Hi We have added a section of woad history to the woad website. It has been fascinating doing the research (and never ending!). If anybody would like to give...
Hi, Everyone My DD is putting together a website with her science fair project on woad in it. http://woad.ca In the last few days she has been taking pictures...
I saw "In Search of Lost Colour", the new documentary by Maiwa in Vancouver, Canada. Just released after their world debut at the Maiwa symposium last week. ...
Happy New Year Friends The list has been very quiet. What are everyone's woad plans for 2008? We have seed from Norway to trial this Spring, plus the two...
Hi Chris Very interesting reports from your yieds. If I understood correctly, you got the higher yields with Tewkesbury woad in the 'neglected' control? I am...
HI, Teresinha The neglected control did produce a higher weight of dried indigo pigment - about 1/3 rd more by weight than the well tended, manure fed woad...
Hi, all Teresinha suggested last summer that we may find a difference in colour or purity between the three varieties and the control woad that we grew. My DD...
Hi Chris The first the Chinese heard about woad giving blue was when I told them. Apparently they only use the roots. I suggested they look for a machine that...
Hi Chris This is very interesting (that different varieties produce different colours). What fibre did your DD used in the comparisons? So far I bought 3 kilos...
I think the different colours were different levels of impurities in the vats. Indirubin and indigo green, as well as indigo yellow are considered impurities...
Teresinha, did you manage to measure the indigo yields of Tewksbury and Bleu de lectoure separately in your allotment experiments last summer? If so did you...
When I dye with natural indian indigo the resulting textile rubs off blue when it comes into contact with human skin. This is supposed to be desireable and...
I double checked -- Bleu de Lectoure reports 1 ton of leaves to 2 kg. of dried indigo powder. (That would be 2grams of powder per 1kg. leaves). This is the...
Hi Chris I did not have enough plants this year to measure the yields, but hope to do so this year. Interesting to know that you need more than one plant to...
Hi Chris I've only ever knitted with woad dyed wool, and experienced no crocking or fingers turning blue. Teresinha ... From: Robin & Chris Dalziel To:...
i wandered if a winefilter (i posted a photo from a catalog of a home- make-wine-supplier) could be of any use to get the indigopowder? (www.brouwland.com nr....
Hi Mieke Sorry, could not find the photo. What is a wine filter? Is it like a coffee filter, made of paper? I tried all sorts for the filter, including polen...
Hi, Mieke At the University of Bristol they recommend a 100 micron filter. That would be a laboratory filter. I tried a milk filter, which is what I had on...
Hi, Teresinha, et als The Chinese woad has a more sensitive "vernal" period than Isatis tinctoria. I tried to grow it when we lived on the coast of BC, near...
That's good to hear. I think then that woad is more colourfast than indian indigo. I think this bears with something I read but I can't place it right now. ...
Hi Chinese woad : might cross with I. tinctoria. hope it does not bold for me. will let you know. Moving woad: my woad has a very large root system so it...
Hi Chris I mentioned earlier on in the website that woad was more fade resistant, but if I remember it correctly, Jenny insisted that there is not difference...
Hi, Teresinha My DD science fair project last year tested natural indigo (indigoferas tinctorum) for fastness with washing and light. There was fading only on...
Waste water after indigo extraction: I added 1 tsp. of thiourea dioxide to the waste water, brought it up to about 40C and let it sit for an hour. The water...
While cruising the web I came across this article about artisanal use of woad. http://www.craftrevival.org/voiceDetails.asp?Code=167 Interesting that woad is...
Hi, All What temperature do you extract your woad indigo at? And do you think you are getting all the available indigo? Do you add an acid to the extraction ...
Hi Chris I heat the water to 90C, add the leaves, which bring the temp down to about 80C and I leave the leaves at 80 for 10 minutes, then I cool down quickly....
Hi, Teresinha and others following this thread, Thank you for sending your results. Do you remember when you did your harvest? Did you have hot weather in...
