more lightfastness notes

Made in 2013, “The Difference Between A Plum” has travelled a lot of places, without due care as to light conditions. It’s been in well lit galleries, dim areas, fluorescent light, daylight and gawdz knows where else as it made the rounds to various shows. While it’s hard to “match” photos for colour truth, i think these are both very true to the colour it was when made, and the colour it is now.

Iron was integral here as a mordant. Iron deepens and “saddens” colours, can shift to deep purples, blues, garnet, greens, greys and browns, depending on the dye used. (In this case, brazilwood.) It can weaken fibres as well, if the concentration (know as WOF, or weight of fibre ratio to mordant/dye) is too high. I’m pleased to say the fabric still seems quite strong, despite the heavier rust concentrations, though of course, i’m not swinging from the chandelier to test the fact 🙂

Brazilwood is NOT a good dye for lightfastness, though it holds up well to wash fast tests. (Great, you can only wear it in the dark, and wash it in dim light….) BUT surprisingly, this piece is not that different from when i made it six years ago.

brazilwood lightfastness after 6 years

detail of “The Difference Between a Plum” 2013, 6 years later

It is noticeable, and yes, 6 years is not that long, BUT i’m still quite happy about the effect time has had on it.

I definitely wouldn’t advise this for clothing that would be worn a lot, or an art piece in a very bright room, but as an artpiece, the evolving colour change is interesting. I wonder how much lighter it will be in another 6 years, or is there a point where residual colour stays?



a natural moon

I’ve been slowly (and not so diligently, as other pursuits in the studio have “interfered”) working on this indigo moon, using my newly dyed naturally dyed threads. This is a lesson in itself, as the indigo i’m working on is strong enough to overshadow certain colours, necessitating some more neutral backgrounds for future plans/use.


The moon is worked with cotton, silk, silk/wool blend and wool threads in cochineal, osage, logwood, and privet berries, with the brown of the seeds coming from potassium permanganate (actually an inorganic compound). I found a walnut bath i had stored several years ago, when i was setting up in the basement, and shall test to see if it’s still “live”, for some of my browns in future, though i do love all the permutations the PP gave on the skein of cotton. On the background surround, in cotton, silk, wool and silk/wool, the colours i used are privet berry, cochineal, brazilwood, rhubarb root, hollyhock (and that’s where the “oh-oh” happened, as some of the colours are so soft, they are barely discernible), osage, logwood, and sandalwood. Using pre-mordanting (VERY important), and post modifying methods, changes the colours to a wide range. (Ha, just realized i used none of the wonderful madder results!)

I have two other moons still in the finishing stages, and hope to get them done soon too! All will be in the shop.
