Fastness of Callery Pear and Honeysuckle
Lightfast test results for Callery (Bradford) Pear Bark, Leaves, and invasive Honeysuckle leaves, and leaves with iron.
This is followup from a post I made a few weeks ago, dyeing with invasive plants. These are all on wool yarn, scoured with Dawn and mordanted with potassium aluminum sulfate. All dye baths were set to ph of 7.5-8, with at least 200% wof in dyestuffs. The bark was the trickiest, needing a precise temperature to bond with the yarn.
Sadly, the chartreuse is not lightfast, but the yellow it faded to is still quite nice and bright. Considering I’ve seen other natural dyes fade to nothing, I’d say the rest are decently lightfast.
