Shades of yellow

I was going to create separate posts for each of the dye materials I used for my solar dyeing experiment, but they all turned out to be yellow, more or less. Not much difference there, so why make separate posts?

For posterity's sake, here is what I did:

Zinnia blossoms (dried):
  • Oops - didn't crush dried blossoms before using
  • Oops - didn't weigh blossoms before using
  • Half in one mason jar with tap water (neutral pH), half in another jar with well water (oops - didn't check pH of well water, assume it is neutral)
  • Set jars in sun for three days
  • Drained blossoms and discarded
  • Using cold alum mordanted Cascade 220 - one mini skein (50 yds) in one jar, one in the other jar
  • Set in sun for two days

Lobster mushrooms:
  • Oops - didn't chop mushrooms before using
  • Oops - didn't weigh mushrooms before using
  • Half in one mason jar with tap water (neutral pH), half in another jar with well water (oops - didn't check pH of well water, assume it is neutral)
  • Set jars in sun for three days - got kind of foamy
  • Drained mushrooms and saved them for future use
  • Using rhubarb leaf mordanted Cascade 220 - one mini skein (50 yds) in one jar, one in the other jar
  • Set in sun for two days
  • Mold in well water jar stained the yarn a bit

Oak galls:
  • Oops - didn't crush galls before using
  • Oops - didn't weigh galls before using
  • All galls in a mason jar with tap water (neutral pH)
  • Set jar in sun for a three days
  • Drained galls and saed them for future use
  • Using unmordanted Cascade 220 - one mini skein (50 yds) in jar
  • Set in sun for two days

I am letting the used mushrooms dry out, to be chopped or crushed, to see if I get more dye from them using heat. Similarly, I'm letting the used galls dry, to be crushed, to see if I get more dye from them using heat; they can still be used to mordant fibers even when no dye left.

I thought solar dyeing would be easier than heating up pots of dye baths, etc., and it is, but the results were not all that impressive. Of course, I just jumped in without doing any research. I may try solar dyeing again, but with more care.
