Šentjanževka je carica - (2) - St. John's wort rules

Kot sem omenila v zadnji objavi, še ni bilo konec mojega ekperimentiranja s šentjanževko. Še naprej sem uporabljala isto barvilno kopel, delno do zelo izrabljeno. Barvala sem bombažno, volneno in laneno prejo. Enobarvno prejo sem dobila z barvanjem cele štrenice v kopeli, melirane pa sem dobila tako, da sem vlažno štrenico obesila nad lonec in v takočino potopila samo tretjino. Različna barvila, ki jih vsebujejo cvetki šentjanževke, so potovala novzgor po preji 24 do 48 ur in se ustavila različno visoko. Najbolj je bilo to opazno na volneni preji, kjer so nekatera mesta vijolična in zelenkasta (samo kaj ko se na sliki to ne vidi). Idejo sem dobila pri ascendentni kromatografiji - uf, kako znanstveno to zveni, mar ne! Žal pa vsi ti poskusi niso ponovljivi - preprosto povedano, iste barve lahko ponovno dobim zgolj slučajno - adijo znanstvenost :-( As I said in my last post that was not yet an end to my experimentation. Using the same, partly to very exhausted dyeing bath from St. John's wort flowers I dyed some cotton, wool and flax yarns. The solid colours were obtained by immersion dyeing while the variegated colours were obtained by suspending moist yarn over the pot, with the lower third of the skein immersed. I let the different colours climb up the moist yarn over 24 to 48 hours: they fixed at differing spots, which may be seen on the wool yarn with purplish and greenish spots (but the photo fails to show it). I was inspired by ascending chromatography - wow, this does sound scientific, doesn't it! Alas these experiments are failing in repeatability - saying in plain words, I can't obtain the same colours except by chance - very unscientific:-( Nadaljevala sem z isto delno izrabljeno barvilno kopeljo iz cvetov šentjanževke. Od leve desne si sledijo: bež bombažna prejica za vezenje, bela bombažna prejica za vezenje, bel lanen sukanec za klekljanje, bela bombažna prejica za vezenje, bela bombažna prejica za vezenje, +železova kopel, Vse so bile čimžane z galunom+pralno sodo (skupaj). bež bombažna prejica za vezenje, čimžana s taninom, bež bombažna prejica za vezenje, čimžana z galunom+pralno sodo, +železova kopel. Eksperimentiranje mi je bilo v užitek prav toliko kot sem vesela rezultatov. Vedno mi je hudo, da ne morem pokazati pravih barv: imam dobro kamero, a kaj ko so barve varljive, naravne pa še toliko bolj. Kar ne morem nehati ekperimentirati s šentjanževko. Verjetno bom septembra eksperimentirala z zrelimi rastlinami, z bunkicami s semeni in s posušenimi rožami. I went on with the same partly exhausted dyeing bath from St. John's wort flowers. From left to right they are: beige cotton yarn for stitching, white cotton yarn for stitching, white flax yarn for bobbin lace, white cotton yarn for stitching, white cotton yarn for stitching with iron afterbath, All were mordanted in alum and washing soda (together). beige cotton yarn for stitching mordanted with tanin, beige cotton yarn for stitching, mordanted in alum and washing soda, with an iron afterbath. I enjoyed the experimentation as much as I love the results. It always hurts me I can't show the real colours - the camera is a good one but the colours are tricky, and the natural colours even more so. I can hardly make myself stop experimenting with St. John's wort. I believe in September I'm going to experiment with mature plants, with seed balls and with dried material.

I didn't get anything as near this pretty when I tried dyeing with St Johns Wort. Did you need high temperatures? I used a slow cooker in the garden.

lovely shades of St.Johns Wort!

I've been using St John's wort but have not gotten such a variety. I used alum and unmordanted silks. Lovely .... really lovely.

Jasmine, Dorie and Joei, thank you for your comments.
Jasmine, I used various temps - from slow dyeing during two days at temps around 30 to 5o degs Centigrade for some batches at quite high temps for cotton yarns, near boiling, or at least fuming. I think higher temps favoured the golden and greenish colours from fresh dyeing bath (of flowers only).
Wish you all such delight as St. John´s wort gave me this summer.
