Mysterious chemistry 🙂 These are the oak leaf results.
Quite chocolate coloured on its own!!! I’m sure the first extraction, the first thread in the photo below, proves that more WOF is needed, as i’d love to get that ON fabric or threads! Even though the pot was positively solid with the leaves, i’ll do extraction by soaking/simmering for two days, then remove and add new/more leaves and repeat the process.
Oddly the UNmordanted silk took the colour better, whereas the uptake on previously mordanted cotton was expected.
I have also discovered that my thread skeins from this batch were looped too tightly to either be scoured properly, or mordanted thoroughly, hence the “variegation”–even though i loop quite loosely, it still had an effect. (lesson learned there: DON’T loop)
The colours are softly pretty but not terribly exciting, however they are good base colours for overdyeing, and are obviously *all* mordanted now, as that’s what oak does 🙂 I still have to do post mods to see what colour changes i can get (nothing earth shattering expected), but it *is* good to see what colours one can forage locally.
I’ll still collect more of the oak leaves as they are plentiful and falling anyways. And no one else uses them, just bags them up and sends them to the city compost facility! Also on the list is Cottonwood (a poplar species), very prevalent in my neighbourhood.
