.
Slightly better results

During this time I had been searching in vain to buy Fructose powder which is a more immediate form of sugar/carbohydrate for the vat (as opposed to henna).  Fructose is very difficult to find in Australia and especially in Canberra and I had a very frustrating time visiting websites and supermarkets, healthfood stores etc.  Henna and fructose both feed the vat to keep the reduction going.  Fructose is like a sprinter - it works quickly but burns up fast, whereas henna is like a marathon runner, it takes its time but lasts the distance, and the two substances can both be used as reduction agents in the organic indigo vat.
I then had to go to Sydney for a couple of days to teach a workshop, so the vat was again left to it's own devices. Whilst I was in Sydney, however, I mentioned my fructose dilemma to a friend and fellow-dyer, Sylvia Riley, who owns Silksational, the one-stop shop for fibres, fabrics and dyes.....of course she had fructose powder! What a lifesaver!!
On my return from Sydney I added 40g fructose to my vat, gave it a stir, left it outside in the sun and tested pH iand temperature. The pH was 12, but the dipped colour had gone back to pale again.All my dipped samples were for 2 minutes each in the vat, at least 2 mins oxidising.  I another variable I was monitoring, but which is hard to photograph for the blog, was the colour and clarity of the vat below the surface.  It should be clear and yellow/green when it is ready to dye with.  Mine was murky green and cloudy.
The bubbles were blue but there was also a blue halo around them.

However, the test sample is still very pale.

Moving house and life got in the way, so the next opportunity to tend to the vat came on 15th Feb, a full 2 weeks after the workshop in Newcastle.  I felt guilty for not attending to it every day, but knew if I kept at it it would come good, and that throwing the vat out was not an option because I knew there was indigo in there to use, and I hate wasting materials and money!
I added another 60g fructose to the vat, stirred and rested it. The next day (16th) I came to the studio, stirred it and tested it after half an hour.
Three tests in one day showing gradual recovery of vat
My first test at 2.30pm showed a small response from the vat - the colour was much darker than the previous day and so I continued to monitor.  At 3pm I added another 50g fructose, stirred and rested the vat then took a sample (#2).  I took the pH reading, and to my suprise the pH had dropped to around 8 - far too low for dyeing cotton, but actually predictable given that I had only been feeding the vat with either fructose or henna since it failed a couple of weeks ago. I now needed to re-balance the vat with lime.

16/2 pH tests at 3.30pm (left) and 4.30pm (right)
At 3.45pm I sprinkled a tablespoon of lime onto the surface of my vat...this was immediately sucked down into the vat, which I knew was a sign that it was time rebalance with more lime.  If the lime just sat on the surface of the vat then it would not need any lime. Over the course of a few minutes I sprinkled approximately 15g of lime onto the vat and watched it disappear into the murky depths below.  I took a video of this with my ipad and when I learn how to upload it onto my blog I will! As you can see from the samples and pH tests above, I stirred the vat, let it rest and then took a sample again at 4.30pm.  The colour had started to come back! I was on track.  I knew there was approximately only a half-strength indigo left in the vat because I had been monitoring it and the quantities I had used and the amount of fabric we had dyed in the workshop, so I realised I wouldn't get a very dark blue - that would be unreasonable - but I did know that there was indigo left in the vat and it was just a matter of working away at it to get it out again.

17/2 The Flower was looking good and the surface started to get that reflective
'oily' look on the top with a skin starting to form in the afternoon.
Final test from recovered vat.
I did a final test for pH, temperature and then took another sample. This was a beautiful mid-blue in keeping with the amount of indigo I think was left in the vat (40%).

The moral of this story is that your indigo vat may not be completely exhausted even though it is not giving you any colour - it may just need monitoring and the addition of reduction agent (henna, or fructose) and/or lime in order for the vat to recover.  If you throw it out you are wasting precious indigo.

Hopefully this post will give you some insights into how your own vat can be monitored and recovered.  Obviously if you dye a lot of fabric the indigo WILL eventually run out, however I had kept tabs on this and knew that there was indigo left in the vat...somewhere....!

 Here are two examples of  resist-paste indigo fabrics I did during the workshop I taught, intentionally alternating paste resist and indigo dipping to achieve the many shades of blue.

I am forever grateful to Catharine Ellis and Joy Boutrup for teaching me this organic indigo vat, because I had learnt how to dye with synthetic indigo about 25 years ago and was not a big fan of all the chemicals etc.  Having indigo on hand now really supports my natural dye practice, so that I can obtain more colours naturally as well as improve the fastness of them.

Hope this has helped you with your indigo vat problems and happy indigo dyeing for the future!
My website has an events page where I list my upcoming workshops, but please feel free to contact me directly at info@julieryder.com.au if you would like further information or you would like to book me to teach a specific workshop for your group. You can also comment directly on this post below and I would appreciate your feedback.

Organic Indigo Workshop

Julie Ryder Organic Indigo Workshop samples
Last chance to book in for the three-day organic indigo workshop I am running this coming weekend at Timeless Textiles in Newcastle.
This workshop will explore the many aspects of shibori in order to resist-dye with indigo – clamping (itajime), stitching (nui), pole-wrapping (arashi) and many other methods. The stunning indigo blue that is produced will magically develop before your eyes. We will also discover the magic of indigo resist paste printing and dyeing in the same vat, to produce stunning blue and white prints.

Last chance to visit YELLOW

YELLOW exhibition at barometer Gallery
I have been so quiet on the blog front since the end of December that you could be forgiven for thinking that perhaps I had snuck away to some remote island, spending my days sleeping, reading and eating.....Well, that sounds perfect but unfortunately is far removed from the truth.
Since December I have been up to Sydney for a week where YELLOW has been installed - and it's the last day today! Barbara Rogers, Catherine Rogers and myself have all responded to theme of yellow for our annual Christmas show ( in the past it has been Blue, Red, White, Green....).  You can see two of my three pollen prints on the right hand wall. Catherine has hung some great digital prints on paper as well as some photos and Barbara has produced some amazing textiles.
I have also been planning my upcoming two workshops on Indigo dyeing with resist paste and shibori coming up at Timeless Textiles next weekend. I will do a separate post on this tomorrow, so for now ...hurry on down to Barometer before the show shuts!
